Fort Pike is surrounded by masonry walls on its landward side...these weren't so much walls intended to keep out a foe, but rather to act as an outer defensive position. These walls are in pretty sad shape today, but this, the covered way, has been kept most tidy and impressive. To the left is the lil' Ranger Station...and perhaps that red sign explains why there was no litter in Fort Pike at the time of my visit: No pets, food or drink beyond this point! Discarded beverage bottles and/or cups are by far the number one form of detritus that I've seen in my starfort travels.
