Hey! Im new to this site, and could REALLY use alittle "insight, and help" identifying, and figuring out the "what's, & when's" of this artifact. I have been(unsuccesfully), looking for ANY/ALL INFO, on this piece since I found it nearly 20 years ago! (Heres the "set up").- I found this item when I was around 9 years old, on a vaction to a dude ranch just outside Yellowstone National Park. It was located just outside the Eastern entrance to the park, and West of Cody, Wy. in the tiny village of Wappitti Wy.(the name of the dude ranch itself is "crossed sabres", & is the oldest continuous dude ranch in the country). I found the artifact 3/4's of the way burried facing straight up, and down on a mud path infront of my cabin, after a 2 day "deluge" of a rain storm. I was VERY YOUNG, and had no idea how lucky I really was. After showing it to the staff, and my parents I was told to hold onto it, and bring er' home.-so I did, and here I am nearly 25 years later, and still in awe of my lucky, mysterious find! The ONLY thing I really do know of the piece, is that it is most likely obsidian, and TOO BIG to be an arrowhead. Its roughly 4"inches long, 2"inches wide at its base, 2"1/2"inches at its widest point, and nearly 1/2" at its thickest point. It does appear that 1 side is sharper, and more "refined" than the other. The sharp side is opposite the side with the more deffined notch. If ANYONE has ANY IDEA, or info pretaining this artifact, I greatly appreciate any reply! And would NO doubt be indebted to whomever could help! Thanx again, & if you would like more pictures, have ANY more questions or comments, please feel free to comment, or contact me elsewhere at ericbrets@gmail.com Thanks once again for takin' a look at my (over-done) looong post! :-)
