About this collection

BLM manages oil shale development in Colorado, Utah, and Wyoming. This collection includes contract reports and data - in particular, environmental baseline data - from the Colorado C-a and C-b tracts and the Utah U-a and U-b tracts leased for oil shale mining. The reports were produced in the 1970s and early 1980s and are from the Oil Shale Project Office which closed in 1987.
