Forestation is not the same as topography.
I have not evaluated the orientation of the ground photography and have insufficient detailed information to do so, as data recording the likely large changes in usage over time of whatever base this is are not in ready supply ( to me at least) The Stewart AFB suggestion comes from Americans more familiar with their country than I am. So what they do say regarding likely location seems more reasoned than, for example, suggesting a fairly arid scrub-land base in Utah, situated between high mountains and a large salt lake.
Purely from an assessment of the aircraft on site, I am sure it is post early 1955, ( the F100C) and if it is a Palen's first Curtis Pusher ( as the OP on FB has independently suggested) then that puts it as likely to be pre-1958 ,possibly backed up the presence of the SPADXIII and Avro 504.
Do note that I hold no absolute opinion yet on that Bleriot's provenance.
Lets see what develops.
