And in another direction.........
..........lie the Rockies of CO, WY, and MT.
Southwest and west-central MT are rich in out-of-the way ghost towns and less-visited historical sights. The towns of Bannack, Granite, and Garnet are but a small sampling. While in the vicinity one can visit Philipsburg, Butte, and Anaconda. It's around 1,200 miles from Des Moines to Butte.
Central CO is home to Leadville and Central City and innumerable ghost towns and old mining camps.
Central and NW WY are rich in mining towns and cow towns and railroad towns.
Both CO and WY are some what closer to home than NM and MT are, too.
