Bobcat Pit, Arizona

Bobcat Pit is an Arizona sinkhole on private property — get permission from the landowner before visiting. The landowner was very generous in explaining the region's history. The basalt surface collapsed onto the redwall limestone where a cavity was dissolved underneath, forming this sinkhole.

We found some passage but the sink seeps all of the water taken from this sinkhole — substantial dried silt to dig through. Interesting to see the basalt layers from ancient lava beds, and even more interesting to see the wildlife that made a habitat within this karst feature.
