Today we used all the stratigraphy we have been compiling in the Whitehall area as a comparison to some new stratigraphy to the south-west of here. We ended up learning a decent bit about the regional geology of the MT area. It appears that during Jurassic times there was belt uplift (belt island) then immediately afterwords in the Cretaceous there is evidence of an active foreland basin forming over the same area, drawing its main sediment sources from the mountain ranges to the west of the Tobacco Roots where camp is located.
We spent all day working down near the Pioneer Range, a likely source of sediment for the foreland basin, mapping a thrust sheet overtopping an anticline structure.
I managed to go all day without seeing or hearing a rattlesnake. The snakes were probably all really trying hide out today because it was HOT. The sun was really beating on everything today, even the cows I saw out in the field were trying their best to stay in the shade.
We had a great dinner today. BBQ chicken, corn on the cob, rolls, rice with black beans, and cherry pie for dessert.
I have a big all day project to do tomorrow; so, I am going to cut the post short.
