I found a meteorite fragment in Montana whilst looking for a missing cow back in 1998. It was on a yellow sandy hill, close to the top, at the side of a shallow valley, and stuck out like a sore thumb as it was black and all the other rocks were yellowish/grey-white limestone. It was just lying on the surface not buried and was kidney shaped, around 9-10" long and 4" wide at the widest end, and around 1 3/4" deep at the thickest part. It was very heavy for it's size, I reckon over 3 1/2lb and had flecks of rust in it and had obviously been subjected to great heat at sometime as it was blackened and had small holes over it's entire surface, which was otherwise fairly smooth.
It is currently in a private museum in the small town of Fromberg MT amongst many other interesting locally found items such as Native American artifacts, arrowheads, axes etc. fossils and various other rocks and minerals. Yellowstone Park is around 170 miles south west of there. I wish I had photographed it but never did.
