Pure first-person camera perspective, no visible drone, no aircraft, no propellers. The camera races

Pure first-person camera perspective, no visible drone, no aircraft, no propellers. The camera races at extreme speed through a narrow snow-covered mountain pass as a colossal avalanche erupts behind it, swallowing entire cliffs and forests. Massive boulders crash down from above while towering ice walls collapse on both sides. The camera dives beneath falling glaciers, threads through collapsing ice caves, narrowly avoids exploding ice pillars, then bursts through a wall of snow into a breathtaking sunrise above the clouds. Continuous one-take, authentic inertia, violent camera banking, ultra-fast proximity flight, realistic snow physics, volumetric powder explosions, cinematic motion blur, HDR, IMAX-scale, Hollywood blockbuster VFX.
