"Montana" has always been disappearing, ask any of our friends on the reservations. It has never been a static state, it is constantly in flux since white people first moved here for beaver pelts, gold, cattle, sheep, copper, wheat, skiing, breweries, fly fishing, amenity ranches, creationist museums, trophy hunts, data centers, etc. At the top of the stairs on the second floor of the State Capitol are statues of the leader of a vigilante lynch mob, Wilbur Sanders, next to a statue of one of the most vocal pacifists of the 20th century, Janette Rankin; two people who could not be more different. Which one is more "Montana"? Neither and both. Montana has constantly and always been disappearing and reappearing.
The entire theme of A.B. Guthrie Jr.'s The Big Sky is "man destroys the thing he loves." We've all loved Montana to death, in our own way.
