The Montana Bureau of Mines and Geology has produced a new geologic map of the state. I own a very worn-out copy of the previous edition, which was published in 1955. The geology of the state hasn’t changed since then, but our understanding of the state’s geology has grown considerably in a half century. The previous edition showed 76 different geological units; the new one shows 324.
With dimensions of four feet by seven feet, I’m not going to have a copy shipped to Romania, but next time I’m in Montana, I’ll want to buy this work of geologic art.
