Since several images lately were of nature imitating life, here?s one that
my lady friend thought looked like a ram?s head poking out of the Mehrton
formation north of Lake Tahoe.

Mehrten Formation
During Miocene time, volcanic material continued to be ejected from
volcanic centers along the crest of the Sierra. Eventually, the
central
and northern Sierra Nevada was covered with a thick blanket of
andesitic volcanic rocks known as the Mehrten Formation. These rocks
include andesite conglomerates, welded tuffs, lava flows and lahars.
