Narrative and photographs

G 308 still has us stymied! It should be as simple a find as the others in this area: concrete monuments that project enough to be visible in this desert landscape for tens of meters around, often still accompanied by their original witness posts. But we had no luck at all with this one. We searched at both the NGS and USGS coordinates (less than 100 feet apart in this case) and wandered around the entire area, surprised that we were unable to find anything. Referring to the description, we noticed that (assuming it’s correct) we should have been searching much closer to the road, but that area yielded nothing either. We’ll have to take another look when we’re back in this area. I can’t think of a good reason why this mark would be gone, so it’s probably still here, and either we just happened to miss it, or the coordinates and description are off enough that we were looking in the wrong spot.
