OF THE SAN PEDRO RIVER
The strip map above focuses
attention on the location of The Narrows of the San
Pedro River -- where a geological separation of south from
north crosses the river. To the West are uplands leading
to Wildhorse Mountain in the Little Rincons; to the East
are the Johnny Lyon Hills. Both of these uplands are composed
of the same type of intrusive Proterozoic-age rocks. The
Cascabel Road passes right by the Narrows at this point.
