This appears to be the remains of a long unused mine.  Steep walls rise a
hundred feet or more, with a large patchwork of fabric strung across the
top.  This arrangement keeps all the rain and wind out of the canyon, making
it quite comfortable.  The main road is just to the north, while a rather
large tent is to the east.  The canyon continues to southeast.
