Bison grazing in Badlands National Park. This is an experiment with single-line drawing. The whole sketch was made without lifting the pen from the page. I sketched from a photo after doing some plein-air sketches yesterday in a wind that was strong enough that it was hard to keep my sketchpad from blowing away.

The bison in South Dakota number in the thousands, though they used to number in the millions. The herds that roam Badlands National Park and Custer State Park are the descendants of a small number of bison that were saved by a small number of people.

I often wonder what the ecology of our region would be like if the bison still existed in numbers like they once had.
