A view of Fire Control Road with the Mogollon Rim in the distance.
As I walked along the trail I was finding some small, broken pieces of coral in the dirt. There are also many white concretions that occasionally had hollow, geodized areas within. The concretion exteriors resembled cauliflower and appear to be composed entirely of Quartz.
I was not finding any larger pieces by walking along the trail so I decided to hike uphill and see if I could find the source of the float.
It wasn't long before I found exposures of limestone poking up from the pine straw.
There were also many more pieces of the silicified coral lying about as well as some embedded in loose rock and large boulders.
Fossils other than coral were not very common but I did find some areas with brachiopods weathering out of the rock. Overall they were not as well preserved, I think due to their thin shell which fell apart easily during the weathering process.
As I was travelling I had to limit myself on how many fossils and matrix pieces I could bring back. There was so much material at the site I visited that I could easily have filled several suitcases. I'll detail some of the fossils I found in the next few blog posts.
