These kinds of holes are found all over the Arizona and California deserts.
They're vertical mine shafts and can be quite dangerous.
I walked around a 4'-5' tall bush and if I hadn't been watching I would have walked right into this one.
Sorry there's nothing to scale it against, but the size is fairly common.
Enough room for one guy to dig and it looks to be about 100' deep.
Since it's had a long time to erode due to monsoon rains and other storms that cross the desert, the sides are not as smooth and clean as the Russian
holes which are apparently much younger.
The hole shown in the photo is probably a hundred years old if the known to be 100 year old corrugated tin/sod houses in the general area are any
indication.
It's not a well shaft since all these old houses are fairly close to a year-round stream.
There is an old collapsed mine building/house that's collapsed about 100' away from the hole.
The stream is perhaps 100'- 200' from the house and down a small hillock a little ways.
You can find these old mine shafts in areas of flat desert, in the foothills and in the mountains.
They are a hazard to say the least and it's not uncommon for folks exploring the desert to fall into them.
Sometimes their dirt bike, quad or full size Jeep goes in as well.
One of these vertical mine shafts in the general area is 1600' deep and big enough to swallow a pickup.
If you look to the left of the gentleman in the photo below you'll see a horizontal mine shaft.
These are usually a little bigger diameter-wise than the vertical shafts, but they can go back into the mountain quite a way.
We believe the mine shaft in this area was a Turquoise mine and it's not too far from a big copper mine that's still in operation.
Most times, turquoise is found in copper mining areas.
Along with aluminum which is part of the process nature follows in the creation of turquoise.
The vertical shaft mine shown above is more than likely a gold mine since it's close to an area with several gold mines.
Shown in this photo - just over the authors left shoulder - is a larger gold mine, long abandoned, but most of the equipment is still there.
And . . . just for the heck of it, some of the tiny wildflowers that grow in the desert late fall, early spring.
The shiny, square object shown with the flowers is my rock hammer which is also shown in my avatar.
It would be interesting to know the geological make-up of the Russian forest area where the deep vertical shafts are being found.
It's very conceivable that they could be nothing more than an exploratory shaft sunk to follow a vein of gold or other valuable material.
Especially so when you consider the vertical mine shafts found in the deserts of California and Arizona.
Other Western states that saw a lot of mining activity in times past probably hold the same types of mine shafts and are equally dangerous for people
in those states.
I'm not discounting the ET factor, but looking from here and what my past experience has been, my vote is the holes are simply exploratory mine
shafts....
