“ Meanwhile, back at the Ranch.” Glaciers pick up and carry rocks, de- positing them as piles of rubble - called moraines - at their foot and along their sides. The results of this are seen extensively in the valley of Nevada Creek and the Blackfoot River, including several areas on Ranch land. The moraines show as rounded grass-covered hills, rising both from the valley floor and as “foothills” to the mountain slopes bordering it. Those which are long and nar- row, found especially along the sides of a valley, are known as lateral moraines, since they were deposited along the side of a glacier. A fine example Glacial Leavings on the Ranch and the Valley 27 prominently seen from ranch headquarters is the one rising immediately behind Helmville, and also one which a stretch of Hwy. 141 follows along its ridge for a couple of miles. Both of these may have been a part of a single lateral moraine which, after the glacier retreated, was cut through by Nevada Creek. Parts of the corresponding later- al moraine on the other side of the former glacier can be seen as some of the foothills on the
