A wooden 2 x 4 that was used to stack with bongs in the wide cracks of Excalibur, El Capitan. Excalibur was done by Charlie Porter and Hugh Burton in 1975. The 2 x 4 was found at the base by Grant Hiskes and showed evidence of having split on the climb. Oddly enough, several years later Ken Yager found the matching piece to it.
