I was not driving, but we were on highway 15 North of
San Bernardio, California in what some call "Cajon Pass",
if memory serves me correctly.
It was like out of no where comes this small mountain
made out of solid rock. The picture does not do it justice,
but you get the idea.
I was told it is called "Mormon Rock".
Put any name you want on it, but it sure is
a stand out.
