Left Hand Creek        40°7.64’N, 105°17.62’W

Boulder County, Colorado, United States

Found: Aug 2000

Classification: Iron meteorite (IAB complex)

History: In August, 2000, a single weathered meteorite was found in colluvium on the eastern flank of the Dakota hogback near Left Hand Creek, Boulder County, Colorado. A person digging a posthole hit a large rock; it was decided not to move the hole but to remove the rock, a rusty 8.671 kg iron meteorite.

Geochemistry: (J.T. Wasson, UCLA) Analytical Data: structure = Og, bandwidth = ~2 mm, Co = 4.66 mg/g, Ni = 69.6 mg/g, Ga = 87.3 μg/g, Ge = 340 μg/g, As = 14.3 μg/g, Ir = 1.89  μg/g, and Au = 1.648 μg/g. Despite compositional similarities, this seems not to be transported mass from the Canyon Diablo strewn field. It shows resolvable differences in Ir (1.9 μg/g, lower than the lowest CD mean of 2.1 μg/g), As (14.3 μg/g, higher than the highest CD mean of 13.5 μg/g with the exception of Canyon Diablo (1949), ~16 μg/g) as well as slightly high Ga and Au.
