Includes landforms developed or developing from Late Pleistocene to present. Covers: 1) Texas Mountain, 2) White Coyote Draw, 3) East Evacuation Creek, 4) Big Foundation Creek, 5) Brushy Point, 6) Baxter Pass, 7) Douglas Pass, 8) Calf Canyon, 9) Henderson Ridge, 10) Garvey Canyon, and 11) Middle Dry Fork. 12 plates (1:24,000). 12 plates (1:24,000).

The maps can provide insight into the type and intensity of the formative processes, the distribution or general frequency of incidents in the recent past, and estimates of the type and thickness of surficial deposits that are associated with each unit. Used in conjunction with the other maps, they can aid in locational studies and assist in selection of preliminary designs or mitigation. In later stages they can help in selecting appropriate special geotechnical studies that may be required.
These information, as well as those from OF-86-02 (Folio 1) and OF-86-03 (Folio 2), are included on a 1:500,000 plate in Map Series MS-27, Surficial Geology and Geologic Hazards of the Douglas Pass-Baxter Region, Rio Blanco and Garfield Counties, Colorado, published in 1992.
