Lake Lewis High Water Marker

Lake Lewis Wayside

Friends of Badger Mountain

Image you are standing at the ancient shore line of Lake Lewis and the Columbia Basin to the north is filled with water. At this stop you will find a high water marker and a wayside exhibit about the Lake Lewis islands who were created when the Missoula Floods formed hydraulic ponds here. At the wayside, learn about the geological evidence supporting the amazing number of floods.
