News, Giant sinkhole caused by abandoned, century-old railroad tunnel
A giant sinkhole that caused part of a highway near the top of a Colorado mountain pass to be shut down earlier this week was caused by thawing soil in an abandoned, century-old railroad tunnel, engineers there said:
The Colorado Department of Transportation was forced to close part of U.S. 24 between Red Cliff and Leadville after the 100-foot-deep, 20-foot-wide sinkhole was discovered near the top of Tennessee Pass.

I'm surprised there was frozen soil to thaw, after this winter, even with Leadville's elevation. I wonder if it's happening in other mining areas that were so warm this year?

An article I saw said there might also be an engine down there. It was an old D&RGW line abandoned in the 40s-50s
