The latest offering from extreme sports film mavens Matchstick Productions introduces us to the wrath of La Niña – El Niño’s colder, rancorous twin sister. La Niña is a five-month period of lower-than-normal temperatures across the surface of the Pacific Ocean. As a result, it snows, and snows, and snows. To most people heavy snow is a nuisance. The Attack of La Niña teaser, edited by Shelby Meinzer, shows what professional extreme skiers do with that “gift” in locations that range from Colorado to British Columbia.
