Hiking the Piedra Lumbre area of La Leña. A cold, dry day with a storm moving in.
Lots of petrified wood. Not the brilliant agates we see so often but a frail, glittering mudstone that preserves knotholes and wormholes, almost the worm itself.
Fossil tree trunks dissolve into perfect wood chips: the desert floor is littered as though a stone woodcutter had passed, chopping stone trees for a stone fire.
