David Croyle#PhotoOfTheDay is an aisle of the old Map Room at the USGS West Coast Headquarters in Menlo Park, California. This place was like a temple to topographic maps, with some very old handmade benchmark disks on display too.
Sadly, it's been gone for a while now. We did an interview with the head of mapping there (I was helping to make a benchmarking video) and he explained that he had none of his people left that did actual field work. :(
