Update: As of today 3/1/10, the road is open through Big Tujunga. Closed gate will be encountered at SnowCrest. Looked like they were plowing beyond that, so maybe it'll be open to Islip Saddle soon. Snow level starts at around Newcombs Ranch.
This ain't my neck of the woods, but this hwy leads to Horse Flats bouldering area, Pacifico, Tunnel Crags, Williamson Rock. How far can I get? Is it open to Horse Flats? I heard the forest was all closed due to the fire last year, and the road is jacked due to weather.
In case anyone's interested...Angeles Crest Highway is OPEN all the way THROUGH from Tujunga to Wrightwood. We were up there today as far as Dawson Saddle Elevation 7901 feet. Still lots of snow for skiing, right down to the highway!
