When it comes to history one has to be corrected. On Sept 9th of this year, a portion of Table Mountain, which was believed by many not to be named, finally got a name...East Table Mountain. I previously wrote this; "The entire mountain, which now includes the newly designate East Table Mountian, is in the San Bernardino National Forest...but it has be administrated (or managed) by the ANF for many, many decades."
I had a vapor lock and said something that needs to be cerified (and thanks to Wrightwood for pointing it out).
The entire mountain is not in the San Bernardino Forest. Being a former Forest Service employee, I tend to go by forest service maps more than anything else. According to a 1964 USFS map, the Angeles National Forest (ANF) boundary appeared to be at Table Mountain Campground, which is in the area of present day Mt High North. From this area, the line extended east only one and one half section, presumably to the property of present day JPL and the observatory. Anything east of this location appeared to be in the San Bernardino National Forest (SBNF).
History side note: This 1882 map of what was later called Big Pines and Wrightwood, identifes present day Table Mountain as "Divide to the Mojave Desert and Sweartout Canon; apparently, someone couldn't spell Swarthout correctly.
The 1985 map from the USFS shows a better location of the boundary of ANF and SBNF as strictly following the Los Angeles and San Bernardino county lines as the line extended north over Table Mountain. (it travels a pretty good line northwest from present day Flume Canyon...and west of section 31) The country line extends southeast to northwest...passing through the general area of the Ford Observatory and old Mircowave Station on top of the ridge. The boundary line of the ANF and SBNF is well west of the location that has been recently named East Table Mt...so East Table Mountain is in the San Bernardino Nation Forest, while anything else a little more west on the ridge is not. The lonely ridge, overlooking Wrightwood from the south, and the Mohave Desert floor to the north...sits quietly on two forests, but only managed by one...the Angeles National Forest. It has been managed by ANF for many, many decades.
