Battle Mountain        40.66813°N, 117.18913°W
Humboldt County, Nevada, USA
Fell: 2012 Aug 22 06:17 (UTC)
Classification: Ordinary chondrite (L6)
History: The fall was observed in weather radar imagery from the US NEXRAD radar network, operated by the US National Weather Service. The discovery and analysis was done by Dr. Marc Fries, Galactic Analytics LLC. The KLRX radar in Elko, Nevada, is approximately 33 km from the fall site and recorded the fall in eight radar sweeps between 0619.26 UTC and 0621.03 UTC. This time span of 97 s is short compared to other meteorite falls observed by radar. This could be a result of meteorite production by a single, large breakup event, by relatively little fragmentation, or a combination of the two factors. The first stone was found on September 1, 2012, 10:50 AM (PDT) by Robert Verish; it weighs 19.25 g. As of 3 Oct 2012, at least 23 stones with a total mass of ~2.9 kg have been reported.
Physical characteristics: Most stones have a similar appearance, with a blocky shape where corners are not well-rounded; where orientation is exhibited, it is poorly developed. Regmaglypts are smaller than thumb-sized. Fusion-crust is uniformly distributed but thin, and on some sides of several stones displays a brownish patina on an otherwise uniformly black surface.
Petrography: (Alan Rubin, UCLA): The stone is recrystallized with 50-μm-size plagioclase grains. Olivine grains exhibit weak mosaicism; many chromite grains are extensively fractured. Troilite grains commonly polycrystalline. There has been localized melting of metal and sulfide. Several grains of metallic Cu occur inside metal at the boundaries of small (apparently melted) irregularly shaped troilite grains.
Geochemistry: Ca-pyroxene Fs7.8Wo43.7 (n=2); low-Ca pyroxene Fs19.8±0.2Wo1.3±0.3% (n=22)
Classification: Ordinary Chondrite (L6), grains are extensively fractured – moderately shocked (S4), unweathered (W0).
Specimens: An endcut of the 19.25 g stone found Sept. 1 was thin-sectioned and classified by UCLA. A slice from this stone of 3.85 g (20%) is held by UCLA. Another stone (56.5 g) was found in 3 pieces and is held by the finder, Martin Cunningham, Battle Mountain, Nevada. The finder donated one of the 3 pieces to UCLAÂ which makes a total of 46 g type specimen. The second find from this fall (954 g) is held by Robert Ward, who purchased it from the finder. This stone is the largest mass recovered to date.

Battle Mountain fell Aug. 22, 2012. Bob Verish and Moni found the first stone on Sept 1, 2012. Word spread fast and I got on a plane as quick as I could. I made 2 trips to Battle Mountain and found 2 meteorites on each trip. The first outing I teamed up with Scott Johnson and I was fortunate to find one on my first day! BaM 006. I found it on my anniversary, Sept 8. I found another a few days later, 38 grams. After 10 days I went home to re group and rest. On my second trip I teamed up with Keith Jenkerson for another 10 days and I found 2 more stones.
My first Battle Mountain find.



Scott was happy too!

My second find 38 grams.


Taking another selfie! One thing about meteorite hunting, there is lots of time alone.

My 3rd find

236 grams, the last one I found, now part of the ASU collection and on display.

This place is big. To put things into some perspective, the yellow trees in the bottom are about 70+ feet tall!

Marty Cunningham, a local guy, finds a meteorite!


There were tiny trout in this stream. The interesting thing is that most of the stream was not above ground at this time of year. When startled, the trout would swim underground!

Christopher Cottingham found an 1800 gram stone 300 yards from where Scott and I camped for several days! Once again, if your name isn’t on it, you’re not going to find it. Christopher and his dad Michael were kind enough to take Keith and I to the find location and let us drag our magnets through the impact pit. We collected a few grams of fragments each.

Christopher’s meteorite was broken in half. Here the two pieces are held together.

I think this is one of Robert Wards finds.


Greg Hupe getting the most out of his clothes!

Is this the first find, Bob? Someone let me know.

Robert and I enjoy a cold one.
