The following report covers a chemical study that was made of the Salt Wash member of the Morrison formation of Jurassic age in the Jo Dandy area, Montrose County, Colorado in 1954. The chemical study was made to investigate the distribution of elements in the host rocks with emphasis on the pattern of variation as related to the position of known ore bodies, and to determine average concentrations of some of the elements in the major rock types.

Summarizing the data on the uranium-vanadium deposits of the Bull Canyon area in Montrose and San Miguel Counties, Colorado.

The following document contains the 17 figures in relation to the report, Environment of Uranium Deposition in the Bull Canyon Area, Southwestern Colorado.

A study made of the joint patterns in four different formations exposed in Bull Canyon, and of favorable and unfavorable ground in the upper ore-bearing sandstone unit of the Salt Was member of the Jurassic Morrison formation.

This report sumarizes the results of the US geological survey exploration in the Bull Canyon district from October 1955 to April 1956

From introduction: This report summarizes some of the results of U. S. Geological Survey investigations in the Club Mesa area and presents a compilation of available geologic data that would be helpful in future exploration. Detailed geologic logs of U. S. Geological Survey holes drilled in the Club Mesa area on public land that is no longer withdrawn from mineral entry are on open file for public inspection in the U. S.
