We found this on the National Park Service’s Morning Report. So many questions.

Two Rescued From Mine Blocked By Rattlesnake
A man and a boy who entered Ore Car Mine off North Shore Road at Lake Mead National Recreation Area last Friday were unable to exit due to a rattlesnake blocking their path and called for help.
Rangers responded along with personnel from BLM, Henderson FD and Las Vegas Metro PD SAR. The pair were successfully extricated.
