Rockglen is situated in the Wood Mountain Uplands. Because this area was not affected by the last glacial movement, our fossils are often not buried by tons of overburden. Over the years these hills have yielded trilobites from 425 million years ago and brontosaurus skeletons from 100 million years ago. A giant sea turtle from 63 millon years past has been excavated in the Killdeer area, and many fossils of prehistoric mammals including the three-toed horse, squirrels, mice, rabbits, weasels and shrews from 15 millon years ago have been unearthed just a couple of miles west of town. 

Petrified wood are readily found, the largest being a four by thirty foot tree which was unearthed a few miles east of Fife Lake Village. Imprints of tropical plants and other plant fossils may be found between layers of sandstone and in the lignite coal seams in our area. 

It was only after the last period of glaciation some 18,000 year ago that mankind showed up in Saskatchewan as evidenced by a stone spearhead, estimated at 10,000 years old, found near Mortlach a few miles north of here. The Aboriginal people have left a rich heritage of stone-age culture in our area, with scrapers, stone hammers, grinding tools, teepee rings and arrow heads to be readily found throughout the district. Some of these relics may be seen at the Tourism Information Station.

Our more recent history, the stories of the first white settlers, farmers, ranchers and business men, can be read in Volumes 1 and 2 of our history books "The Rolling Hills of Home" which are available at the Tourism Information Station. Stop in to browse and have a coffee.


Geology Class 001 – a Cram Course in Basic Geology

Geology is the study of rocks and soil. Aside from farmers, the first people who really needed to understand the geological relationships between different rock types were miners. They eventually realized that rocks developed or were laid down in layers (or strata) and that the oldest rocks were there first and are in the deepest layer. Besides this, they learned that natural geological processes were fairly uniform in frequency and size throughout time, allowing them to recognize rock pattern successions, or geologic periods. 

Over the years, divisions of geologic time have been described. The largest time units are called Eons, consisting of the Precambrian Eon and Phanerozoic Eon. The geology of Saskatchewan conveniently displays rock from both, with the entire northern third of the province being part of the Canadian Precambrian Shield. We assume that during the Precambrian Eon algae, fungi and single-celled creatures developed, as few fossils exist. 

In the southern two thirds of the Province the Precambrian rock is covered with flat lying sedimentary rocks that have been deposited in what is known as the Phanerozoic Basin.

The Phanerozoic Eon represents the time during which the majority of visible organisms – at least those with shells and skeletons -- lived. It covers the last 543 million years of time and has been divided into three Eras; the Paleozoic Era, the Mesozoic Era and the Cenozoic Era, from oldest to youngest. (“Paleo” meaning ancient, “Meso” meaning middle and “Cen” meaning recent) while the “zoic” part comes from the root word “zoo”, which means animal. The Paleozoic Era has been called the “age of fishes”, the Mesozoic Era – “the age of Dinosaurs” and the Cenozoic “the age of mammals” although there is considerable overlapping of species between them, i.e. some ancient forms live even today.

The Cenozoic (most recent) Era is divided into the Tertiary Period and the Quaternary Period. The Cenozoic Era consists mostly of the Tertiary Period, from 65 million to 1.8 million years ago. The Quaternary Period is from 1.8 million years ago until today and is divided into two Epochs: the Pleistocene Epoch, or age of glaciation, and the Holocene Epoch, which is the last 10,000 year post-glacial epoch in which we live. 

Having escaped glaciation, the geology of the Rockglen Region encompasses a treasure trove of artifacts from the late Tertiary Period through the entire Quaternary Period, containing potential mining sites for coal, bentonite, kaolinitic and ceramic clays. In the past, placer gold had been found here near Fife Lake and Kimberlite and Garnet indicate possible Diamond potential, which is currently being actively explored near Lisieux. Ravenscrag gravel pits and badland escarpments lay it all open to you in the Rockglen Region … it’s a Geologist’s dream!


Echoes from Ages Past

Geological history is measured in very long periods of time. Here we will just briefly touch on findings of geologists as related to the periods that left us certain famous prehistoric fossils and petrified fauna which have been found in our area.

Going back 600 million years ago, our area remained rock which was formed when the surface of the molten stuff of the earth cooled. There was no soil. When someone is drilling for a well or an oil well and he remarks, “I hit ‘bed-rock’ “— That is it!”  Wind blew incessantly and rains fell. Sediments from the rock washed into the shallow Cambrian Sea to the west of us. Life began in the seas. Millions of tiny invertebrates, such as trilobites, lived in the seas. Their fossils are found in Cambrian rock. Trilobites persisted on earth for 325 million years.

Later, the Ordovic Sea flooded seventy per cent of North America, including our area. More sediment washed from the rock. This sea dried up for millions of years.

Again, 425 million years ago, our area was sub merged by another sea, the Silurian Sea; wherein millions of trilobites and other sea animals lived.

Effie Mattson found a fossil of one of these trilobites in a rock on top of a hill north of Rockglen.   It is hard to believe that, 400 million years ago, our hills were a sea floor where marine arthropods, such as trilobites, lived and crawled in millions.

About 405 million years ago, during the Devonian Period, for 65 million years, seas periodically covered the Great Central Plains, including our area. These seas were warm and shallow and teemed with billions of in vertebrates and water plants — forerunners of enormous ferns, etc. which developed as seas were drying up.

Mr. Belbeck discovered an imprint of a huge leaf resembling a palm leaf, in lignite coal which he dug from the bottom of Fife Lake when it dried up in 1937.

 Huge sea creatures evolved and developed lungs so they could crawl from one body of water to another during the next 65 million years — the Carboniferous Period.

By 100,000,000 years ago reptiles had developed as far as the mighty brontosaurus, the largest land animal that ever lived — A vegetation eater.

The Age of Reptiles also produced the flesh eaters, such as the TRYANNOSAURUS. The almost brainless DINOSAURUS were no match for these fierce reptiles.

Later, a slow change came over the climate of the earth — the tropical forests receded — temperate and then cold regions began to spread — and the giant reptiles, whose blood followed the temperature of the air, died by the millions and vanished.

During the next 50 million years — the Permian period, millions of huge sea creatures evolved into hundreds of varieties of huge land creatures (reptiles) which dominated the warm, humid earth of our area during the Triassic period up to 181 million years ago.

In 1919 a Brontosaurs, 66 feet long, was excavated from the area west of Killdeer, and shipped to Ottawa.

 The Jurassic Period, which ended 100 million years ago, produced two different kinds of huge reptiles. As well as the almost brainless vegetation eaters, such as the Brontosaurus which was the largest animal that ever lived, there was the fierce, flesh eating Tyrannosaurus.

In 1965 the fossil of a Tyrannosaurus, estimated to be 15 feet long, was excavated from an area west of Killdeer and sent to Ottawa. The event that led up to this excavation was the discovery, by Martin Nagel and Nick Moneo, of the fossilized vertebra of a dinosaur. This vertebra was sent to Regina Museum where geologists saw it and became interested. Martin Nagel and Nick Moneo were at the scene of the excavation and said the fossil was only about two feet below the surface of the earth.

During the next 72 million years — the Cretaceous Period, the last great sea covered part of The Great Central Plains. This sea teemed with fish and huge sea animals.

A giant sea turtle, 12 feet long, was excavated from the area west of Killdeer. It was believed to have lived 100 million years ago.

Many here have discovered rock containing numerous shellfish fossils. These animals are not only one of the largest groups of animals today; they are also one of the oldest. Fossil remains indicate that they have been common in the seas for more than 500 million years.

About 63 million years ago, the Tertiary Period, there were no mountains between us and the Pacific Ocean. Then the top crust of rock on the earth’s surface was broken and heaved to form jagged ridges of mountains. This brought a tremendous change to the plains region east of this ridge. Shut off from the warm, moist winds of the ocean, the climate changed from tropical to temperate, with cold north winds. This may have finished the giant reptiles whose blood followed the temperature of the surrounding air; for they died by the millions and only their fossils remain to prove their existence and domination in this region for 100 million years.

No more great seas flooded the plains. Winds blew incessantly and caused tremendous dust storms; so our area was a desert. Then rains fell and filled rivers which carried rock particles to form sand and clay. After millions of years of weathering, by wind and water, eventually soil was formed on which plants flourished; also, thousands of mammals from mice to wooly mammoths.

By 25 million years ago the mountains to the west of us were worn down and once again moist winds made our climate sub-tropical. Great trees flourished, died, and were buried to form lignite coal and petrified wood.

A few miles east of Fife Lake village, a petrified tree was found which was about four feet in diameter at the base and long enough to reach 30 feet through a hill.

The lignite coal here is believed to have been formed in that period. It is close enough to the surface to be strip- mined.

In 1955 a biologist from Ottawa discovered fabulously rich fossils in Lawrence Yost’s gravel pit and along the No. 2 highway’ cut banks close by. They found 15 million year old bone fossils of mammals, including the three- toed horse, squirrels, mice, beavers, rabbits, weasels and shrews; also horn-cores of small antelope.

Again, in 1967, two biologists from Toronto came to Lawrence Yost’s farm but found nothing much. Lawrence suggested that they should look at the sand pit of John Kleinfelder. Here they found the richest deposit of small mammal fossils so far found in North America. As well as bones of small mammals which they found, a nearly complete skull with most of the teeth, of a three- toed horse, was found by Leonard Kleinfelder.

A tusk and other bone fossils believed to have been those of a four-tusked mastodon were found by John Kleinfelder. These were identified by Dr. L. S. Russell, chief biologist for the RoyalOntario Museum. The four tusked mastodon is an extinct genus of elephants, believed to have weighed up to ten tons, with a length of twenty-two feet and a height of eleven feet.

About 20 million years ago, the climate in our area changed drastically. Warm, moist winds were replaced by cold, dry ones. Tropical plants were replaced by grasses.

Many imprints of tropical plants are found between layers of rock in the hills in our area.

 In the era 15 million years ago, these plains were populated by hundreds of species of mammals — grazing and carnivorous.

One million years ago great glaciers covered almost all of Canada. There were four glacial periods, with periods of temperate climate in between. In glacial times the average thickness of the ice was 8000 feet. As the ice masses advanced in a southerly direction, it is estimated that they covered almost the whole of Saskatchewan at one time.

 The area around Rockglen is one of four, in North America, unaffected by glaciations. No glacier buried our fossil treasure under tons of earth and debris. The other three unglaciated areas are at Cypress Hills, Sask., Porcupine Hills in Alberta and an area in the State of Wisconsin, U.S.A.

 This was brought to our attention on Oct. 13, 1973, when Rockglen and district was included in a tour by Dr. Caviades and 34 of his Geomorphology students from Regina Campus of University of Sask. When they made a study of the unglaciated surface around Rockglen, they found rock formations with vegetation imprints, petrified wood specimens and various examples of erosion which provided evidence of an earth surface 60 million years old.

 So, as your mind goes back to the pioneers, the Indians and the buffalo; let your imagination wander back further — back to a time when most of our land was covered with huge beds of ice; still further back to when it was covered with lush, tropical growth and millions of huge creatures; again, back to when it lay at the bottom of huge seas; then, once more, back to when it lay at the bottom of huge seas; then, once more, back to when it was solid, hard rock, formed when the molten surface of the earth cooled. What an interesting journey your imagination will have. Effie Mattson


The Rockglen area is one of the richest Miocene Era fossil sites in Western Canada, with many fossils having been found on the Kleinfelder and Koch farms a couple of miles west of the Town of Rockglen.  Should you be visiting the Royal Ontario Museum in Toronto or the Royal Saskatchewan Museum in Regina, most of our local fossils will be listed as “Kleinfelderii” specimens.

Mastodonts were present in the area from sixteen million years ago until their extinction between ten and eleven thousand years ago, likely by the Clovis Paleo-Indians or possibly by loss of habitant during the last ice age.

They were distantly related to Mammoths and modern elephants and ranged over the entire North American Continent from the Honduras to Alaska with various species measuring up to thirteen feet in height at the shoulder.  Their long, curved upper tusks were shorter than the woolly mammoth and less curved, while the lower two tusks of our locally found mastodont, which can be seen in the Royal Museum in Regina, are much closer together and slope upward, being helpful in ripping up the small trees and tree branches that formed much of their diet. 

“Oliver”     Rockglen & District Tourism is pleased to display the metal sculpture Oliver, designed and created by Melvin Monea. Oliver represents the fossilized remains of a four tusked mastodont found just west of Rockglen and commemorates our history before and during the last ice age when, from 16 million to 10 thousand years ago, mastodonts roamed our hills and valleys. This metal sculpture of “Oliver” is also a tribute to life in early years of the Rockglen region when the Town boasted of having several implement dealers.  Mr. Monea has created this impressive metal sculpture from many of their Oliver and other machinery parts as a lasting legacy to our farming community and to our rich archeological history. You can see several of “Oliver’s” genuine fossils here at the Effie Mattson Nature Walk and Archeological Centre and at the Royal Museum of Natural History in Regina.

From existing evidence, it seems likely that our area was first inhabited by man shortly after the disappearance of the last ice sheet which covered our land, starting about 18,000 years ago.

These first men are thought to have come from Asia, across the land bridge, to our continent; then traveled down the coast, through the mountain passes and reached our plains. They were meat-eaters and, for food and clothing, killed the massive, shaggy bison which were ancestors of our ‘buffalo’.

A stone spear head was found at Mortlach by John Scott, Effie Mattson’s father. It was claimed, by scientists, to have been used by man 10,000 years ago.

Thousands of years later, when men from another continent came here, they found this early man had developed a way of life very well adapted to his needs. These men were misnamed ‘Indians’. In our area these native people were still mainly meat-eaters and used tools made from stone to kill and prepare their meat and to prepare the skins for clothing and homes.

Some of these stone tools that are found here are the stone axe or hammer, stone points for arrows and spears, stone knives, stone scrapers and stones on which meat and berries were pounded together before being dried.

They also carved some implements from bones, horns and antlers. Some of these were spearheads, hunting knives, scrapers, spoons, awls and needles. Ornaments for their bodies they made from animal claws and teeth, birds’ feathers and shells.

In this area, the large herds of buffalo were their chief source of food, clothing and shelter. To kill one of these huge animals, with bows and arrows or spears, when per formed on foot, was quite a feat.

With the coming of a new race of man, only a few hundred years ago, the descendants of the first man found their way of life threatened and eventually destroyed. Whereas, it took millions of years for early animal life to adapt to changing environment or be extinguished like the huge reptiles; it took only a few hundred years for native man to develop an entirely new way of life.


Gone are the enormous herds of ‘buffalo’ that once roamed over these valleys and plains. Gone are the bands of wild horses that grazed on these hills and in these valleys. Gone! — is surely as the dinosaurs.

When the first of the new race of men came to this area, they found the buffalo still here in large herds of thousands. They also found the native people riding on horses when traveling or hunting.

Often, these horses had been captured from the bands of wild horses which galloped over our hills and valleys. Some of them were believed to have been descendents of horses brought over to the southern part of our continent by the Spaniards. These wild horses were joined by other escaped ones and multiplied until there were many bands.

Some of them were still here when our first pioneers came to the country. They had developed into a hardy breed, well adapted to this climate and terrain.

When Elvin Edwards came to this country, he saw a band of about 70 wild horses that had just been captured. Cowboys were trying to ‘break’ some for riding. Elvin, being young and looking for excitement, mounted and rode two. That band of wild horses may have been the last of the ‘wild ones’ in this area. 


Listen! Hark to the echoes!
Blown by winds for thousands of suns.
The hoof-beats of the free, wild ones.
These hills were ours to roam in,
No one here to deny our right,
Left to us by ‘buffalo’ herds
Who moved on and vanished from sight.
Free as the winds! Not harnessed!
Till man came with his gun and rope
And caught the wild ones and broke them;
Those, not caught, gave up life and hope.
Our bodies they broke to there use;
But our spirits? No! Never! No!
Listen! Hark to the echoes!
Wild and free, o’er the hills they go!

Natural History

Nature at its Best

In this area we’re lucky to have such a large variety of birds. Some of our birds prefer to live near people in our towns or groves. A few we often see are robins, mourning doves, orioles, bluebirds and goldfinches. The lesser known ones may be vireos, warblers and tanagers. We also live near Fife Lake where we find water lovers such as ducks, geese and grebes and numerous shorebirds including the beautiful Avocet and the rare Piping Plover. Besides that, hawks, owls and birds of the open plains such as buntings and longspurs abound.

Many migrating birds fly over on their way north to nest. They arrive in full mating plumage which makes for very exciting bird watching.

This is nature at is its best just waiting to be enjoyed.

Piping Plovers Survive at Fife Lake

Since 1940 environmentalists have been surveying and observing the decline in the number of Piping Plovers all across Canada. By 1985, their numbers had dwindled to fewer than 6000 birds world-wide. It was at that time they were placed on the endangered species list and put under the protection of the Federal Migratory Bird Convention Act and the Species at Risk Act. They are also protected by the Saskatchewan Wildlife Act. Our province has an important relationship with this little shorebird. Saskatchewan has the largest number of Piping Plover sites on the prairies, acting as host to them in more than 64 wetland areas during their northern migration from Texas.One of these wetland basins is Fife Lake, a large water body located 6.9 kilometers east of Rockglen and covering 28 square kilometers. 

This lake is home to a number of Piping Plovers. In 1996, there were 53 adults identified on the lakeshore including 13 nesting pairs, but this population declined to only 14 adults in 2002. The little bird has fallen victim to a number of stress factors. The drought of the last few years, coupled with increased predation, and destruction of the shoreline by cattle, have created difficult nesting conditions and fewer birds have been surviving. A number of initiatives in the area have been started to increase awareness of this endangered species.

Rockin’ Beach Regional Parkhosted two field days this past summer to discuss and demonstrate the plight of the Plover and to outline improvements that are being made. In addition, the Saskatchewan Wetland Authority has begun work with a number of farmers and ranchers in the area to ensure that the condition of the Fife Lake shoreline is maintained or reclaimed. Purging and hummocking of the shore in some areas has created an environment that is unfavorable to nesting by the little bird. Some areas of the shore will be fenced to create guardianship areas and prevent predation, while education and an increase in awareness should help to preserve others.Conservation of the nesting habitat is crucial to the survival of this species. Bird watchers can observe the little birds from canoes with binoculars, or from grassland areas near the shore but far enough away that the birds will not be disturbed.

Though the Piping Plover resembles the larger, familiar Killdeer, there are a number of distinguishing characteristics to look for. The Plover is smaller and lighter in colour, and has only one black neckband compared to the Killdeer’s two. In summer, the Piping Plover is sandy coloured with orange legs, a black headband and a black neckband. Its distinctive bill is orange with a little black tip. The under parts are white and it has a white rump. The birds blend in well with their habitat so observers must take their time and observe quietly in order to spot them.Their distinctive series of melodic “Peep-lo” calls will help identify them. A pleasant afternoon of Plover watching is a great way to enjoy the beautiful landscape of the Rockglen area.


Wild Animals of Rockglen and District

The Wood Mountain Uplands have been home to wild animals since prehistoric times. Escaping the last Glaciation has made possible the finding of archeological fossils of brontosaurus and giant sea turtles, which lived in the Triassic Period 181 million years ago, in this area. Much more recently, about 15 million years ago, numerous primitive mammals lived here, as evidenced by the fossils of Mastodonts, Wooly Mamoths, three-toed horses, antelope, shrews, weasels, squirrels, mice, beavers and rabbits. Most of these have been found in archeological digs as near as two miles form the Town of Rockglen.

For the sharp-eyed visitor, progeny of these prehistoric animals are still to be seen in the area.Bison are present in protected environments, while Mule Deer, White Tail Deer, Elk, Pronghorn Antelope and even a rare Moose roam freely in the valleys and hills. Predators including coyotes, badgers, foxes, weasels, bobcats and a rare lynx may be seen as they prey on jackrabbits, cottontail rabbits, Richardson Ground Squirrels, rats, mice shrews, moles and other small mammals. Raccoons, skunks and squirrels bestow their sometimes unwanted presence in or near our homes, while beavers and muskrats make themselves comfortable in several local creeks. A short time spent watching these natural engineers at work is an education in itself.

In Historic perspective, few places in Canada offer a more comprehensive panorama of wildlife to be seen in its unaffected state, living in a natural balance of death and survival, than can be seen within walking distance or a short drive from here. Refresh your memory of natural history, then bring your binoculars and prepare to be impressed by the inherent richness of your wildlife heritage.
