This is terrible news. I worked with Daryn at Black Diamond and got to know him quite well. Just about a month or so ago, a group of us, including Daryn were up in Ferguson replacing old bolts and cleaning up some old messes. It was Daryn who instigated the project. We was a true climber at heart, and was concerned with access issues and in making the climbing environment a clean and beautiful place to be. He had a great and positive energy, and was friendly to everyone.
I will miss Daryn, this is so terribly shocking.
