Open-File Report 79–1314
Landslides and Related Features, Pennsylvania [Pittsburgh
1- by 2-Degree Sheet]
by J. S. Pomeroy and W. E. Davies
The maps on landslides and related features in the Pittsburgh 1- by 2-degree quadrangle were prepared by the U.S. Geological Survey in the late 1970s as part of an Appalachians-wide study of landslides. The report is a compilation of 128 quadrangle maps at 1:24,000 scale.
Limitations and Appropriate Use of the Maps
The features shown on the maps were identified from aerial photographs. Field checking was minimal (average one day per quadrangle of field work). The maps are not intended to be used to indicate landslide susceptibility of specific sites, but rather as a guide to areas where more detailed investigation is appropriate when making decisions about land use or development.
The following files contain important information concerning the content, completeness, and accuracy of the features shown on the maps and the quality of the images. It is the responsibility of the user to read these files before using the maps, and each user is responsible for the appropriate application of the data.
