A mountain rises within the Fairweather Range, its ice-covered slopes and rugged ridgelines looming above Margerie Glacier. The glacier fills the foreground, its fractured surface revealing crevasses and subtle shifts in color that trace the slow movement of ice. A dark, winding band of rocky debris cuts across the glacier—a medial moraine formed where merging ice streams carry accumulated sediment downslope. This ribbon of stone records years of erosion and transport, linking the mountain’s broken rock to the glacier below and highlighting the dynamic processes that continue to shape Glacier Bay’s dramatic landscape.
