Bend, OR
In the high desert east of the Cascade crest, at 3,460ft MSL. Bend has transformed from a small lumber town into one of the fastest-growing recreation destinations in the western US — mountain biking, climbing, brewing, and Cascade-volcano skiing all overlap here. Single 5,200ft runway 16/34, uncontrolled. The Three Sisters and Mount Bachelor rise 20 miles west; Smith Rock State Park's rhyolite climbing walls are 25 miles north; Crater Lake is 90 miles south. Density altitude is a year-round consideration — summer DA at KBDN can hit 7,000ft. Epic Aviation runs the FBO and the on-field flight school.
The birthplace of American sport climbing, where Alan Watts pioneered the first bolted routes in the early 1980s. The park's welded tuff and basalt walls — pinkish-orange volcanic rock — rise hundreds of feet straight out of the Crooked River canyon. Routes like "To Bolt or Not to Be" (the first 5.14a in the US) made this place famous. From the air, the rock formations look like a geological riot: spires, fins, and walls of orange stone twisting in a river bend. Monkey Face — a 350-foot freestanding spire that genuinely resembles a primate skull — is the most photographed feature. Day hike or full climbing trip; either way, unforgettable.
A massive shield volcano whose caldera holds two crater lakes — Paulina Lake and East Lake — separated by Big Obsidian Flow, a 1,300-year-old lava flow of glass-black obsidian that still looks freshly poured. The volcano covers 1,200 square miles, making it one of the largest in the Cascade Range by area (though not height). Lava River Cave (a mile-long lava tube), Lava Cast Forest (trees encased in solidified lava 7,000 years ago), and a forest of cinder cones along the east flank make this one of the most geologically diverse single sites in the Pacific Northwest. Recently active — the obsidian flow is the most recent eruption in Oregon.
Three closely-spaced stratovolcanoes — North Sister (10,085 ft), Middle Sister (10,047 ft), and South Sister (10,358 ft) — running north-south along the Cascade crest west of Bend. North Sister is the oldest and most eroded, all rotted volcanic rock and exposed dikes. South Sister is the youngest and most likely to erupt next (USGS monitors active ground deformation). Between them sits Middle Sister, the symmetric postcard cone. Surrounding the Sisters is a wilderness of lava flows, pumice plains, alpine lakes, and Collier Glacier — one of the largest in the lower 48 outside of Washington and Wyoming.
The deepest lake in the United States — 1,949 feet — and the cleanest, with Secchi depth measurements regularly over 130 feet. Formed 7,700 years ago when Mount Mazama collapsed in an eruption 42 times larger than Mt. St. Helens 1980. The caldera filled with snowmelt and is fed only by precipitation; no rivers in or out. The water is cobalt blue from extreme depth and clarity. Wizard Island in the southwest corner is a cinder cone that built up after the caldera formed. From the air the contrast between the lake and the rim forest is unreal. Crater Lake National Park is Oregon's only national park. Closest field is KSXT Sexton Memorial 50 nm southwest, or KLMT Klamath Falls 35 nm south — KRDM Redmond is 90 nm north for general access.
