The Going-to-the-Sun Road was completed in 1932 and is a spectacular 52 mile, paved two-lane highway that bisects the park east and west. It spans the width of Glacier, crossing the Continental Divide at 6,646-foot-high Logan Pass. It passes through almost every type of terrain in the park, from large glacial lakes and cedar forests in the lower valleys to windswept alpine tundra atop the pass. Scenic viewpoints and pullouts line the road, so motorists can stop for extended views and photo opportunities. The road is well worth traveling in either direction, as the view from one side of the road is much different than from the other. In 1983 Going-To-The-Sun Road was included in the National Register of Historic Places and in 1985 was made a National Historic Civil Engineering Landmark. Glacier National Park was established in 1910. It is a land of mountain ranges carved by prehistoric ice rivers. It features alpine meadows, deep forests, waterfalls, about 50 glistening glaciers and 200 sparkling lakes. The vistas seen from Going-To-The-Sun Road are breathtaking, a photographers paradise. Relatively few miles of road exist in the park's 1,600 square miles of picturesque landscape, thus preserving its primitive and unspoiled beauty enlivened by a spring and summer profusion of wildflowers.
