Landslide DepositsQls

Landslides identified on this quadrangle were mapped from stereopairs, black and white 1:20,000 scale aerial photographs flownbetween 6-6-58 and 9-7-58. As a result these maps can be usedto identify areas that are vulnerable to slope failure, but are not anup to date assessment of all landslides for the area.
