Rogaining 5:08:19 [2] 23.6 mi (13:04 / mi) +1485m 10:56 / mi
Sanborn Hostel to Big Basin HQ via San Andreas, Skyline, Saratoga Gap, Travertine Springs, Saratoga Toll Road, (unnamed connector on a private easement), and Skyline-to-the-Sea trails. Had 1:20,000 TopoZone USGS for the whole thing (without any of the trails), and tried to maintain constant, but not continuous, contact—count reentrants and stuff. Frequently frustrated—the USGS photogrammetrist must have had no bigger luck with the redwoods than the Helgesen dude who made the Big Basin base. The low point came on the (unnamed connector) when I was going exactly opposite to where I thought I was going on the map. Also had an awful time at the segment where Skyline-to-the-Sea follows CA 236—could not even track the bends in the highway.
Climb is (575 +/– 5) m to Castle Rock parking lot (4.2 mi); after that, my best guess from the USGS, the official park Castle Rock map (nice—shows most bends in trails and stuff), and Sempervirens Big Basin map—not nice. Mileage is from park trail markers—will adjust if I get better info.
Note
The original plan was to camp at Big Basin for the night. Then it got revised to push on to the Ocean in the afternoon, but as I was about an hour behind the plan, revised back.
It was not a very enjoyable stay at Big Basin. Smoke filled the basin; hard to tell whether most of it was from a controlled burn or from the woodfires in the packed campgrounds. Millions of people in the campgrounds, but met less than 10 on the trail in all of BBRSP. Go figure. Also, the park's store sold me a $5.99 + CA tax ham sandwich, thoroughly consumed by mold. Yuck. At least the shower water was hot.
