Hansen Hat and RCS pins
Felt hat that belonged to 1940's climber Robin Hansen. The hat has the first 2 metal pins given to RCS (Rock Climbing Section) members of the Sierra Club. The first pin on the left was designed by Torcum Bedayn. A second more durable pin was designed by Ronald Hahn after it was discovered that Torcum's baked enamel pin chipped while climbing. Robin Hansen is best known for being the one that suceeded in throwing the rope over the Lost Arrow Tip during the first ascent in 1946. This "rope trick" as Salathe called it, spurred Salathe to climb to the Lost Arrow Tip starting from the bottom of the wall with Ax Nelson who was on the 1946 ascent. They called their route, the Lost Arrow Chimney, and completed it in 4 1/2 days in 1947 making it Yosemite's first big wall.
