Which kind of mass wasting most likely left this deposit, a type of flow or a type of slide? What evidence shown on the map and stereogram supports your answer? (Hint: Note the path taken by the material on its way downslope.)
The following questions are based on Map T-26a, a section of the USGS “Spring Hill, Idaho,” quadrangle (scale 1:24,000; contour interval 20 feet), and Figure 38-9, a stereogram of the same region. The map and stereogram show a large mass wasting deposit at the foot of the Pahsimeroi Mountains in Idaho (44°17'39"N, 113°43'02"W).
