Avalanches Make To Order High in the Wasatch Mountains a state park both with summer and winter wonderland. Snow avalanches are a natural process but at times forest rangers have to execute controlled avalanches to minimize the greatest of spring dangers in the mountains. A CU shot stating that its a slide area and to keep off. Two Forest Rangers plant the dynamite and push the plunger and Boom! The avalanche starts coming down the mountain side. Quite a sight. Even in black and white the area is beautiful.
