Whereabouts
Hillsdale Canyon is on the west side of the Paunsaugunt plateau in southern Utah. I collected this specimen there in ~1999. The deformation bands there are in the form of tiny thrusts, causing shortening. I like the delicacy of development of deformation bands expressed in this small rock.
Age & Formation
Straight Cliffs Formation of Upper Cretaceous age, ~70 Ma.
