Pat gets a well-tread no-prize for bringing us news of efforts to preserve the Robledo Mountains fossilized track site. Containing the fossilized trackways of perhaps thousands of different paleozoic creatures, the site is only partially under the aegis of the feds, and so is vulnerable to potentially destructive development.

In many ways I think these footprint sites are more compelling than even the fossilized creatures themselves. In the latter case, all you're looking at are remains of dead things, while in the former you're looking at evidence of living things. Subtle, but important.
