Chinook Pass, Washington, actually, is cleared of its winter-long accumulation of 20 feet of snow. A massive road clearing job amid some of America s noblest vistas. Very deep snow and at the bottom of 40 feet you see a huge snow plow, blower and crane. MCUS - A tractor with a huge shovel on it digging out the snow. MSRV - A car is driving through the cleared out pass.
