Montana - Places to GO and Things to DO

Montana Natural History Center

August 13, 2022

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.

Eddy Narrows

August 12, 2022

Eddy Narrows Ice Age Floods National Geologic Trail Eddy Narrows is a 10-mile long canyon between Plains and Thompson Fall along the Clark Fork River. Here all of the waters from the northern and eastern arms of Glacial Lake Missoula converged and picked up speed as they were forced through this restricted area. The steep valley walls are bare of talus and soils up to the level estimated to be the highest level of the lake (1000 ft), and there are polished grooves in the bedrock on a bench 340-400 feet above the Clark Fork River that run parallel to it. Since there is no evidence of glaciation in this area, the only explanation is the rapid draining of Glacial Lake Missoula. Using the dimensions of this flume-shaped area of the canyon, which controlled the rate of flow of water surging through it, in 1942 J.T. Pardee was able to calculate maximum speeds approaching 80 mph, emptying Glacial Lake Missoula in as little as three days. There are pullouts along MT-200 at either end of the narrowest part of this section marked for observing big horn sheep with Glacial Lake Missoula signage at the one between mileposts 59 and 60 at: 47.537940, -115.071654 Quick Facts Location:Between Plains and Thompson Falls, MT

Museum of North Idaho

August 13, 2022

Museum of North Idaho IceAgeFloods National GeologicTrail “The Museum of North Idaho collects, preserves and interprets the history of the Coeur d’Alene Region. to foster appreciation of the area’s heritage.” In the 1960s, the North Idaho Hoo Hoo Club, an organization of loggers, lumbermen and foresters, first entertained the idea of establishing a museum. They incorporated on May 1, 1968 for a museum focusing on the history of the Coeur d’Alene Region (Kootenai, Benewah and part of Shoshone counties). Through the efforts of volunteers and community support, the Museum opened its doors on the North Idaho College campus on July 28, 1973. In 1979, they remodeled a City-owned building and relocated to its current location. Quick Facts Location: 115 Northwest Blvd, Coeur d’Alene, ID 83814Phone: (208) 664-3448 The Museum is open Tuesday to Saturday from 11 am – 5 pm.

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.

Lake Pend Oreille

August 12, 2022

Lake Pend Oreille Ice Age Floods National Geologic Trail The Purcell Lobe of the Cordilleran Ice Sheet repeatedly formed a 2000′ tall ice dam in this area, which backed up Glacial Lake Missoula and eventually burst catastrophically, releasing Ice Age Floods as often as about every ~10-60 years. Lake Pend Oreille is the largest lake in Idaho. The lake level is 2062 ft above sea level, with the surrounding terrain as high as 6002 ft. With a maximum depth of 1150 ft, this lake is the 5th deepest in the US. The location of the lake is probably related to an old river valley controlled by faults. The Lake Pend Oreille basin was carved by the repeated advances of Pleistocene ice and scoured by Ice Age Floods. With the waning of flood waters, the basin was filled with glacial out-wash and flood deposits. The lake is dammed at the south end by thick glacial and flood deposits that mark the beginning of the “Outburst Deposits”Quick Facts MANAGED BY:US Forest Service
