I got this info from SummitPost regarding White Mountain:
Just passing along information....having the gate open cuts a lot of distance off the hike to White Mountain.
The University of California White Mountain Research Station will hold its annual Open Gate Day on Sunday, September 2. The gate to the Barcroft Research Lab will open at 6:30am for those wishing to ascend 14,246 ft White Mountain Peak. Hikers may park at the Barcroft facility, however, the Barcroft facility WILL NOT be opened to the public on this day and we ask that people do not disturb the staff or researchers at the station. Friends of White Mountain will park cars and sell souvenirs. For more information, call (760)873-4344
