Murphy 2011 Variable mixture of strata and deposits that have slid to the base of steep slopes of the Little Knife River Valley and tributaries. Landslide Deposits Qls Landslides identified on this quadrangle were mapped from stereo pairs, black and white 1:20,000 scale aerial photographs flown between 6-6-58 and 9-7-58. As a result these maps can be used to identify areas that are vulnerable to slope failure, but are not an up to date assessment of all landslides for the area.
