There is a crater near highway 6 about 60 miles from Basecamp. The USGS topo map indicates this is a meteor crater, though this is disputed in the article:
"A Possible Meteorite Crater near Duckwater, Nye County, Nevada" by John S. Rinehart and C. T. Elvey, "Popular Astronomy", 1951, Volume 59, pages 209-211.
[Thanks to Tom Mahood for finding this reference.] The article traces the first documentation of the crater in the August 4, 1936 issue of "The Tonopah Daily Times Bonanza" in an article by C.C. Boak. Mr. Boak spoke to Ralph Irwin, a resident of Duckwater, who encouraged that the crater be examined. Boak, who was a mining engineer and amateur mineralogist, looked for possible explanations regarding the creation of the crater that were not related to a falling meteorite. Examining the geology of the area, Boak could not find any reason for the crater to exist, and deduced it was formed by a meteorite. Irwin related to Boak a legend told to him by an Indian whose ancestors saw "a great ball of fire come rushing from the sky." It is interesting that Irwin heard the Indian story first then stumbled upon the crater later. Irwin and his brother had dug a shaft about 25ft in depth in the early 1920's into the crater looking for the meteorite, finding nothing but sedimentary deposits, since rain runoff flows into the crater. No meteorite has been found in the crater or the surrounding area. Rinehart and Elvey attempted to find bits of the meteorite by sifting through the soil with magnets.
There is some speculation that this crater is a limestone sink. [Look for Duckwater on this page: http://www.netppl.fi/~jarmom/geo/imp/possible.htm ]
The photo on the right is from the Terraserver, with south facing upwards. You can clearly see how runoff flows into the crater. The photo on the left was taken from the north edge of the crater looking SSW. Check out http://www.barringercrater.com/lite/meteorite/crater.htm for various methods to determine if a crater was formed by a meteor.
This may be the remnants of the Irwin brothers excavation, though obviously the hole isn't 25ft deep. The side walls are smooth, so perhaps the soil layering was studied. Meteorite craters will have a soil layering inverted from the surrounding soil since the meteorite kicks up the local soil into the air, where it then resettles in the crater.
This map was done using the Black Rock gas station as a reference point. It wouldn't hurt to fill up before making the trip, even it you don't need the fuel. [It is a good idea to support these out of the way gas stations so they can stay in business because someday you might really need the fuel.] You could show the store operator a copy of this webpage just for yucks, showing that Black Rock on the map, well at least this map.
Check out http://www.usgs.gov/public/press/public_affairs/press_releases/pr372m.html for an interesting press release regarding a much larger meteorite landing near Alamo, Nv.
There is another meteorite in nearby Quinn Canyon. See http://research.amnh.org/earthplan/collects/meteorqs.htm for further details.
I found this information from a now defunct website but cached on google:
Quartz Mountain.............................37'12' N., 116'42' W. Nye County, Nevada, U.S.A. Found 1935 Iron. Octahedrite, medium (1.1mm) (IIIA). A mass of 4832 grams was found. Analysis, 7.85 %Ni, 18.6 ppm.Ga, 36 ppm.Ge, 4.2 ppm.Ir. Kamacite shocked to epsilon structure .
Quinn Canyon................................38'5' N., 115'32' W. Nye County, Nevada, U.S.A. Found 1908 Iron. Octahedrite, medium (1.1mm) (IIIA). A mass of 1450kg was found 90 miles east of Tonopah. It is possibly part of the Nevada meteor of 1894 (February 1, 2200hrs). Too weathered to be a recent fall, includes Tonopah. Analysis, 8.40 %Ni, 20.9 ppm.Ga, 41.5 ppm.Ge, 0.58 ppm.Ir .
