Colony Shale Oil Project

The Colony oil shale development site in August 1973.

Colony Shale Oil Project was an oil shale development project at the Piceance Basin near Parachute Creek, Colorado. The project consisted of an oil shale mine and pilot-scale shale oil plant, which used the TOSCO II retorting technology, developed by Tosco Corporation. Over time the project was developed by a consortium of different companies until it was terminated by Exxon on 2 May 1982 a day which is known amongst locals as "Black Sunday".[1][2][3]
