Someone correct me if I am wrong, but the directions to Tibble Fork damn is from the entrance of the American Fork Canyon (not from the alpine loop) you just go through the pay booth and it is the first LEFT that actually is a road. It is paved, and you just stay on there until you get to the huge parking lot and the damn.
Still do not know if I am going to get to go. Wife will not tell me. Hope I see yall up there.
