Excerpted from the report:

This report presents the results of a comprehensive investigation of the geology and engineering geology of Planning District 9, State of Colorado. Planning District 9 includes the counties of Archuleta, Dolores, La Plata, Montezuma and San Juan.

Within the Planning Districts, specific geologic factors which should be considered to insure safe, efficient and environmentally sound land use decisions. This investigation was done on a reconnaissance basis and the factors include, but are not limited to, the following:

a. Mineral resources which affect land use decisions
b. Massive land movements or other unstable surface conditions
c. Areas of swelling soils, settling soils or other soil factors that will affect foundation construction
d. General areas of flood danger and/or erosional hazards
e. Areas of high water table, both permanent and seasonal
f. General geologic constraints that will affect selection and operation of solid waste disposal sites
g. Pollution potential and other possible hazards associated with old mine tailing dumps.
h. Other critical factors which may become evident during the course of the study.

The report identified four problem areas. Two problem areas, similar in nature, are listed together as IA and IB. Problem Area IA is Sleeping Ute Mountain in western Montezuma County, and IB is the area of the La Plata Mountains on the Montezuma-La Plata County border. Problem Area II is located in eastern Dolores County. Problem Areas IIIA and 11 IB are both in San Juan County. Problem Area IV is located in eastern Archuleta County. Specifics of these problem areas are provided in the report.
