The maps produced were intended to provide information useful in planning and evaluation possible future major relocations of highways, pipelines, and related structures. Mapping was accomplished using aerial photographic interpretation techniques in conjunction with field mapping of keys areas conducted in the summer of 1985. Emphasis was on the surficial geologic deposits and processes and their potential impact on human works. Active landsliding and slope failures are continuing to occur throughout the study area. Aerial photographs were taken in 1978-1979, thus mapping would not show later landslide activities.
This information, as well as that from OF-86-03 (Folio 2) and OF-86-04 (Folio 3), are included on a 1:500,000 plate in MS-27 Surficial Geology and Geologic Hazards of the Douglas Pass-Baxter Region, Rio Blanco and Garfield Counties, Colorado, published in 1992.
