Columbia Boulder

From Wikipedia, the free encyclopedia

Columbia Boulder is a 30-foot-tall (9.1 m) boulder located in Camp 4 at Yosemite National Park. It is the largest boulder in Camp 4 and easily seen from the campground. According to Mike Borghoff, there are no easy bouldering problems on Columbia Boulder.[1] There are several bouldering problems on Columbia including the iconic Midnight Lightning.[2] Other famous routes on the boulder include: Robbins Eliminate, named after Royal Robbins; Bates Problem, named after Barry Bates; and Ament ArĂȘte, named after Pat Ament.[2] In attempts to improve relations between climbers and park rangers, discussions over free coffee usually take place once a week from spring to autumn beside Columbia Boulder.[3]
