Just a cute little camo bison tube hanging around. You do not need to leave the top of the hill. Good luck. Its not in the park so the park's 0700-1800 hours don't apply, however, nearest parking is half a mile away when the park is closed. Coordinates are the averaged value of averaged coordinates taken on four visits over three days using a GPSMAP 64st. Every time I came back the previous reading put me in a different spot so hopefully the averaged coordinates provide a good GZ.
