As its speed increased, I now and then caught a glimpse, through flying, pelting snow-particles, of shooting rocks which burst explosively through the top. At timber-line the gorge walls abruptly ended and the channel curved swiftly to the left in a broad, shallow ravine. The momentum of this monster carried it out of the ravine and straight ahead over a rough, forested ridge.
Trees before it were crushed down, and those alongside were thrown into a wild state of excitement by the violence of swiftly created and entangling gale-currents. From the maelstrom on the top I looked down upon the panic through the snow-dust-filled air and saw trees flinging their arms wildly about, bowing and posturing to the snow. Occasionally a treetop was snapped off, and these broken tops swirled wildly about, hurried forward or backward, or were floated upward on rotating, slower currents. The sides of the slide crumbled and expanded; so it became lower, flatter, and wider, as it slid forward on a moderate up grade. A half-mile after leaving the gorge, the slide collided at right angles with a high moraine. The stop telescoped the slide, and the shock exploded the rear third and flung it far to right and left, scattering it over a wide area. Half a minute later I clawed out of the snow-pile, almost suffocated, but unhurt.
Toward the close of my last winter as government “Snow Observer” I made a snowshoe trip along the upper slopes of the Continental Divide and scaled a number of peaks in the Rocky Mountains of central Colorado. During this trip I saw a large and impressive snow-slide at a thrillingly close range. It broke loose and “ran”–more correctly, plunged–by me down a frightful slope. Everything before it was overwhelmed and swept down. At the bottom of the slope it leaped in fierce confusion from the top of a precipice down into a cañon.
