Montana Natural History Center

Montana Natural History Center Ice Age Floods National Geologic Trail  The mission of the Montana Natural History Center is to promote and cultivate the appreciation, understanding, and stewardship of nature through education. Founded in 1991, MNHC was the brainchild of a group of educators who were involved in various efforts to educate both kids and adults about the natural history of western Montana, and who decided to unite those efforts into one environmental education organization. MNHC provides nature education programming for people of all ages through summer camps, kids’ activities, Visiting Naturalist in the Schools, Master Naturalist certification courses and Field Days, evening programs, Field Notes on Montana Public Radio, museum tours, and more.  We have a variety of exhibits that focus on the flora, fauna, geology, and ecology of our beautiful state. Please stop by and visit! MNHC often partners with the Ice Age Floods Institute to share fields trips and lectures about the Ice Age Floods.   MNHC has exhibits that help visitors explore the Glacial Lake Missoula and Ice Age Floods. Learn more at:Explore Glacial Lake Missoula | Montana Natural History Center (montananaturalist.org) The Glacial Lake Missoula Chapeter of the Ice Age Floods Institue also produced a short movie about Glacial Lake Missoula. You can find a link here. Quick Facts Location:120 Hickory Street, Suite A, Missoula, Montana

Bison Range

February 5, 2023

Bison Range The Bison Range was established by President Theodore Roosevelt in 1908 to conserve the American Bison.  Since that time it has been managed as a wildlife refuge and native grassland. Today the management is done by the Confederated Salish and Kootenai Tribes. The range is a small, low-rolling mountain connected to the Mission Mountain Range by a gradually descending spur. Range elevation varies from 2,585 feet (788 m) at headquarters to 4,885 feet (1,489 m) at High Point on Red Sleep Mountain, the highest point on the Range.  Much of the Bison Range was once under prehistoric Glacial Lake Missoula. The upper part of the Range was above water. Red Sleep Mountain scenic drive leads to this high point, which has spectacular views across what was once the lake to the Mission Mountains on the other side.  Other flood features are evident on Buffalo Prairie scenic drive. Old beach lines (strandlines) can be seen on north-facing slopes and some large erratics are located near the old corrals. There is a visitor center near the entrance which has a display and videos of Glacial Lake Missoula as well as information on the tribes of the Flathead Reservation and the abundant wildlife, including birds, bears and antelope.  There is also a gift shop.  Camas Prairie ripples and several other important features of Glacial Lake Missoula are in close proximity to this site, much of them are located on tribal lands.  The entrance is off US 93 and MT 212 N about an hour north of Missoula.

Farragut State Park

August 12, 2022

Farragut State Park Ice Age Floods National Geologic Trail Farragut State Park is located at the “breakout” of Glacial Lake Missoula floods, where the ice dam in the Clark Fork valley and the 20-mile-long tongue of ice occupying the Lake Pend Oreille basin failed. From there, a torrent of water and ice burst from the south end of the lake. Farragut State Park is located at the “breakout” of Glacial Lake Missoula floods. Failure of the ice dam in the Clark Fork valley fractured and broke apart the 20-mile-long tongue of ice occupying the Lake Pend Oreille basin, and a torrent of water and ice burst from the south end of the lake. That churning slurry of flood waters, ice, boulders and other debris erupted from the south end of Lake Pend Oreille, flowing 2000 ft deep across Farragut State Park. Nearly all of the water escaping from Glacial Lake Missoula passed through this area. Discharge estimates range from 14 to 21 million cubic meters per second! Vic Baker’s definition of a megaflood is one which has a discharge of at least 1mil cubic m/s, so we are possibly looking at ground zero for the worst Pleistocene flood in the world. Farragut State Park includes many geologic features left by glaciation and megafoods.Hoodoo channel, an abandoned outlet of Lake Pend Oreille provided a pathway for late-glacial meltwater and for the last outbursts from Glacial Lake Missoula. The channel is marked with a number of closed depressions, probably the result of melting icebergs. One of the largest of these features have been proposed, including kettles, potholes, and sub-glacial meltwater. Some of that debris was deposited to form the Rathdrum Prairie Outburst Plain, an extensive, heterogeneous mix of flood deposits. Farragut State Park offers unique scenery, history and an abundance of recreational opportunities. Quick Facts Location:13550 E. Hwy 54 Athol, ID 83801

Celebration Park – Home of Melon Gravel

July 10, 2026

17,000 years ago, a massive Ice Age lake – now called Lake Bonneville – filled a large portion of present-day Utah. As temperatures changed, the influx of ice melt caused the lake level to rise. In addition, the Bear River, once a tributary of the Snake, was diverted by volcanic activity back into Lake Bonneville. These factors ultimately led to the breaching of a sedimentary rock dam at Red Rocks Pass, Idaho. There was only one ice-age Bonneville Flood because Lake Bonneville broke through a rock dam, unlike the Missoula Floods whose glacial ice dam repeatedly dammed Glacial Lake Missoula, then broke and rebuilt.  1,100 cubic miles of Lake Bonneville water rushed through the Snake River Canyon, and it took only six weeks for Lake Bonneville to empty the equivalent volume of modern-day Lake Michigan. The Great Salt Lake we know today is a remnant of Lake Bonneville, but at one tenth the size, it is a mere puddle compared to what the lake used to be.  The power of this catastrophic flood widened canyons as the force of the water pulled huge chunks of basalt off the cliffs and tumbled them around, smoothing their jagged edges along the way. As the canyon width narrowed, the force and velocity of the flood increased. Wherever the canyons widened, the flood lost force and velocity, the waters slowed and began dropping its bedload – in this case, giant tumbled basalt boulders instead of your typical river gravel.  These flood-rounded boulders, named melon gravel due to their distinct shape, are scattered over vast areas of land. The rocks’ unique outlines and smooth surfaces caught the eye of Native American tribes in the area, who have used them as canvases for petroglyphs for thousands of years. Visitors can see the medium sized flood deposits just outside the visitor center, or hike upriver to see gigantic melon gravel the size of heavy-duty trucks.  Celebration Park is located in the Snake River Canyon, approximately 23 miles south of Nampa, Idaho. It is home to an enormous melon gravel field deposited by the Bonneville Flood.
