    A pyramid-shaped stack of rectangular white/cream-colored blocks is arranged on a wet asphalt surface. The blocks appear to be handmade soap bars, stacked in a stepped pyramid formation with approximately 3-4 rows. The setting is outdoors in winter conditions, with snow visible in the background.

    A pyramid-shaped stack of rectangular white/cream-colored blocks is arranged on a wet asphalt surface. The blocks appear to be handmade soap bars, stacked in a stepped pyramid formation with approximately 3-4 rows. The setting is outdoors in winter conditions, with snow visible in the background.
    The image shows a trailer-mounted 'LEGI Series' snow block press machine photographed inside an industrial warehouse or workshop. The machine is tan/beige colored and features annotated labels indicating the snow processing workflow: processed snow enters via a top hopper, pressure is applied in the middle chamber, and compressed snow blocks exit from the side. The equipment appears to be new or well-maintained and is designed to be towed by a vehicle via its hitch assembly.
