The Tiny Mine complex is an abandoned gold mine located in Death Valley National Park. According to the park service, its operational years is a bit murky but archeological evidence (found purple glass and hand-finished bottle necks) suggests occupation sometime from the 1880s to about 1920. However a plaque has also been found dated 1945.
The NPS indicates that the mine and site is "three levels of mine workings, an adit on the middle level that had been closed with a tin door, lower-level mill ruins with cement machinery footings, dry-stone masonry foundations, part of a wooden ore bin, and a masonry/cement cistern with a pipe leading toward the mill."
I did not fully explore the site but the adit (horizontal mine entrance) and nearly collapsed building are easily accessible off the main road
The mine is blocked as all are and sure catastrophe awaits those who venture in. As the DVNP website warns "vertical shafts, rotted timbering, hidden collars, bad air, and old cyanide/metal contamination around some mining sites" are all potential hazards of going in
Aside from that this is more of a stop than a destination.
My usual nag for these places - Death Valley is not some kind of hot and dusty Disneyland. It is one of the most extreme environments you will ever find yourself in and it will kill you quickly. The road to the Tiny Mine is an unimproved dirt road / washboard and it gets rough. While the path is not technically challenging it is narrow for a large chunk of the trip. You need water, recovery gear etc to safely venture off the paved roads here. Oh and no cell coverage in many places like this read more
