Tracking Hells Canyon Bighorns

Idaho Fish and Game biologist Frances Cassirer takes a blood sample from a bighorn sheep ram near Heller Bar, south of Asotin, Wash. On Monday and Tuesday wildlife officials from Idaho, Oregon and Washington and a helicopter crew from Leading Edge Aviation captured several bighorns and fitted them with radio collars that track their movements as part of the ongoing effort to recover wild sheep in Hells Canyon.
