High, Trailwalker. I live in Utah, too, Davis County.
The (red) water birch is one I made bow from, kind of before I actually started making "real" bows. It's probably usable for light weight bows, but it is not the greatest stuff. Pretty soft, hard to see the grain, and kind of brittle. I would definitely not leave the bark on.
Contact me through PM if you need some wood. A lot of medium grade stuff sort of falls into my hands, stuff like elm and white mullberry. I always have more than I can ruin!
