The sun slips behind a layer of cloud and the summit’s silhouette sharpens against a cold, thinning sky. At nearly 14,000 feet, the wind reworks the air and the vans hum as they pull into a rim where observatories perch like instruments turned toward infinity. Guides hand out heavy-duty parkas, the group leans into hot chocolate, and the first bright stars push through.
