Mid-March 2024 at the Donner Summit rest area (east-bound). I suppose once the building was dug out, ice formed in the alcove as heat warmed the snow’s bottom (ceiling in this case). Pretty neat. 📷 #MBApr An alcove filled with a large accumulation of snow and ice, with a metallic overhang above and stone pillars on the sides. A trash receptacle sits partially visible in the foreground to the left.
