springs. The middle and lower springs have been developed with concrete soaking tubs and showers are present. The upper spring is in an undeveloped natural state. In late 2005, seismic activity disturbed the flow of water to the lower springs. The only functional section remaining after that was the middle springs. However, the flow appears to be returning to the lower springs. As of early 2007, flow is estimated to be about 50% of what it was before the earthquake, and is increasing, making both springs functional. Military use Low-flying jet aircraft have long been common in the valley. The airspace over the valley is part of the US military's vast R-2508 Special Use Airspace complex. The Saline Military operations area (MOA) covers the entire valley south to Hunter Mountain from 200' AGL up to FL180 with an ATCAA located over the same area extending from FL180 up to FL600. The airspace is used by military aircraft primarily from Nellis AFB, Edwards AFB, NAWS China Lake, and NAS Lemoore for high and low altitude mission training. Military aircraft utilize radio communications on either 256.8 MHz or 123.95 MHz while operating in the Saline MOA; however, military aircraft throughout the R-2508 complex often use 315.9 MHz when conducting low altitude operations below 1500' AGL. In December 2003, Edwards Air Force Base completed an environmental assessment for proposed construction and operation of a radar system and microwave repeater facility in the valley.
