A backcountry skier has died in an avalanche in Siskiyou County. Search and rescue teams were on a recovery mission near Etna Summit Thursday morning. Two men from Ashland became buried in snow on Wednesday afternoon. 37-year-old Ben Koerber escaped and was able to dig 35-year-old Brook Golling out of the snow, but he could not revive him. Koerber had to ski the rest of the way down the mountain and drive into Etna in order to call for help.
