This one from Tim Hanson. The caption from the photos (286747. 286748, 286749, 286750) reads:
"Butte County. Panorama looking SW, S. SE and E from Neal Road. Note Juniperus californica in ravine. Woodland grass type of blue oak and digger pines with occasional Ceanothus cuneatus, Arctostaphylos manzanita and Rhus diversiloba."
There is still California juniper in the ravine, including far right of the new photo, which is uncommon in Butte County. The rare Monardella venosa grows in patches of dense clay soil in the flats of the canyon. The Wieslander picture was taken on 6/24/1933 and his picture was taken on 5/3/2011.
