Brief report:
Saturday, Dec 16th 2006: Road was blocked at the intersection of Patriarch Grove road with White Mountain Road. Slept inside Tina's truck. Windy with 6" to 8" of snow overnight.
Sunday, Dec 17th 2006: It was 1 deg F around 6:30am. Started hiking at 8:30am (3 deg F) from Patriarch Grove intersection. Took a cross-country route passing north of Sheep Mountain. Got to the regular summer locked-gate trailhead around 11:00am. Rested there for 15 minutes. Continued on and reached the Barcroft Research Station (12,500') an hour later. Decided to call it a day here. Back to Tina's truck by 3:20pm (still 3 deg F at 3:30pm). Drove in 4WD out with 6-8" of fresh snow with the occasional 1-foot snow spin drift. Found that the USFS locked us at the Sierra View gate; luckly, they used a bungee cord to lock the gate and not a padlock. Closed call! So, currently, White Mtn Road is locked at Sierra View. Tina's TR.
