63. Sorry if this is a little late |

It's sandstone that's been weathered slightly differently, but probably in situ. The "wood grain" you see are laminae, they match perfectly with the laminae in all the weathered sandstone nearby. It may be a chunk that's been subject to a lot of ventifaction, or has simply had the surrounding dust blown away.
