Field Work 1998 Base Camp Meteorite Hunt New Finds Map


MY WEB PAGES FOR LUCERNE DRY LAKE AND THE
LUCERNE VALLEY METEORITES

- - - REVISITING LUCERNE DRY LAKE 30 YEARS LATER - - -

The original purpose of this web page was to determine, if after 30 years, whether it can be resolved that the meteorites at Lucerne Dry Lake are members of a single strewnfield, or are multiple, overlapping falls. Subsequent analysis has shown that of the 17 known chondritic stones, 9 (nine) of them are uniquely different. What was formerly considered to be 17 members of a solitary fall event, is now known to be groups of stones from at least 9 separate falls, and are now known, collectively, as the "Lucerne Valley Meteorites".

Field work between September and November 1998 has resulted in 3 new finds by this writer. These finds have been donated to the Griffith Observatory and join the 5 other specimens that are on display. Sections have been taken from these specimens and have been characterized and paired at UCLA by Alan Rubin. Since then, samples have been taken from the other "LV" finds (16 of the 17), and these have been characterized and paired by Alan Rubin, as well. Through the generosity of all the finders and holders of "Lucerne Valley Meteorites", it has been determined that "no fewer than nine (9) separate falls" have occurred at Lucerne Dry Lake! This has brought about a re-evaluation of pairings based solely on proximity. Although the ratio of "# of falls to total # of finds" is the highest yet known, it still only corroborates the generally accepted "average meteorite flux density" of ~1 fragment for every sq. kilometer.
If additional "LV" finds are made, they will be posted here:

- - LATEST INFORMATION - -

My TABLE of Lucerne Valley Meteorites - with IMAGES, is the most current listing (has LV 013 reclassified and paired to LV 015 & LV 016) and is available to those whose browsers aren't setup to handle the MAPS ".pdf" files, just by "clicking"

Our ABSTRACT on the Pairing of L.V. Meteorites, has finally been published in the LPI Contribution No.997, for the "Workshop on Extraterrestrial Materials From Hot and Cold Deserts", July 6-8, 1999 Kwa-Maritane, Pilanesberg, South Africa, but the pre-review version is still viewable just by "clicking"

TABLE 4: Meteorites from Lucerne Valley, California, as published in Meteoritical Bulletin, No.83
This "Table 4" has been subsequently revised (classifications for LV 002 & LV 017) and is reflected in Meteoritical Bulletin, No.84
The most recent paper relating to the pairing of Lucerne Valley meteorites can be found in "Numerous unpaired meteorites exposed on a deflating playa lake at Lucerne Valley, California", RUBIN, A. E., 2000, Metorit. Planet. Sci.(MAPS) 35 (Suppl.), A181-A183

A Preliminary Report on the Lucerne Valley, San Berna[r]dino County, California, Aerolites (CN 1169,345) - a photocopy of the report as it appears in "Meteoritics, 1964, 2, p.177, Meteor. Bull., 1964 (29)" by RONALD N. HARTMAN and RONALD A. ORITI.

Catalogue of Meteorites - Lucerne Valley - a photocopy of the paragraph as it appears in the "Catalogue of Meteorites" (Blue-book version) in which the following phrase "Meteoritics, 1964, 2, p.177, Meteor. Bull., 1964 (29)" appears to give credit of authorship to J.D. Buddhue, but, as I've shown above, the "preliminary report" on "p. 177" is actually authored by RONALD N. HARTMAN and RONALD A. ORITI. A document search for a paper by J.D. Buddhue netted no results. The only other reference to this meteorite was published in RUSSIAN and only the names "R.N. Hartman, R.A. Oriti, and R.W. Leonard" appeared in that report.

The 13th, 14th, 15th, 16th, and 17th Lucerne Valley meteorite finds - the above article included a table of the 12 recorded finds from Lucerne Dry Lake. In the intervening years there have been no additional "reported" finds. A 3.4 gram individual stony (L5) with a smooth exterior was found in September 1998. Exactly 29 days later a 12.5 gram oriented individual stony (LL6) was found. This find has peculiar fusion crust (thick and frothy) and a particularly fresh interior. This appeared to be the first LL-group meteorite found in California, but subsequent analysis in 2000 has shown that LV 002 was actually an LL4 all along. Another month later, my third find was made. Another ~3 gram stony (L5-paired) with a smooth exterior. The reporting of my finds sparked renewed interest in searching for more LV finds by other field workers. At 2:30PM March 30, 1999, almost 36 years after finding the first Lucerne Valley Meteorite, Ron Hartman found a 12.8 gram specimen which is strikingly similar in appearance and shape to my September 1998 find. In 1999 it was brought to my attention that on May 9, 1992, Byron Groves recovered a 4.1 gram L5 S2 W3 stone from the same area of the lake where the original finds were made. This meteorite is now assigned as "LV 013", as of Met. Bull. 84, and my LV 014 & LV 016 are now paired to this stone. Should you find a meteorite at Lucerne Valley, you can contact me and I can have an "LV number" assigned to your meteorite!
