Lower Indian Rock is a bouldering area in Sanborn County Park, on county land in California. It sits within a cluster of climbing spots, with Indian Rock and Hash Rock both about 0.1 mile away, and the Sanborn County Park (Indian Rock Side) climbing area right beside it. The park's Indian Rock Side is the closest neighbor, and the Castle Rock Trail starts about 0.3 mile off. The area is a bouldering destination, with 17 routes all rated on the V scale. The grades run from V0-1 up to V8-, with the median at V4. Among the named routes are The Scoop (V0-1), Left Hand Indian Man (V4) and Flow Juggler (V8-), the latter a first ascent by Barry Bates. Summer is the driest and warmest stretch. Typical averages from a nearby weather station show July and August highs around 81°F with only about one wet day a month, while winter brings highs in the mid-50s and rain on roughly 14 to 15 days a month. That station sits about 700 feet lower than the park, so temperatures at the boulders run cooler.
