Tracks in the Navajo

I camped for a couple of nights at the top of Hog Canyon Road outside Kanab, Utah, to do some geological prospecting.

Specifically, I was looking for protosuchus burrows. (This animal was an ancient version of crocodile.) I found some anomalous structures in the sandstone that might be burrows, but nothing with the kind of definition I was hoping for.

However, I noticed the sand around my camp was covered with tracks made by bugs and lizards.

Then up on the outcrop where I was prospecting, I found this rock with tracks reminiscent of the tracks in the sand.

Not exactly dinosaur tracks, but still pretty cool.

These tracks in the Navajo Sandstone tell us that when these sand dunes were created, there were living animals present running around on them. The animals in this ancient neighborhood ranged in size from worms to the size of horses judging from the tracks they left. (I mention horses only for size comparison. There are no modern mammal tracks in the Navajo.)
