Geography
Rogers Pass is a narrow valley surrounded by a number of mountains. It is formed by the headwaters of the Illecillewaet River to the west and by the Beaver River to the east. Both of these rivers are tributaries of the Columbia River, which loops about 240 km around to the north of the pass. It was named after Major Rogers who first surveyed the pass.
Rogers Pass is known for its winter snowfall, which amounts to about 10 m per year. Because of steep mountains, avalanches are very common in winter. When the railway first went over the pass, 31 snow sheds with a total length of about 6.5 km were built to protect the railway from the avalanches. Snow sheds for the Trans-Canada Highway were built later, including large ones in 1962. To keep the Highway open during the winter, the Royal Canadian Artillery uses 105 mm howitzers to knock down the avalanches under controlled circumstances so traffic is not caught in unexpected avalanches.

Famous quotes containing the word geography:
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—Ralph Waldo Emerson (1803–1882)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“Yet America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.”
—Ralph Waldo Emerson (1803–1882)
