هروب على زلاجة ثلجية عبر نهر جليدي

A woman in her mid-30s wearing a heavy arctic survival suit races across the deck of a massive icebreaker ship cutting through frozen seas. Behind her a towering wall of collapsing glacier ice crashes into the ocean. At the 2-second mark she jumps onto a snowmobile and accelerates toward the bow ramp as the ship tilts from the impact. The snowmobile launches off the ramp and lands on a drifting iceberg. Camera drone captures the small vehicle racing across floating ice fragments while the glacier collapses behind. Arctic ocean chaos, snowmobile iceberg landing, collapsing glacier wall, icy debris explosions, cinematic realism, 4K.
