Snow leopard mother guarding cub at snowy sinkhole edge

A breathtaking photorealistic wildlife documentary scene showing the same adult female snow leopard standing cautiously beside a massive circular sinkhole in deep snow while looking down toward her trapped cub. The cub is barely visible at the bottom of the dark icy pit with only its head above freezing water, creating an emotional moment between mother and baby. Orange safety cones stand around the edge of the sinkhole, suggesting previous human activity, while untouched snow stretches toward distant pine forests under a cloudy winter sky. The mother leopard has thick silver-gray fur with charcoal rosettes, vivid green eyes, and an intensely protective posture as she carefully approaches the dangerous edge. Shot from a slightly elevated cinematic angle with ultra realistic fur, dramatic winter lighting, 8K HDR, National Geographic documentary realism, volumetric light, shallow depth of field, photorealistic textures.
