Sea Creatures and Arrowheads

My habit has always been to look for collectable rocks as I walk anywhere in this world of mine.  While hiking across the top of Rountop (overlooking Thermopolis, Wyoming), an oddly colored rock caught my attention.  When I scooped up the rock, I discovered a chip of flint.

Geologically, the flint didn’t belong on top of the butte.

Before long, I and my nephew, Marshall, were poking around the area where I discovered the flint.  Within a few minutes, we found several chips of chert and flint that appeared to have been knapped from larger pieces of stone in the process of making arrowheads.

Eventually, I found the tip of an arrowhead there.

While scouring for arrowheads (from the era when Plains Indians dominated the land), I also found several ancient sea fossils now weathered free from the butte’s limestone cap.

On my hike back down from the top, I found a nearly complete arrowhead on the trail.
