  • A wide aerial view of Tracy Arm in Southeast Alaska shows the scar from the Aug. 10, 2025, landslide descending from a steep mountainside into the fjord near a glacier terminus. Gray rock and debris cut through the center of the mountain, reaching the water below, where floating ice and sediment spread across the fjord. The glacier terminus is visible at lower right, with snow-covered peaks rising above the surrounding mountains. Along the far side of the fjord, a pale trimline marks where the tsunami stripped vegetation from the slopes. The photograph was taken from across the fjord during a U.S. Geological Survey flight on Aug. 13, 2025.
