MonitoringLocationDescriptionText Split Rock Spring is located in Bear Gulch on the east side of Pinnacles National Monument, CA. Hike southwest from the Moses Spring/High Peaks Trail head at the southwest end of Bear Gulch Road. Near the split between Bear Gulch and High Peaks Trail on the west bank of Bear Creek is a 20foot square, 8.2foot high, concrete, subterranean, spring cistern beneath a flat, grassy clearing. Inflow to the cistern is from a 2inch diameter pipe near the cistern ceiling on the south side of the concrete cistern. Water flows from the cistern at a sump at the base of the northern cistern wall. National Park Service records indicate that cistern inflow is piped from an upslope spring and french drain. The Civilian Conservation Corps built the cistern in the 1930s to store water for NPS supply and fire fighting. The USGS Site ID is 362840121110801and is named SPLIT ROCK SPRING.
