Death Valley history is filled with tales of snowflake caves, lost mines, and tourist eating mutants.
It's very common for prospectors to lose their mines in Death Valley and it's not unusual to overhear a crusty old miner walk up to a Park Ranger and say "I lost my Mine"!

 The directions to this fabled lost mine cannot found on any map, but stories about gun fights occurring here and its rich ore may still be found in books. The Lost Death Valley Mine is described as being massive and cavernous, consisting of many adits and shafts.
