Along the ICE AGE FLOODS
NATIONAL GEOLOGIC TRAIL

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.

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 

The Paradise Center Ice Age Floods National Geologic Trail Paradise Center, formerly the Paradise Elementary School, is a community, visitors, and arts center in the old railroad community of the same name.  Just below the confluence of the muddy Clark Fork and beautiful blue Flathead Rivers, 70 miles northwest of Missoula, the area was repeatedly inundated by Glacial Lake Missoula, leaving many visible features in the area such as gulch fills, kolks, and lake bottom sediment bluffs. It is on the route between the Camas Prairie Ripples and Eddy Narrows.   Inside the school is a unique interactive 3-D topographical or relief map of the entire area covered by Glacial Lake Missoula and an extensive display of information about the Lake as well as other topics of interest to the area.  Outside on the grounds is a playground and an outdoor walking loop with a dozen or so displays of interest such as the former railroad roundhouse.  A model railroad set-up is also found inside the center. This area can easily be reached directly from the St. Regis exit from I-90 by following the Clark Fork River where flood waters turned sharply to the north, carving out the narrow valley along scenic route 135 to the junction with MT-200. Scour marks and displaced boulders are visible from the road, and it is especially lovely when the larch trees turn bright yellow in the fall. This route also takes you past the historic Quinn’s Hot Springs Resort.  ANNOUNCEMENT: The Paradise Center hours are seasonal, generally Wednesday thru Saturday, 11am-3pm in the summer.
