Course Preparation & Physical Fitness

Course Description

Travel by foot into the Central Oregon Cascade range, where students will have the opportunity to climb 10,000-foot glaciated volcanoes for a bird's-eye view of the spectacular surrounding terrain. Mountaineering courses move through high mountain terrain and focus on preparation for an attempt to summit a peak that may require the use of ropes, technical equipment and possibly rock climbing. During the mountaineering section, students will learn backpacking skills such as on and off-trail travel, map and compass navigation, cooking and campsite selection. You will also learn basic mountaineering skills like route finding and various terrain travel, including rock climbing skills. In September, snow and glacier travel is still possible, but less common than with the earlier season courses. Students will have the opportunity to attempt a major peak ascent, dependent on weather conditions and group dynamics.

Course Area

Central Cascades, OR – In Central Oregon, volcanoes dot the spine of the Cascade Mountains, rising up to over 10,000 feet above the forests, lakes, and rivers. These glaciated peaks run north and south and create perfect mountaineering objectives for you and your team. This range is home to the Three Sisters (North, Middle, and South Sisters), Broken Top, Mt. Washington, Three Fingered Jack and Mt. Jefferson. Four 10,000+ foot glaciated volcanoes are present in this course area, with a total of eight major volcanoes. The west side of the range is lush while the east side is drier. Central Oregon is a high desert that experiences extremes in weather conditions at varying times throughout the summer. There is potential for you to be traveling in rain, snow, or sun for the duration of your time in the mountains. Some of the peak ascents will necessitate glacier and roped-team travel.
