AKA big tooth, AKA canyon maple. It's a western version of sugar maple, adapted & evolved to withstand intense drought & high elevation, plus impervious to evergreen acids. It's incredibly slow growing compared to the hard maple we most commonly know, so 20gpi & higher is quite common. The issue with it is finding trees large enough and straight enough to harvest lumber, but they do exist. Even trickier yet is finding a source for it, as it's not a commercially viable species & isn't cut for lumber. Only those in the know, whom have access, the machinery to harvest, mill, and dry, are the people who have it. Believe me when I say it is not easy, cheap, or even monetarily feasible to acquire unless you are able to clear significant profit. The plus side to it is that it often times is quite figured & burled, but again, not so easy to get to. Where it grows is generally extremely difficult & dangerous terrain.
