at 114 degrees David Harris and I set out to find a sinkhole in the desert which had apparent features to be at least a sinkhole. 

Indeed once we got there, we confirmed that there is a sinkhole so we set out to located and identify what this potential cave could be. 

We made it the the entrance and it was indeed a sinkhole with shade!!! Lots of shade and much needed to get out of the heat.

We get into the sink and there appears to be a room just inside the bottom of the sinkhole. We get in there and immediately we start to hear a loud rattle. A grand canyon rattle snake appears and looks quite pissed of our presence.

The passage appeared to start to close up but the snake blocked continuing to look further into the small area where the passage could go. This is why we called this sink...
