To the southward of the Laramie Plains is the Colorado North Park, among the mountains of that State, having an area of over two thousand square miles. Beyond, the railway route goes westward among hills and over the plateaus. This route is not as picturesque as some of the other Pacific railways, but in crossing the Continent it discloses very curious scenery. At places there are great Buttes, water-worn and rounded, rising in isolated grandeur; the plains and terraces are carved into elongated and wide depressions, as if abandoned rivers had run through them; there are long and regular embankments, strange hills of fantastic form, huge mounds, broken-down pyramids, vast stone-piles, and the most strange and extraordinary fashionings of nature, showing both water and fire to have been at work. Then the route passes the snow-clad Uintah Mountains to the southward, and crossing the Wahsatch range, enters Utah, traversing its remarkable enclosed basin, where the waters have no outlet to the sea, but flow into salt lakes which lose their surplus supplies by evaporation in the summer. Beyond, is the wild and picturesque Echo Canyon, with the green valley of Weber River and the Weber Canyon. Here is the gigantic Castle Rock, a rugged stone-pile fantastically carved by nature, having a giant doorway and all the semblance of a mountain fortress. Here is also the "One Thousand Mile Tree," on the northern side of the road, being that distance west of Omaha. In the Echo Gorge is the Hanging Rock, where Brigham Young, as the Mormon Pilgrims journeyed to their Utah home, is said to have preached the first sermon to them in the "Promised Land." The old-time emigrant trail passes through these canyons alongside the railway and the river. A remarkable sight within the Weber Canyon is the Devil's Slide, where on the face of an almost perpendicular red mountain, eight hundred feet high, there is inlaid a brilliantly white strip of limestone about fifteen feet wide, all the way from top to bottom, having enclosing white walls, the whole work being as regularly constructed as if built by a stonemason. Beyond, we come to Ogden, a busy industrial town of twenty thousand people, the western terminus of the Union Pacific Railway, and having another railroad leading thirty-seven miles southward to Salt Lake City. GREAT SALT LAKE.
