The ground is white. The day is June 10. It has been snowing for the past four days in the Bitterroot Mountains. Wayne Fairchild is getting worried about our trek over the Lolo Trail95 miles from Lolo Montana to Weippe in Idaho, across some of the roughest country in the West. Lewis and Clark were nearly defeated 200 years ago by snowstorms on the Lolo. Today Fairchild is nervously checking the weather reports. He has agreed to take me across the toughest, middle section of the trail“but with this weather?When Lewis climbed atop Lemhi Pass, 140 miles south of Missoula, on Aug. 12, 1805, he was astonished by what was in front of him: “immense ranges of high mountains still to the West of us with their tops partially covered with snow”. Nobody in what was then the US knew the Rocky Mountains existed, with peaks twice as high as anything in the Appalachians back East. Lewis and Clark werent merely off the map; they were traveling outside the American imagination.Today their pathway through those mountains holds more attraction than any other ground over which they traveled, for its raw wilderness is a testimony to the character of two cultures: the explorers who braved its hardships and the Native-Americans who prize and conserve the path as a sacred gift. It remains today in virtually the same condition as when Lewis and Clark walked it.The Lolo is passable only from July to mid-September. Our luck is holding with the weather, although the snow seeps getting deeper. As we climb to Indian Post office, the highest point on the trail at 7,033 ft., the drifts are 15 ft, and up. We have covered 12 miles in soft snow, and we barely have enough energy to make dinner. After a meal of chicken and couscous, I sit on a rock on top of the ridge. There is no light visible in any direction, not even another campfire. For four days we do not see another human being. We are isolated in a way that mixes fear with joy. In our imagination we have finally caught up with Lewis and Clark.1.We learn from the passage that before 1805（ ）.2.Judging from the context, the word “trek” (Line 3, Para. 1) is closest in meaning to （ ）.3.We learn from the passage that the Lolo Pass（ ）.4.Judging from the context.
