Access:  From the intersection of US Highway 95 (US 95) and Highway 373, head west on US 95 about 3.8 miles and turn right onto an unnamed dirt road.  There is an unlocked gate at the edge of the US 95 right-of-way. Proceed northeast along the dirt road about 225 ft and turn right.  Continue about 400 ft along the unnamed dirt road to the cleared well pad area.  The well is located on the north end of the pad.

Purpose
- Water Resource Conditions in the Amargosa Desert:  
NC-GWE-2P is one of seven boreholes and monitoring wells to:
1) collect baseline flow and chemical data south and west of the Nevada Nuclear Security Site, and 2) determine head relationships near the Gravity fault to help determine the role of the Gravity fault in restricting or facilitating groundwater flow in the Amargosa Valley.
