The gently rolling landscape here is typical of the Glaciated Plains, a vast area that extends south from Manitoba and Saskatchewan, through northern and eastern North Dakota, into eastern South Dakota. Glaciers flowed south through this area 12,500 . . . — — Map (db m162958) HM
The badlands you see from here were so named because they were "badlands" to travel over before modern roads were built. Rain, wind and running water have carved these hills. A thick series of shale and sandstone layers, all of these rocks are a . . . — — Map (db m4822) HM
These soft sandstone deposits, built up by wind and water and then carved into strange and fantastic shapes by the same forces, have fascinated man for at least 5,000 years. Note the absence of carvings in the sculptured walls seen in this . . . — — Map (db m154309) HM
The large spherical boulders in front of you are called concretions. They may have any shape, but most are round. Concretions are formed within rocks (shale, clay, sandstone, etc.) by the deposition of mineral around a core. More concretions . . . — — Map (db m88650) HM
The colorful and fantastic shapes along these canyon walls are part of an ever-changing landscape. The horizontal layers of multi-colored sandstone, clay and shale are complimented by scattered beds of lignite coal and patches of pastel . . . — — Map (db m85880) HM
The blue-black popcorn-like soil that caps the plateau 50 feet below this point is bentonitic clay. Bentonite clays flow when wet. This bluish-colored layer can be traced for miles up and down the river. — — Map (db m88636) HM
These small boulders are clues to a fascinating story. Geologists believe they were ripped from bedrock 400 miles north in Canada and carried to this point by a great glacier which covered nearly all North America north and east of here. . . . — — Map (db m88638) HM
These tilted mounds were once part of the higher cliffs beyond. Stream cutting against their base over-steepened the cliffs. During wet periods, blocks of earth slid downhill, retaining their original layered sequence. Can you match . . . — — Map (db m88649) HM
Fort Clark and its opposition post Primeau's Post, as well as that of the nearby Mandan and later Arikara village, were for defense and also served to tap the bountiful natural resources of this stretch of the Missouri River valley. Between 1832 and . . . — — Map (db m162383) HM
Devils Lake The question is often asked where did the name "Devils Lake" come from? Long before European settlers came to this area, local Native Americans fondly referred to the lake as "Mníwakháŋ," meaning water with energy, . . . — — Map (db m242839) HM
Devils Lake is rightly considered to be largely a product of glaciation, but the geologic events that led to its origin began long before the first glaciers came to North Dakota. An intricate series of events, beginning about 65 million years ago, . . . — — Map (db m242838) HM
The stillness of the land is a disguise. Hard infrequent rain attack the loosely cemented clays and sandstones, gouging new gullies and carrying off as much as two to four inches of surface a year from steep, unprotected slopes. At night the . . . — — Map (db m87222) HM

In the natural process of carving away sediments from their banks, rivers and streams meander back and forth across the land. Often times, sharp curves in the river form a loop which is gradually shut off rom the flow of water. The area which is . . . — — Map (db m143015) HM

Overland travelers usually departed from the back gate, which was located just behind where you are now standing. This was the take-off point to the wilderness, trails and gold fields beyond. The vast prairie lay before them.
