[meteorite-list] Almahata Sitta Meteorite
Dear list members, We are happy to let you know that we can offer few small specimens of Almahata Sitta MS-CH for sale. MS-CH is a Chondrite classified as unique with a total mass of only 5.68g. Most of the material is in the hands of science. A scientific paper of 11 pages by Prof Dr Addi Bischoff and his team of scientists has been exclusively dedicated to MS-CH in the special edition of “Meteoritics Planetary Science” which was published in January 2011. The whole edition comprises different research papers on the Almahata Sitta fall from Asteroid 2008 TC3. At present, a fragment of MS-CH, various other Almhata Sitta specimens, as well as different lunar meteorites are being auctioned on Ebay (haberer-meteorite_de). We would like to point out that the examination results published in the above mentioned special edition of “Meteoritics Planetary Science” are mainly based on samples from material which was obtained from us. Some of these pieces are being offered for sale on our website.

[meteorite-list] Ad - New Trinitite, Olivine Diogenite, Obscure NWA's, Unclassifieds, Zunhua Micros, and Peas. :)
Hi Friends and Collectors, Some new arrivals today to announce - I bought a large batch of trinitite which consists of about a thousand individual pieces (I have not counted them yet). While sorting through them, I noticed some red pieces - a couple of larger ones and a few smaller ones. I also scored a few large pieces that have a flat profile, so they show lots of surface area for the weight. These are about the size of a half-dollar - which is about as big as most trinitite on the market gets before it breaks. I also received some very nice olivine diogenite fragments that are large and crystalline in appearance. These are NWA 6149 and it is paired with NWA 1877. Next, I finished sorting through the large batch of tektites that came in, and I pulled out some nice examples of tear-drop shapes. Lastly, I did a trade with a fellow collector and I received several obscure and rarely-seen NWA meteorites that I offering for sale. Most of these are one-off specimens and I only have one of each in stock. I don't usually stock these and probably won't get any more once these are gone because this was a one-time deal.

[meteorite-list] Why Are Death Valley's Rocks Moving Themselves? -- not off-topic at all!
Hi Michael, IMHO, it's definitely ice-rafting. It happens on any desert playa that is hard enough, receives sufficient winter rains, and gets cold enough to freeze at night. In California, I've seen the rock furrows at Silver Dry Lake, Superior Dry Lake, Cuddeback Dry Lake and (most recently) Coyote Dry Lake. I've also seen them on some Nevada playas as well as the Alvord Desert in Oregon, and they occur in Arizona, as well. SoCal got a lot of rain this past December -- so much so that even after three weeks of dry weather in January the northern third of Coyote was under water. I've never seen this in the decade I've been going there, and sure enough I saw rock trails there for the first time last month. Bob Verish, Nick Gessler and I coauthored an abstract and presentation on this subject, and in particular its implications for meteorite recovery, at the 65th Annual Meeting of the Meteoritical Society in 2002: http://adsabs.harvard.edu/full/2002M%26PSA..37Q..51G Cheers, Rob -Original Message- From: meteorite-list-boun...@meteoritecentral.com [mailto:meteorite-list-boun...@meteoritecentral.com]On Behalf Of Michael Groetz Sent: Friday, February 18, 2011 5:24 PM To: Meteorite List Subject: [meteorite-list] OT (Sorta...)

By Philip Schewe Published February 18, 2011 | Inside Science News Service Death Valley National Park contains many mysteries, including one of nature's strangest phenomena: rocks that seem to move around all on their own. In the remote, almost totally dry lakebed called Racetrack Playa, some of the rocks move themselves across the desert floor when people aren't watching. Scientists know the rocks move because they leave narrow tracks trailing behind them, but they haven't actually seen it happen. And although one can't entirely rule out the possibility of some prank being played, at least some of the rocks appear to be moving under natural circumstances. It doesn't rain often in Racetrack Playa, and when it does the lakebed can flood. The rocks don't float exactly, but the main explanation for their movement is that moisture can make the mud on which the rocks sit more slick, making it easier for high winds to push the rocks along. Another explanation offered is that the temporary deposit of water, chilled to form extensive sheets of ice, might help to reflect and focus the winds, making it easier for the rocks to move. The winds required to move rocks in this way would seem to be at the level of 100 mph or more. That's why the rocks are sometimes referred to as sailing stones. They are rare but they have been noticed in Racetrack Playa and a few other arid places around the world subject to occasional floods Ralph Lorenz, a scientist at Johns Hopkins University, offers a new explanation. The rocks are actually lifted up by the ice, or at least made more buoyant by the ice, making it easier for the rocks to migrate. If the rocks are moving about on ice rafts, the ground below cannot offer as much resistance against their motion and the winds needed for movement wouldn't have to be as great, he argued. So why hasn't the motion been observed? Movement happens for only tens of seconds, at intervals spaced typically by several years, said Lorenz. This would demand exceptional patience as well as luck. So, the rocks are probably traveling on the coldest and windiest days that occur over a period of several years. The most likely time would be in the very early dawn. Little wonder no one is around to witness the event. Lorenz and his colleagues would like to install inexpensive time-lapse monitoring of the Playa area, using digital cameras. The lakebed is about 2.5 miles long and 1.25 miles wide. They have also performed some laboratory tests by blowing on ice-assisted rocks. These simple tests support the ice-raft hypothesis. The results appear in the January 2011 issue of the American Journal of Physics. An additional reason for studying the rocks of Racetrack Playa is that its qualities resemble those at a drying-up lake on Saturn's moon Titan. Pictures taken by the Cassini-Huygens mission reveal what look like river channels, cobblestones, and lake beds or mud flats. Only at Titan's Ontario Lacus, as one interesting site is called, the runoff consists of liquid hydrocarbons, not water. Some pictures even seem to be showing a bathtub ring left by what is probably a drying lake. One of Lorenz's colleagues, Brian K. Jackson, who works at NASA's Goddard Space Flight Center, also likes the idea that their research at Racetrack Playa has a dual purpose. It's been exciting trying to solve a mystery that has
Re: [meteorite-list] Why Are Death Valley's Rocks Moving Themselves? -- not off-topic at all!
Michael, Rob, List I encountered these rock trails on Red Dry Lake last year. Some were a hundred feet long or more! I saw two trails side by side that made a 10 degree turn at the same time, indicating to me a shift of wind and ice float direction. From article below: Movement happens for only tens of seconds, at intervals spaced typically by several years, said Lorenz I'm not sure this scenario makes sense. Why couldn't the ice float move 10's of feet or more at a time? I think the trails I saw, described above, contradict this theory.

Re: [meteorite-list] Why Are Death Valley's Rocks Moving Themselves? -- not off-topic at all!
There is no doubt whatsoever that wind plays a major part in it. I observed a large rock and a piece of galvanized sheet metal side by side about ten years ago. I recently observed the same rock and piece of metal but this time they were separated by about 50 feet. The trail of the rock went straight but the metal acting like a keel or rudder moved off in another direction. It is obvious that the metal acted like sail since its trail was much longer. You could tell the difference between true and apparent wind direction was about 12%.

Hi Rob and all! I was out at Danby this last weekend. Some rocks on the dry lake had been on the move! There were a couple of rocks I noticed with marks about 1 foot long. There were also broken bush limbs with same marks. This area was under water and very muddy for the last month or so. Although it did get below freezing a few times, I am thinking the water had a big part in the movement, along with the wind. That mud gets slicker than snot when wet (I learned that several times the hard way over the years). The tracks I noticed showed the rocks moving North or little North of the Old Woman range!!

Would you please explain what is meant by ice-rafting in laymen's terms?? Stuart McDaniel Lawndale, NC Secr., Cleve. Co.

Hi Michael, IMHO, it's definitely ice-rafting. It happens on any desert playa that is hard enough, receives sufficient winter rains, and gets cold enough to freeze at night. In California, I've seen the rock furrows at Silver Dry Lake, Superior Dry Lake, Cuddeback Dry Lake and (most recently) Coyote Dry Lake. I've also seen them on some Nevada playas as well as the Alvord Desert in Oregon, and they occur in Arizona, as well. SoCal got a lot of rain this past December -- so much so that even after three weeks of dry weather in January the northern third of Coyote was under water. I've never seen this in the decade I've been going there, and sure enough I saw rock trails there for the first time last month.

By Philip Schewe Published February 18, 2011 | Inside Science News Service Death Valley National Park contains many mysteries, including one of nature's strangest phenomena: rocks that seem to move around all on their own. In the remote, almost totally dry lakebed called Racetrack Playa, some of the rocks move themselves across the desert floor when people aren't watching. Scientists know the rocks move because they leave narrow tracks trailing behind them, but they haven't actually seen it happen. And although one can't entirely rule out the possibility of some prank being played, at least some of the rocks appear to be moving under natural circumstances. It doesn't rain often in Racetrack Playa, and when it does the lakebed can flood. The rocks don't float exactly, but the main explanation for their movement is that moisture can make the mud on which the rocks sit more slick, making it easier for high winds to push the rocks along. Another explanation offered is that the temporary deposit of water, chilled to form extensive sheets of ice, might help to reflect and focus the winds, making it easier for the rocks to move. The winds required to move rocks in this way would seem to be at the level of 100 mph or more. That's why the rocks are sometimes referred to as sailing stones. They are rare but they have been noticed in Racetrack Playa and a few other arid places around the world subject to occasional floods Ralph Lorenz, a scientist at Johns Hopkins University, offers a new explanation. The rocks are actually lifted up by the ice, or at least made more buoyant by the ice, making it easier for the rocks to migrate. If the rocks are moving about on ice rafts, the ground below cannot offer as much resistance against their motion and the winds needed for movement wouldn't have to be as great, he argued. So why hasn't the motion been observed? Movement happens for only tens of seconds, at intervals spaced typically by several years, said Lorenz. This would demand exceptional patience as well as luck. So, the rocks are probably traveling on the coldest and windiest days that occur over a period of several years. The most likely time would be in the very early dawn. Little wonder no one is around to witness the event. Lorenz and his colleagues would like to install inexpensive time-lapse monitoring of the Playa area, using digital cameras. The lakebed is about 2.5 miles long and 1.25 miles wide. They have also performed some laboratory tests by blowing on ice-assisted rocks. These simple tests support the ice-raft hypothesis. The results appear in the January 2011 issue of the American Journal of Physics. An additional reason for studying the rocks of Racetrack Playa is that its qualities resemble those at a drying-up lake on Saturn's moon Titan. Pictures taken by the Cassini-Huygens mission reveal what look like river channels, cobblestones, and lake beds or mud flats. Only at Titan's Ontario Lacus, as one interesting site is called, the runoff

ice rafting is a misleading term, it actually has nothing to do with ice. The term is used to describe what happens when the martian blood vessels inside the rock come to life and begin the process of animating the stone so it can move. ;) -- Mike Gilmer - Galactic Stone Ironworks Meteorites Website - http://www.galactic-stone.com Facebook - http://www.facebook.com/galacticstone News Feed - http://www.galactic-stone.com/rss/126516 Twitter - http://twitter.com/galacticstone Meteorite Top List - http://meteorite.gotop100.com EOM - http://www.encyclopedia-of-meteorites.com/collection.aspx?id=1564 --- On 2/19/11, Stuart McDaniel actionshoot...@carolina.rr.com wrote: Would you please explain what is meant by ice-rafting in laymen's terms??
