Tree trunk mold

Tree trunk mold
In the Lava Cast Forest, Deschutes National Forest, outside Bend, Oregon. A young (ca. 8000 years BP) basalt flow from Newberry Volcano engulfed a forest, and many of the trunks left hollow casts. The lava would chill and harden around the tree, and then the wood would burn out to leave a mold, as here.

It's one of those "geologic oddball" places that's worth a visit if you're in the area--
