Man's efforts, spanning at least five thousand years, don't amount to much out here. Bryce and I explore the main chamber, which is about 60 feet long and wide, and 75 feet tall. Cave swallows investigate our presence, defeating complete silence by slicing the air above us. I see no evidence of bats. If there are any bats here, they are likely sleeping as they tend to do.
Smaller chambers pock the hillside east of the main chamber and appear back filled.
Perhaps they were once passages to underground caves now sealed by earthquakes and time. A metal box erected by a governmental agency stands just inside the main cave, strangely out of place. Perhaps it held a guest registry at one time. I get the distinct feeling there aren't many visitors here these days, but it's easy to imagine the cave bustling with activity at one time, and bustle it did. In the late 1940's and early 1950's, archeologists excavating Bat Cave unearthed an abundance of man-made materials.
