Some Anasazi bows were scrub(gambel) oak. I live in Utah too and made a couple to test the Anasazi design. Both were from snakey trunks, but they split strait with no twist. They were light(38 and 40#). Round cross section. D bow design. 49" long and drew 24-25" no problem. One lasted years, the other got too dry in storage and let go at a knot. It will make a good bow. I've been meaning to cut more scrub. We have plenty of great bow woods here.
