A woman renowned for her mastery of snowy, steep slopes found herself in a very scary tumble down a sharp mountain trail.

Professional freeskier Angel Collinson, 26,  was being filmed for a documentary in Alaska when the snow caught under her, flipping her onto her back.

She plummets down dangerously arduous slopes, seemingly out of control, for what seems like forever before coming to a stop.

Collinson is then seen sitting up, looking understandably dazed but tells everyone that she is OK.

Amazingly, she came out of the massive decent unscathed, suffering only bruises and two jammed fingers, according to CNN.
