" This 18-page article contains several maps and diagrams as well as lengthy descriptions of the character and nature of uranium deposits in these rocks. With better developed understanding than many of the earlier USGS reports, this is a must-read article on these significant deposits. There is a good description of roll-front uranium deposits with nice diagrams. The article treats each area separately with several paragraphs to each. Areas discussed include:
Great Divide Basin
Wind River Basin
Shirley Basin
Powder River Basin
Cheyenne Basin
The other article is: Guideline for Archaeological Activities Required under Current Colorado and Federal Law
