Access Issue: Seasonal Raptor Closures Details

Each year, the USFS monitors for raptor nesting.

A pair of golden eagles regularly nest on Bridge Creek Wall. When in effect, starting January 1, PLEASE DO NOT CLIMB or travel within 1/2 mile of Bridge Creek Wall. As a reference, the climb Condorphamine Addiction is just outside of this 1/2 mile buffer, and is OK to climb still. The closure extends through August 15, but there is active monitoring to determine if the seasonal closure can be lifted earlier.

In 2014, there was an active pair of peregrine falcons at Snow Creek Wall, but no official closure was put in effect due to the location of the falcons. The site will be continually monitored with changes or removal of closures updated as necessary.

Description

Clamshell Cave hosts a variety of moderate climbs, including some enjoyable moderate cracks. Most of the lines are either trad lines or require trad gear. It is easily possible to toprope most of the lines by scrambling around the right side of the crag. Most routes end at bolted anchors. The hangers on the anchors seem to come and go, a definite nuisance since options for gear at the top of the crag aren't great. Be prepared to use the anchor on a neighboring route.

Getting There

Park 5.4 miles up Icicle creek canyon and look for a trail on the north side of the road (just past the wood sign on the right, look for a fist-shaped boulder). A well-traveled and sometimes braided trail reaches the base of the crag in 10-15 minutes. Note: stay left at the fork 5 minutes in (should cross a creek 30 yards after), or you'll end up at Central Park (ropes)/Mitchell Plateau (bouldering).
