About 1 mile ESE of gate 700 is an excavation of some kind with what appears to be couple of underground openings. Over the years the amount of scrapping in this area has changed, and there does not seem to be a beaten path into these openings. Any ideas? This spot doesn't have a label that I can find.
Thanks
