When we were recently driving on I-70 west from Denver we took exit 254 Genesee Park to see bison! Exit 254 specifically says Buffalo Herd Overlook and the bison are right off the exit. As you can see from the pictures they were just relaxing. It was a warm day so I think that relaxing was the only option. We saw baby buffalo (calves). It was a great place to see wildlife. Next time you are driving on I-70 be sure to stop and see the bison. I found a couple of great websites that elaborate on Buffalo Herd Overlook off of I-70.
Are the words buffalo and bison interchangeable? The exit said Buffalo Herd Overlook but I have referred to buffalo as bison after seeing them in the Grand Teton National Park. What are your thoughts?
