The Blob is a climbing area in Joshua Tree National Park in California, managed by the National Park Service. It sits among a cluster of other climbing spots, including the Scatterbrain Area, the West Face and the Southeast Face of The Blob, and Hensel Boulder, all within about a tenth of a mile. The area is close to Hidden Valley Trailhead and Echo T Trailhead, both about half a mile away, and to Barker Dam Trail at roughly 0.7 miles. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station in Yucca Valley show April highs around 73°F and October highs around 80°F, while July and August average about 96°F. That station sits roughly 1,000 feet lower than the park, so temperatures at the Blob run cooler. The area has four routes, with grades ranging from 5.6 to 5.13a. Three are trad routes, and one, The Persian Room, is a sport route. The hardest of the trad routes is Surrealistic Pillar at 5.10b/c, and the hardest overall is The Persian Room at 5.13a. Sheep Pass Group campground is about 3 miles away for anyone planning an overnight stay.
