On Saturday, Allen School Ph.D. student Galen Weld, his twin brother Adam, his father (and Allen School professor) Dan, and his mom Margaret Rosenfeld reached the 8,528-foot summit of Buck Mountain in the Glacier Peak Wilderness. With that achievement, Galen became the youngest person to summit each of the 100 highest peaks in Washington, and Dan and Galen became the first father-son team to achieve this milestone. (Dan completed his summit of Washington’s “Top 100” in 2016.)
