In August of 1975, a farmer found a single large stone in a wheatfield. The weathered mass seemed strange, and it was eventually recognized as a meteorite. Analysis revealed it to be an H/L4 chondrite. Although it is an ordinary chondrite, it is a rare H/L4, of which there are only 14 known to science.
