They were at the far south end. Most sightings prior to this have been to the north end. I have also heard of sightings near Thermopolis and several around Arapaho Ranch areas.
They are also moving down the Wind Rivers. They used to end at Dubois, but the elk pushing into Lander last winter and other sightings up high tell me there is a significant population moving down the Wind Rivers. Rumors are of a sow up from Lander near Louis Lake.
