Although their are dozens of mines deep in the El Dorado Hills their are some naturally formed dens like this one. You have to be careful approaching them they are places for coyotes and mountain lions to rest their heads at. I know that Haunted Highway tried to in someway suggest hell hounds are cryptid but truth be told if that were the case we would have discovered them by now especially with the amount of friends I have known to four wheel back here. It is what it is a lions den!
