More fossils...?

It was a beautiful day for a hike, but I didn't go on one. At least I figured out how the ball of my left foot keeps getting bruised. The sole of my left shoe is just about worn through. It doesn't provide any protection from rocks.

Anyway, I drove down Apache Trail, almost to where it turns to dirt. I stopped there and wandered around an area I've visited several times. I had never noticed all the stuff that looks like fossils there, though. It kind of looks like tree bark, but there's too much of it to be that. Maybe it's fossilized algal mats. I need to dig out my Arizona geology book and see if I can find out how old the rock is out there, and if it's even sedimentary.
