The Press Traverse is a relatively well-known north-south route across the Olympic Mountains, first completed by European explorers in 1890.

It took the original Press Expedition six months to blaze a trail through the heart of the Olympics.

Mount Hood is the tallest mountain in Oregon and one of the most climbed Cascade volcanoes. It stands at 11,250ft. It is a relatively easy climb/hike for the first 4,000 vertical feet, with the last approximately 1,000ft being technical snow climbing.
