I was hiking near Sedona last weekend and finally understood what 'desert varnish' actually is.

My first time seeing desert varnish was on a rock face in Capitol Reef, this dark streak that looked like someone spilled paint. I actually thought it was some kind of mineral deposit from water runoff. Learning it's a buildup from bacteria and clay over thousands of years completely blew my mind. It makes you realize how much slow, quiet work goes on in a place that seems so still.

Come on @seth_carr, it's just a dirty rock. You're giving way too much credit to some old bacteria.
