Two climbers reported missing this week on California's towering Mount Whitney have been found dead, officials said Thursday. A friend who had been with the climbers called authorities Tuesday night after they failed to arrive as planned at their campsite, the Inyo County Sheriff's Office said in a statement. The friend said the pair had planned to ski or snowboard from the “notch,” a flat area where climbers often stop to rest, down to their camp at Upper Boy Scout Lake.
