escarpment passes under, and the upper begins to come to the 
front. At camp it is about 800 feet to the top of the face 
of the upper escarpement. Fortunately we encamped near some 
interesting ruins. About one mile below the two story house 
and just u$der the curious house with the 16 windows. 7/hen I 
passed here before I made a sketch of the group and made the
