Rancor cave is a new Nevada cave that was discovered on a ridge walk in the Mormon Range. 

This cave has a interesting entrance with a complete skeleton of a bighorn sheep at the entrance that was eaten by something...

Indeed the tall narrow entrance with the big horn skeleton at the entrance made for a warming welcome when I walked into the cave. 

The passage has a nice red color to the walls and ceiling.  I wish I brought my proper camera to photograph the passages but I will be returning for more.
