I know that everything that flies or walks has a use in fly tying, but I am looking for someone who has seen/made/used marmot in a fly. We were driving in to a spot in Idaho a month ago and came across one who didn't make it to the other side of the road. I jumped out and took the tail (too far from home to skin it). Looks like it would make a good winging material, but have no idea of its floatability for dries or wets.

Any pointers would be great!!
