21-Apr-2007 -- Diane and I visited this confluence point at about 12:15 PM. As others have noted, it is very close to a paved road. In fact, after we returned to our car we discovered that we could see the rock cairn marking the point while sitting in the passenger compartment.
At any rate, we were traveling East on US Highway 6 from Benton Springs, CA to Tonopah, NV. A turn to the right or south at 38.017671̊ N, 117.998293̊ W WGS84 on a Nevada state highway (shown as number 264 on one mapping software program and as number 773 on another) and a drive of 1.95 km led us to the 38th parallel. We parked and walked east about 30 meters where we found the rock cairn of a previous visitor.
Our GPS marked the point about 2 meters southwest of the cairn.
This is very remote and sparsely populated country. The only improvement in view was the nearby road. The nearby hills and mountains were colorful, but there were no buildings, no people, no evidence of human activity except some old mining scars on the mountains. The vegetation was likewise sparse consisting of very small and widely scattered sagebrush or rabbit brush. The soil was very sandy and an interesting gray color.
It's always magical to see those 10 zeroes. Thanks for getting us out!
