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
A unique feature of Leavenworth climbing, the Thunderdome/Mad Max boulder is home to "wildly steep" granite. Slopers and steep compression are the way here. There are a few other lines nearby.
Getting There
This boulder is nestled below the steep hill you see when you are atop JY. Follow an obvious trail between Nosebleed and Yosemite Highball for roughly 10 meters. You'll come to a short, slightly overhanging boulder with a rail in the middle of its face and bow-shaped right arete (the White Arete). Hike over some rocks behind and right of this boulder. To your left you'll see a small rock platform with a short slab. Throw your gear up onto the platform and climb up to it (it's V-everybody). Down and to your right is Mad Max and Thunderdome. There are a 2 other ways to get here, but this is the easiest one.
