Flew to 5 miles east of Half Dome in Yosemite National Park. I started with 30 gallons of water in wings and 3.5 litter in tail, but dumped it for 25 sec on my way to the south. The could street ended around USMC, and there were only step stone clouds, but lifts were still good (7 to 10 kts) along the same line as the cloud street. There was a soft spot west of South Lake Tahoe airport which cost me some time. After coming back to Truckee, I tried to go north, but clouds started to dissipate, and couldn't make it. There was a big blue gap north of Sierraville for about 20 miles. Many people who started much earlier than me went as north as Mt Lassen.
