8/1/21 - Today we explored the northern unit of the Theodore Roosevelt NP.  About 50 miles separates the southern part of the national park where we are staying.

This part of the NP is similar in many ways, but has its own unique features. The black layer of earth below is actually volcanic material deposited from hundreds of eruptions, 50 to 55 million years ago.

We did take a nice  2.5 mile hike on the Achenback Trial that led out to Sperati Point.

River Bend Trail to a CCC constructed pavilion right on the edge of the canyon. Great views!

Cannon Ball Concretions (round boulders protruding from the eroded cliff).

Lots of Bison in the park.

First Longhorn steer we have seen. This guy was was about two football fields away. Super zoom on the camera.

Sunset over canyon

Right at sunset we saw a big group of Bison by our trailhead. A little worried that we might be stuck waiting for them to move on.

Last sighting for the day was a bull Elk standing about 100 yards from the park road.
