Not a Southern Rockies story, but I continue to be fascinated by the way that DNA analysis offers unimaged glimpses of the distant past:

Using isotopic analysis of the tusk of a male mastodon discovered on a peat farm in Fort Wayne, Indiana, researchers were able to track changes in landscape use between his teenage and adult years. During the mastodon’s early adolescence, he stuck to an area that included central Indiana and southwestern Ohio. After being kicked out of his maternal herd, his home range began to increase.

But then, things did not go so well for him. Read the whole thing.
