As we were driving to our campground, we grew a little worried to see smoke fill the sky nearby. But, we suspected it was a prescribed burn, where the park service intentionally sets fire to an area. The winds were blowing away from the campsite and the road served as a firebreak. We saw helicopters go by as they monitored the fire. The purpose is to keep the vegetation from growing up too much by mimicking the natural occurrence of fire for the health of the ecosystem.
