LAST EDITED ON May-15-10 AT 11:34AM (MST)[p]I've seen rutting activity in the later part of August and it just continues to build until it peaks in late Sept. I have been fortunate enough to be in the prairie many times during the heat of the rut and its sure fun to watch and listen as the pronghorn assure next year's fawn crop. I hope to be somewhere in pronghorn country this fall with my camera taking a few photos.
