What evidence shown on the map and stereogram suggests that the material in the deposit does not consist of coherent bedrock? (Hint: Contrast the appearance of the deposit with that of the surrounding mountain front.)
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).
Very irregular contour lines on gentle slope suggest loose, incoherent material; small ponds and depressions are still present on deposit.
