Old Problem List is a bouldering area in Long Ridge Open Space Preserve, in California's Regional Agency Land, about a mile from Stoner Cave and Devil's Canyon. It sits among a cluster of climbing areas, with Aquarian Valley just 0.1 mile away. The preserve's weather station at Skyline Ridge, about 2 miles off, records typical averages that make summer the most comfortable time to visit. July and August highs average around 81°F, with only about one wet day a month, while winter months see highs in the mid-50s and rain on roughly 14 days. That station sits at 2,270 feet, so conditions on the boulders may differ slightly. The area has six bouldering problems, all rated on the V scale, with grades from V2 to V7. Silicon Bond is V6+, and Red Eye is V7. Boulderers can also head to Stoner Cave and Devil's Canyon, both within a tenth of a mile, or take a short hike on Peter's Creek Falls Trail, 0.3 mile away.
