I made this bow off of the description and details of the Anasazi bow in the Encyclopedia of Native American Bows Arrows and Quivers Vol. 2 on page 220. The Wood is Gambel Oak, which I believe the original would have been made of. I'm sure the weight wouldn't match up but there were no detailed descriptions of the width and thickness so I decided on something heavy. 57# @ 20". The original was 44" long mine is 41" long. String is a little off center, has nothing to do with the original just the wood used.
