Summer
It’s prime growing season for grasses, flowers, and babies in the prairie. During the hottest days, both elk and bison seek relief by finding shade trees or taking a dip in a pond. You’ll find these large animals to be most active between sunrise and sunset. If you are visiting during summer, you might want to visit the prairie just after sunrise and right before sunset.
Take caution when in the presence of bison during breeding season from July to September. Bulls can be especially aggressive at this time.
