Purpose: The purpose of these data is to provide the engineering geologic units and interpretive rock-fall hazard units for the map. Supplemental_Information: Geologic units were defined from field observations and from the use of 1:6000-scale stereographic aerial photographs taken in 1983. Hazard units were interpreted on the basis of the geologic units.

The photographs were registered to a 1:3000-scale paper copy of a USGS Digital Orthophoto Quadrangle (DOQ) from the northeastern quarter of the Mt. Timpanogos 1:24,000-scale quadrangle. A PG-2 photogrammetric plotter (Pillmore, 1989) was used to register the photographs. Once registered, geologic contacts were transferred from the photographs to the 1:3000-scale paper and digitized into the ArcInfo Geographic Information System (GIS). The digitized geologic map was then taken to the field during additional trips in late October and early November, 2004. During these trips, the map was checked for completeness and accuracy, and revisions were made. Our best estimate is that lines are accurate to within several meters.
