Day 10

Overview of the Cambrian thru Carboniferous in this area, and
comparison to similar rocks we have seen elsewhere. For instance, the
three reddish beds one can use as markers throughout most of the area;
Lancra, San Pedro (equivalent to the Old Red Sandstone), and Riot.
Also, when we see gorse -- in bloom with yellow flowers at this time
of year -- we are looking at the sandstones.
