September 22, 2017 update
The road to Climber's Bivouac is OPEN. The summer climbing route (Monitor Ridge) out of Climber's Bivouac is the preferred climbing route for summer. A Northwest Forest Pass is required to park at Climber's Bivouac and can be purchased online, at local vendors or Forest Service office, or with cash/check at the parking lot (daily permit only, no annual available at parking lot). Dispersed camping is available around the parking lot and along the gravel road leading up to the Bivouac. There are pit toilets available, but no running water or trash service. Please plan accordingly.
Winter is right around the corner, and on the mountain it has already arrived! Patches of snow exist right from the parking lot, and on the lava flow leading up to the boulder fields there is 1-2 feet of snow, depending on exposure. Snow can obscure rocks and holes, so be aware of post-holing danger, especially among the boulders. Drifts can move piles of snow that range in depth from 4" to 4 feet. Upcoming forecast for clear skies and sun this weekend will alter the snow conditions dramatically, though rocks will continue to be slick.
Please check the forecast as weather conditions as mountain conditions can change rapidly.
