A cluster of large boulders partially buried in snow, varying in size and shape. Surfaces alternate between exposed rugged stone and thick snowy blankets, with small icicles dangling from ledges. Snowdrifts fill the gaps between rocks, creating natural crevices and shadows. Frost coats the boulders with crystalline patterns, catching cold light softly. The cluster suggests natural windbreaks or animal shelters. Mesh should prioritize rough stone details, layered snow volumes, and delicate ice textures.
