Landsat images of snow cover in Yellowstone during May-June 2025

Landsat 8 and 9 images of southwest Yellowstone National Park from 9-May (left), 25-May (center), and 18-June (right), 2025. The red labels are for the Madison (MP) and Pitchstone Plateaus (PP). The Yellow labels are for Shoshone (SL), Lewis (LL), Heart Lake, and Yellowstone (YL) Lakes. The Blue labels are for Lower (LGB) and Upper (UGB) Geyser Basins. The image from 9-May shows that the lakes were mostly frozen and show large amounts of snow on the Madison and Pitchstone Plateaus and their surroundings. By 25-May the lakes were mostly thawed and snow was melting in many areas other than on the plateaus. By 18-June much of the snow cover in the park had melted, except for on the Pitchstone Plateau and a few other high-elevation areas.
