In terms of sheer elevation, this might be the most impressive slam dunk ever by a high school player.

Hafid Yassin, a 6-5 senior at Chief Sealth High in Seattle, is looking down at the rim at the highest point of his jump, and then throws down a one-handed slam on an inbounds-pass alley-oop. Caution: One of the fans on the video reacts quite enthusiastically, so set your volume level accordingly.

Yassan led his team with 13 points and six rebounds in a 96-55 loss to Garfield.

Greg McCorkle, a photographer for the West Seattle Herald, snapped a great picture of Yassin's dunk for the opposite angle of the video. To see it, click here.
