After a few days of driving we joined forces with Chris and all went on a hike in the park!

We started at a trailhead that features a collection of gigantic round boulders called concretions!

Me with some huge balls
cool flow patterns
More concretions in the cliff wall

From there we carried on up onto the top of the ridge with grass and wildflowers.

high plains!

buffalo!

Our first buffalo sighting!

From here we followed the trail to the prairie dog city. They were pretty cute!
