DSC_1263

2ce a year, the sun lines up with the angle of the tunnels. Figuring out the day involved measuring the angle on the map and checking that against tables from the Naval Observatory. My battery died just as i arrived, but it wasn't as spectacular as i'd hoped. Fun to find and check out though.
