Speaking of stones, sometimes when I’m looking at pix from a flight something new will come to light. Like these folds in sandstone. I’m trying to figure out what would create something like this.
1633 Stone Skin
Grooves could be cut by wheels, as in the prior post about a sandstone outcrop. But what would account for a raised area with a groove down the middle, as at the top-right? At the bottom of this same large outcrop is another area with grooves.
1633 Groovy
So many places where a raised “fold” has a groove cut at the top. A raised area would seem to get more so as runoff was directed to the adjoining lower area. What could erode a channel right along the raised area?
From the air I didn’t notice any of this. Just a rock outcrop that somehow moved me to snap a pic.
1633 Glance
Maybe this distant glance at the outcrop was interesting because of the unusual texture created by the sunset-angled light on those grooves.
