For another day-trip, we went out to the Ririe Reservoir dugway again. I managed to make it home without any significant ash fragments in my eye. These photos show more of the detail of the Kilgore tuff deposits. As seen in the photo above, these are very thick ash deposits.
We used Jacob's staffs to measure thickness of the different ash deposits.
So much pumice!
Another contact further up.
An "intraclast" (the brownish clast just below the pen). Clasts of the underlying bed are included in the subsequent depositional unit, in this case, a "rip up" clast.
