750ft dunes against the Sangre de Cristos, then the vertigo-inducing rim of the Black Canyon. Expect cold, dry, high-altitude winter conditions: Great Sand Dunes highs around 40°F with overnight lows near 15–17°F, occasional light snow, windy afternoons — the dunes and Medano Creek bed will be frozen/dry. At Black Canyon (elevation ~8,000ft), South Rim Road is closed beyond Gunnison Point and groomed for cross-country skiing/snowshoeing rather than open to cars — budget extra time and traction devices for icy overlook trails.
