The Pitchfork formation is here defined as the lowest series of beds in the southeastern part of the Absaroka Range, Wyoming. The Pitchfork formation consists largely of detrital rocks--sandstones, siltstones, ... Park-Absaroka volcanic province. The thickness of the Pitchfork formation ranges from about 200 to about 1, ...

Several regional correlations of the Pitchfork formation and underlying beds are suggested. The Pitchfork ...
