Many of Midwesterner pioneers when moving to all the western states in the late 1800’s and later by dustbowl refugees during the 1930’s depression, often brought and planted Osage trees. In most of those places, it didn’t survive, was cut down for firewood, or considered “Trashwood” and cut down. Where I grew up, the edge of the Mojave desert in Southern California (Quart Hill to be specific), we had a several dozen houses and farms that had Osage wind breaks from 1/4 mile to several miles long, much like you see in the Midwest. Dustbowl refugees planted most the Osage in this area. I have personally seen Osage trees in Idaho, Oregon, Nevada, Washington, and Utah, and every part of California except the Northwest coast. I was told there are a couple of Osage trees somewhere in Montana, on public land, (I trust and believe the person) but he wants them for himself. It is out there, but in limited quantities, most often on private land, and seldom in the form of prime bow wood.
