the seller adds:
"
This would be in Sycamore Canyon in the local San Gabriel Mountains just above Pasadena here in Los Angeles County
and the area was very popular with hunting lodge places and recreation hiking and camping with Mt Lowe and Mt Wilson
and so many other trails locations and such. These places came and went through the decades with some wiped out due to a fire
or flood or just being abandoned."
The photographer is identified on the front and back as A. E. Arnold 111 North Bonnie Avenue Pasadena Calif
