I visited the Tallgrass Prairie Preserve north of Pawhuska Oklahoma on the annual buffalo roundup. I decided to combine a few of the images of the bison into both a time lapse and photo montage along with a few of the key points I learned during the day.

The Tallgrass prairie preserve is owned and managed by the Nature Conservancy. More information: nature.org/wherewework/northamerica/states/oklahoma/preserves/tallgrass.html
