Fault A
Normal faults offset the rocks visible in this road cut near the old community of Nugget in the Tunp Range west of Kemmerer, Lincoln County, Wyoming. The red beds on the right are calcareous mudstones which are part of the Upper Triassic Ankareh Formation. To the center and left of the photo, the purple to red beds of siltstone and sandstone also belong to the Upper Triassic Ankareh Formation. The tan interbeds on the left are indurated sandstone (quartzite). The tan to buff colored rock on the left above the red beds are the lower beds of the Triassic/Jurassic Nugget sandstone. Nearby these sandstone beds become massive, crossbedded, ridge-formers.
