Leaving Rainbow Curve, the road follows the rim of another deep canyon, passing through a ghost forest, scene of a devastating fire in the 1870’s. Grotesquely formed treeline trees reflect the harsh climate at this high altitude. As the Rock Cabins are passed, a superlative view opens up to the south across Forest Canyon. For several miles the road traverses the Alpine zone tundra, carpeted during July by low-growing, colorful flowers. Glaciated mountains south of Trail Ridge Road can be seen to best advantage from Rock Cut (altitude 12,110). Gorge Lakes, Forest Canyon, and other landscape features are indicated in roadside exhibits. If time permits, a short hike can be made over a nature trail to the nearby Roger W. Toll Memorial Peakfinder. A walk along this trail provides a rare opportunity to become acquainted with the tundra; however, the high altitude affects some people adversely, so it may not be advisable for persons with heart ailments to attempt the trip. [Illustration: Winter snows lie deep at higher elevations of the park.] Iceberg Lake, which occupies a glacial cirque, was named from the presence of blocks of ice that remain on its surface even in late summer, except in extremely warm and dry years. The reddish cliffs at this point are made up of relatively recent lava, which is not common in the park. The highest point (12,183 feet, marked by a sign) is between Iceberg Lake and Fall River Pass. The pass is a popular stopping place, with restrooms, alpine exhibit room, and lunch counter. Below Fall River Pass the road continues downhill all the way to Grand Lake. The Continental Divide is crossed at Milner Pass at an altitude of 10,758 feet, in the midst of a typical spruce-fir forest. As Far View Curve is approached, the valley of the Colorado River comes into view, and the rugged Never Summer Range looms up to the west. The road descends from this point in sharp switchback curves to reach the wide floor of the Colorado Valley. From here to Grand Lake, the route follows the valley. Deer and elk are often seen in this vicinity. The lake itself, over 250 feet deep, is one of Colorado’s scenic gems. The town of Grand Lake, outside the park, is a friendly western town with the usual resort accommodations.
