 Aerial view of the Schweizerland Alps in East Greenland, likely near the Sermilik Fjord region. The jagged, snow-covered peaks visible in the foreground are part of the Schweizerland mountain range (also known as the Schweizerland Alps). This is one of the highest and most alpine regions in Greenland, located just west of the town of Tasiilaq. The image shows deep valleys filled with snow and ice, with massive glaciers flowing down from the high peaks towards the fjords. The interplay of sharp ridges (are^tes) and ice-filled basins (cirques) creates a classic, high-alpine landscape that rivals the European Alps in ruggedness but on a much wilder scale. The large body of water visible in the background (center-right) is likely Sermilik Fjord, a major fjord known for being choked with icebergs calved from the Helheim and other glaciers. The water reflects the sunlight, creating a bright contrast against the darker mountains. View from a window of an airplane from Helsinki to Dallas, Greenland, October 17, 2025

 Deeper inland over the East Greenland coast, likely near the major glacial systems feeding into the Sermilik Fjord complex. The massive, heavily crevassed glacier visible in the lower center (flowing from left to right) is characteristic of the major outlet glaciers in this region, such as Helheim Glacier or Midgard Glacier. These are some of the largest and fastest-flowing glaciers in Greenland, draining huge volumes of ice from the interior ice sheet into the fjords.:200b The intensely wrinkled texture of the glacier surface is caused by deep crevasses (cracks) that form as the ice flows over uneven bedrock and bends around mountains. The chaotic, shattered appearance indicates rapid movement and significant stress within the ice. The dark, jagged peaks rising above the ice are part of the coastal mountain ranges (likely the Schweizerland Alps mentioned previously). In this view, you can see how the ice sheet wraps around and flows between these mountains, essentially burying the valleys in ice. In the bottom right corner, a turquoise-colored lake is visible. This is a proglacial lake, formed by meltwater trapped between the glacier and the mountains. The distinctive color comes from "glacial flour" (fine rock particles) suspended in the water. This transition from the rugged coastal peaks (in the previous image) to the massive, flowing rivers of ice marks the boundary between the coastal mountains and the vast Greenland Ice Sheet proper. It is the dynamic edge where the ice sheet discharges into the ocean, a critical zone for understanding global sea-level rise.
