San Bernardino Mountains The San Bernardino mountains from 8000 feet, on fuller ridge. I get to descend 7000 feet to the desert in the next 18 miles, then go back up into those mountains. The altitude started to get to me today too, hope it gets better. A post shared by Sean Staaleson (@seans.tall.son) on May 5, 2018 at 5:20pm PDT Posted by seanstaal View all posts by seanstaal
