This list is only as good as the time, effort, content and civility that people put into it. Starting a new list is just a cop-out; if a bunch of drug dealers moved into your neighborhood, would you throw in the towel and move? No. You'd band together with your neighbors and take back the neighborhood. This very strategy was suggested here last year -- I forget by whom (Bernd?). Since this list is unmoderated, the best approach is to ignore the abusers and attempt to dillute the flame wars and off-topic posts by adding *content*. Some of the most interesting stories are the ones that are rarely told here -- meteorite hunting stories. Instead, these tend to be revealed slowly by word of mouth due to the need for secrecy or confidentiality/proprietary concerns. (You never saw Franconia mentioned here until the news was out by word of mouth at Tucson last year.) I was going to wait until the preprint of Meteoritical Bulletin #89 comes out, but in the spirit of taking my own advice above, I thought I'd spill the beans early. As many of you know, I've spent a fair amount of time over the last 5+ years systematically searching dry lakes primarily in California and Nevada. The very first playa I visited was Lucerne dry lake, primarily due to the wealth of information available online about the place. But before I get into my work there, let me give a little history for those less familiar with Lucerne. Over 40 years ago, our own Ron Hartman hit upon the idea of hunting dry lakes for meteorites, reasoning that your odds of success would be vastly improved thanks to the lack of vegetation, the (generally) small number of terrestrial rocks to contend with, the convenience of hunting from a moving vehicle, and the slower weathering rates of meteorites in the high desert. In July 1963, Ron found the first meteorite at Lucerne dry lake -- a small L6 chondrite -- proving that his approach could indeed produce results. A month later, Ronald Oriti found two additional meteorites at Lucerne: an LL4 and an H6. That October, Ron Hartman went on to find two more fragments paired to his original L6 find, and the following month Roderick Leonard discovered an H4 and a second chondrite that was not classified. So the first seven finds represented at least four separate falls -- probably completely unexpected at that time given the relatively small area involved (about 16 km^2, very little of which could have been covered in 1963). Five additional finds were made by five separate people over the next 5 years, each weighing less than 10 grams (including Lucerne Valley 009 by tektite expert Darryl Futrell). Lucerne Valley 013 was a long time coming -- found by Byron Groves in 1992, 24 years after Darwin Ochs found #12. Another gap of six years followed before Bob Verish came on the scene, discovering LV 014, 015 and 016 in the space of less than two months in the autumn of 1998. (The LV 014 find is credited to both Bob and his wife, Beth.) This new string of successes must have been too much for Ron Hartman, who returned in March 1999 and found LV 017 -- over 35 years after making his first find there! To recap, here's a list of those first 17 finds: 1963 ---- 001: L6, S2, W3 Fa 24.3 +/- 0.3, 15.8g, Ronald N. Hartman 002: LL4, S2, W3 Fa 27.5 +/- 0.6, 5.8g, Ronald A. Oriti 003: H6, S3, W3 Fa 18.0 +/- 0.4, 7.5g, R. Oriti 004: L6, S2, W3 Fa 24.2 +/- 0.3, 37.4g, R. Hartman (physically paired to LV 005 and paired to LV 001) 005: L6, S2, W3 Fa 24.2 +/- 0.3, 3.1g, R. Hartman (physically paired to LV 004 and paried to LV 001) 006: H4, S2, W3 Fa 18.2 +/- 0.4, 26.9g, Roderick W. Leonard (paired with LV 008-010) 007: stone, 4.8g, R. Leonard 1964 ---- 008: H4, S2, W3 Fa 18.5 +/- 0.4, 2.0g, Steve Lieberman (paired with LV 006, LV 009-010) 1965 ---- 009: H4, S2, W2 Fa 18.7 +/- 0.2, 3.0g, Darryl Futrell (paired with LV 006, 008, 010) 010: H4, S2, W3 Fa 18.2 +/- 0.4, 6.4g, Alan Crisp (paired with LV 006, 008-009) 1968 ---- 011: L6, S4, W3 Fa 24.5 +/- 0.2, 3.8g, Richard Russell 012: H6, S2, W3 Fa 19.4 +/- 0.3, 1.2g, Darwin Ochs 1992 ---- 013: L5, S2, W3 Fa 25.3 +/- 0.3, 4.1g, Byron Groves (probably paired with LV014, 016) 1998 ---- 014: L5, S2, W4 Fa 24.6 +/- 0.2, 3.4g, Beth and Robert Verish (probably paired with LV013, 016) 015: LL6, S3, W2 Fa 30.9 +/- 0.1, 12.5g, R. Verish 016: L5, S2, W3 Fa 25.2 +/- 0.2, 4.1g, R. Verish (probably paired with LV 013, 016) 1999 ---- 017: L6, S3, W4 Fa 25.5 +/- 0.6, 12.8g, R.
