BLM manages more than 52,00 acres of public land in the Big Jacks Creek Wilderness. The Owyhee Canyonlands is a huge and remote area of eastern Oregon, southwestern Idaho and northern Nevada. Hidden within this vast high desert plateau are deep canyons carved by the Owyhee, Bruneau and Jarbidge Rivers. The rivers of the Owyhee and Bruneau-Jarbidge systems offer something for nearly every level of boating experience. The Owyhee and Bruneau-Jarbidge river systems provide visitors with unsurpassed solitude in canyons of unique beauty and form. From placid pools to turbulent whitewater; from vertical cliffs to steep grassy slopes; and from wildlife, such as California bighorn sheep to wildflowers, including the Bruneau River flox, these rivers and their canyons present visitors with challenging and extraordinary experiences.
