This early Landsat 1 image, acquired on July 31, 1972, captures the Kennicott, Nabesna, and Barnard Glaciers in southeastern Alaska—just a week after the satellite’s launch. Using bands 6, 5, and 4, the image reveals glacial ice, rugged mountain terrain, and braided rivers within the Wrangell–St. Elias region.

Within days of the launch, Landsat 1 acquired an image of an astounding 81,000-acre (327.8 square kilometers) fire burning in isolated, central Alaska. For the first time ever, scientists and resource management officials were able to see the full extent of damage from a fire in a single image while it was still burning.
