These are updates about the study of
the suspected impact crater site at the Black Rock Desert in Nevada.
So far we've found clues that indicate an ancient impact crater
of at least 30 miles in diameter
may be part of the underlying geology of the Black Rock Desert.
But glacial, lake and stream erosion as well as faulting have
erased perhaps 80% of it.
Now the Black Rock playa runs through it.
Parts of the Black Rock Range, Calico Range and Kamma Mountains may be
among the few remaining visible parts.
So you have to look carefully - but we find more clues
with every visit we make to the area.
