Buchner, E., and T. Kenkmann, 2008, Upheaval Dome, Utah, USA:
Impact origin confirmed. Geology. vol.36, no. 3, pp. 227-230.

In part, this abstract stated:

“In this study, we document, for the first time, shocked
quartz grains from this crater in sandstones of the
Jurassic Kayenta Formation. The investigated grains
contain multiple sets of decorated planar deformation
features. ... The shocked quartz grains were found in
the periphery of the central uplift in the northeastern
sector of the crater, which most likely represents the
cross range crater sector.”
