Lynn Hill Memorial Boulder is a bouldering area in Joshua Tree National Park in California, managed by the National Park Service. It sits among a cluster of climbing spots, with King Dome - East Face, King Dome Area and Split Boulder all about 0.1 mile away. The area is a memorial to the climber Lynn Hill, and its routes are all boulders, ranging from V0 to V4 on the V scale. 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 1,050 feet lower than the boulders, so temperatures on the rock run cooler.
