On 7-8-2014: Hiked Old Greyback via Vivian Creek trail head. Very nice hike, I recommend it. Trail is good generally. We found easily gotten water at Vivian Creek camping spot about 1200 feet up, where the trail crossed the small stream. More importantly, we found easily gotten water near High Creek about half-way up the mountain where trail crosses stream at about 9200 feet; however, this tiny stream might go dry later in the summer. Note that the last two years have been very dry in this area. About 67 degrees at trail head at 7 AM.
This is a unique peak, as it is the 7th biggest (official prominence) mountain in the Lower 48 and you look across at the 6th biggest mountain in the Lower 48, San Jacinto, with a 10,000-foot deep 'valley' in-between. You can't do this anywhere else in the 48 States except White Mtn looking across to the California High Sierra. More impressive to me than the Grand Canyon and the Snake River Canyon. I have seen all those sights.
