Find/Fall Anniversary |
267 gram quarter slice and 242 gram oriented individual. H6
TKW 71.4 kg. Observed fall 13 June 1998, Roosevelt County, New Mexico, USA.
From the MetBul:
After detonations were heard and smoky trails seen in the sky, a shower of meteorites landed near Portales, New Mexico. 53 objects have been recovered, with a total mass of 71.4 kg. The largest pieces weighed 16.5 kg (witnessed to fall by Nelda Wallace and Fred Stafford), 17.0 kg (found by Elton Brown), and at least nine others over 1 kg. A 530 g fragment went through the roof of Gayle Newberry's barn and embedded itself in a wall, indicating a trajectory west to east. The elliptical strewn field is approximately 7.7 x 2 km, trending N60–65ºE, although recent reports may extend this somewhat.

These two specimens are the highlights of my collection.
It is classified as an H6 chondrite according to the Meteoritical Society database, but Ruzicka and others (2005) refer to it as an H7, metallic-melt breccia.
TKW: 118 kg. (including the 34 kg main mass and other new finds)
Photo 1. Photo of both specimens, a 267 gram quarter slice and a 242 gram oriented individual. The quarter slice was taken from the 75 pound (34 kg) main mass found by Robert Woolard three months after the fall. It shows the metal and stone brecciation that Portales Valley is noted for. It measures about 17 x 15.5 cm. Full slices from the main mass are highlights in museums worldwide. The oriented individual is mostly composed of stony material and was found within a week after the fall.

Hi Steve, Thought about etching it, but it's only 4 mm thick and could easily break in transit. I'd rather not chance it and keep it whole ;-) |

Great pair, Frank! Thanks for submitting them!! Have you thought about etching that large, wonderful slice? PV shows some really nice patterns, but I also understand wanting to leave it as it is :) |

Thanks Bernd, Twink, I hadn't notice the heart, but now I do. And yes John, a cosmic fender-bender. |

Wow...and an amazing aspect about PV is the chondrite portion looks like it was only in a "fender bender", and not a major collision !! |
