|Pennsylvania (Crawford County), Conneaut Lake — Geology|
|Conneaut Lake is a kettle lake formed by the receding glacier during the last Ice Age, about 12,000 years ago. As the glacier melted, a large block of ice partially embedded in accumulated sediment formed the depression, which became the lake. Prehistoric Mastadon and Woolly Mammoth bones have been found preserved in the layers of silt in and around the lake, giving evidence of their existence during this period. The glacier changed the water flow from the north to south, making it a part of . . . — Map (db m74623) HM|
|Pennsylvania (Crawford County), Titusville — Titusvillia Drakei Caster|
|In ancient seabottom rocks exposed in this stream, the Holotype Specimen of a rare fossil sponge was found by Paleontologist Kenneth E. Caster. In 1939 in recognition of the support which brought the sciences of geology and paleontology to such eminence he named this new species in honor of the oil industry's birthplace and its founder. — Map (db m64970) HM|
|Pennsylvania (Philadelphia County), Philadelphia — Edward Drinker Cope|
|Internationally renowned vertebrate paleontologist and zoologist, Cope lived and worked here in his later years. He wrote many scientific papers describing hundreds of fossils & living animals and is famous for his long-standing feud with O.C. Marsh of Yale. — Map (db m82812) HM|
|Texas (Fisher County), Sylvester — 82 — Adair - Steadman Site|
|In this vicinity is a prehistoric archeological site discovered in 1969 near the Clear Fork of the Brazos River. Archeologists have conducted extensive scientific excavations and attribute most of the cultural materials to the Paleo-Indian Period. The Adair-Steadman site was a large base campsite for makers of fluted points, who were part of the distinctive Folsom Culture between nine and eleven thousand years ago.
Prehistoric peoples chose to live here because of the availability of . . . — Map (db m81124) HM|
|Texas (Kendall County), Boerne — Cascade Cavern|
|Probably formed during the Pleistocene epoch by the
underground passage of the Cibolo River, Cascade Cavern presents an interesting mix of geological, archeological,and historical features. It exhibits a combination of the joint and the dip and strike types of caverns, and is the home of a number of unusual animals, including cliff and leopard frogs, Mexican brown bats, and Cascade Cavern salamanders.
Archeological evidence uncovered near the cave indicates the presence of two Indian . . . — Map (db m46924) HM|
|Texas (Roberts County), Miami — 2039 — Fossil Beds — (three miles southeast)|
|Cited as one of most prolific fossil fields of lower Pliocene age at time of discovery, these beds are about 13,000,000 years old. Geologists of Rio Bravo Oil Company found them in 1928 on C.C. Coffee Ranch, and their reports brought specialists from several major institutions to the area.
The fossil bones buried here included (among others) those of a prehistoric camel, a kind of antelope, horse, bone-crushing dog, mastodon and wild pig.

|Texas (Ward County), Monahans — 3434 — Monahans Sandhills State Park and Museum|
|In these shifting seas of sand, rich in stone evidences of primitive men, today's visitors find flint points, sandstone metates and manos of peoples who were here as early as 10,000 years ago and late as the 1870s. Bones of great mammoths and gigantic bison prove that this desert was in post-glacial times a land of lakes and tall grasses.

while the smaller three toed tracks were made by
one of a number of smaller bipedal carnivorous
spedies. — Map (db m39259) HM|

| In 1849 an 11,000 year old Beluga Whale was found north of this site in what had been the Champlain Sea. Resident J.G. Thorp collected the bones, and naturalist Zadock Thompson assembled the skeleton now displayed in the Perkins Museum of Geology at UVM. — Map (db m75963) HM|
|Virginia (Fairfax County), Great Falls — American Indians of the Potomac River — Riverbend Park — Potomac River Gorge Interpretive Trail|
|Prehistoric people arrived along the shores of the Potomac River some 13,000 years ago. Slowly they transformed from semi-nomadic hunters into farmers and fishermen. Eventually, a group called the Nacotchtanks became the dominant tribe of the Washington D.C. area.
The Potomac River was a heavily traveled trade route by American Indians. In fact the word Nacotchtank translates to mean “at the trading town.” — Map (db m64316) HM|
|Virginia (Westmoreland County), Stratford — The Stratford Cliffs|
|Approximately 17 million years ago, during the Miocene Epoch, these 150-foot-high cliffs along the Potomac River formed the ancient seashore. Rich Miocene fossil deposits, which exist in the 1 1/2 -mile-long series of Horsehead, Stratford and Nomini Cliffs, can only be found in several locations in the world. Fossil remains of salt-water crocodiles, whales, porpoises, turtles, rays and sharks can be discovered along the shoreline. This overlook is one of a few spots along Stratford's northern . . . — Map (db m34585) HM|

|Also known as "Temple of the Sioux," Sundance Mountain rises majestically in the southwest. It belongs to the Bear Lodge Mountain Range, which defines the northwestern edge of the Black Hills. It was named for the Plains Indians' religious ceremony—and in turn it provided the name for the town at its base, which dubbed one of its earliest and most notorious prisoners, the "Sundance Kid." In the Lakota language, the mountain is called Wi Wacipi Paha, which literally means Sun Dance . . . — Map (db m45541) HM|

|Giant cypress trees growing today in swamps (or forested wetlands), such as these found in Louisiana's Pointe Lake, used to grow in Wyoming back when it was a warm, subtropical swamp - about 55 million years ago during the Late Paleocene epoch. Some of these ancient trees were buried under sediment and turned to stone. the three petrified trees located here were found during coal mining operations at the Eagle Butte Mine near Gillette.

|Located a short distance to the east and camouflaged by the red eroded landscape is the Vore Buffalo Jump. This sinkhole served early residents as a slaughterhouse. using the natural pit as a trap, hunters would capture bison in late fall by running a herd over the edge. Once killed, the animals were butchered to provide food and supplies for winter.|

|Wyoming (Lincoln County), Kemmerer — Fossil Butte|
|Fossil Butte is a 50 million year old lakebed and one of the richest fossil resources in the world. It is part of the Green River Formation, a layer of rock composed of laminated limestone, mudstone, and volcanic ash. Complete paleo-ecosystems are preserved in the formation, which is the geologic remnant of the Green River Lake System of the Eocene era. Designated on October 23, 1972, Fossil Butte National Monument encompasses a part of land that was once under Fossil Lake.
