Bear Valley Refuge was established in 1978 to protect a vital night roost site for wintering bald eagles. The Refuge consists of 4,200 acres, primarily of old growth ponderosa pine, incense cedar, white and Douglas fir. These mature stands of trees have open branching patterns of large limbs which allow easy eagle access and can support many birds. Located on a northeast slope, the roost also shelters these raptors from harsh and prevailing winter winds. In recent years, as may as 300 bald eagles have used the roost in a single night. Bear Valley Refuge also serves as nesting habitat for several bald eagle pairs. Bear Valley Refuge is closed to all public entry, except for walk-in deer hunting before November 1, to reduce disturbance to the birds. From December through mid-March excellent opportunities are available from outside the Refuge to observe early morning fly-outs of large numbers of bald eagles and other raptors from their Bear Valley roost.
