It is located at the Pine Hills Fire Station, located in a low meadow at the intersection of Engineers Road and Eagle Peak Road (or is it Boulder Creek Rd? I forget).
As of 12:14 am, 10/29. it is still in operation. The temperature is oddly warm though.
I don't know the location of the Julian weather station, but here is the URL:
