North Cascades: Luedtke and Team Ready for South Twin Sister

August 26, 2025

Posted by: Ben Luedtke, Bailey Servais, Calvin Jiricko

Categories: Expedition Dispatches North Cascades

Elevation: South Twin Sister

Today, we sauntered into the wilderness of Washington for our first objective: South Twin Sister.
“What are we doing?” you might ask. “Where the heck is that?” you may wonder. Spoiler alert: it’s a hidden gem of a climb just south of Mt. Baker.

After crossing a downed tree over a raging creek and bushwhacking through a sea of berries, we arrived at camp nestled in a field of boulders. The question kept coming: “Have y’all done this climb before?” Sure have.

We spent the afternoon refreshing our skills in preparation for what’s to come. Hiding from the sun and heat, we’re hoping to get some sleep tonight.

Tomorrow, we climb.
