What makes Mt. Rainier notable?
Most glaciated peak in the Lower 48 — a serious glacier climb, not a walk-up.
Mount Rainier is the most glaciated peak in the contiguous United States. Standard routes (DC, Emmons) are glacier climbs with crevasse hazard, party travel, and overnight high camps. Stage from Ashford / Paradise, carry a climbing pass, and treat weather and seracs as trip-ending risks—not scenery.
