Robert Kirkham, a geologist with the Colorado Geological Survey [editor’s note: and also a member of RMAG], received the Colorado Scientific Society Past President’s Award for the Best Paper of 1999. Bob’s paper, “Dissolution of evaporite causes widespread active collapse in west-central Colorado” was delivered to the society in April.
Bob Kirkham and other Colorado Geological Survey staff members began a geological mapping program in the Glenwood Springs area in 1993. As the mapping progressed, various odd geological structures were noted but their origin was poorly understood.
While working on the geological map of the Carbondale 7.5 minute quadrangle, Kirkham discovered additional evidence that led to the formulation of a theory involving the collapse of a large area due to the dissolution and flowage of beds of evaporite.
Continued work in the area by other Colorado Geological Survey and U.S. Geological Survey scientists corroborated, expanded and clarified Kirkham’s original hypothesis. The paper presented at the Colorado scientific Society meeting was based upon the cooperative work of the scientists from both the state and federal geological surveys.
