Hood River-based mountain guide Scott Woolums has spent the past several weeks moving up and down Mt. Everest as he and his team of three acclimatize to the altitude and prepare for the ultimate prize: reaching the summit of the world’s highest mountain.

Woolums, who owns Hood River’s Adventures International, an adventure travel company that specializes in mountain climbs and treks around the world, is accompanied by fellow Hood River mountain guide John Rust, who is leading three clients of his own in an attempt to reach the summit of Lhotse, the fourth highest mountain in the world and closest peak to Everest.
