I took this on the road just north of Gillette Wyoming. It is in the Little Powder River Valley where that 6 foot across river (currently) eroded all this Alluvial Fan Deposit away…it’s actually traceable way back to the Big Horn Mountains 100 miles away. (Tullock Formation of Tertiary age).
This is located just north of the coal measures being mined at the surface.
When the geology is traced back, the undertanding that the hills on the other side of this valley connect layer by layer with this side. Lot of work for such a little river🤔
Anybody notice the small herd of antelope on the lower left??
