if a sound and viable plan of development is to be devised for the

area. This report describes some of the adverse geologic conditions

of the area, and evaluates some of the hazards in terms of possible

area development.

Under the legislative charge to the Colorado Geological Survey

to "determine areas of geologic hazard that could affect the safety

of or cause economic loss to the citizens of Colorado," and "to eval-

uate the physical features of Colorado with reference to present and

potential human and animal use~" an extensive reconnaissance investi-

gation of the Marble area has been performed by staff members of the

Colorado Geological Survey. The investigation, to date, has consisted

of a study of the available historical and geologic records of the

Marble area, photogeologic evaluations, and reconnaissance field work

in the area. The investigation to the present time has included 12

man-days of field work. Approximately 20 days of office time were

spent in detailed photogeologic studies, literature research, inter-

pretation of the collected data, and preparation of the report.
