Toward daylight the bears got up and walked a few times round the cabin. On each round they clawed at the door, as though to tell Sullivan that they were there, ready for his hospitality. They whined a little, half good-naturedly, but no one admitted them, and finally, just before sunrise, they took their departure and went leisurely smelling their way down the trail. Mountain Parks and Camp-Fires The Rockies of Colorado cross the State from north to south in two ranges that are roughly parallel and from thirty to one hundred miles apart. There are a number of secondary ranges in the State that are just as marked, as high, and as interesting as the main ranges, and that are in every way comparable with them except in area. The bases of most of these ranges are from ten to sixty miles across. The lowlands from which these mountains rise are from five to six thousand feet above sea-level, and the mountain-summits are from eleven thousand to thirteen thousand feet above the tides. In the entire mountain area of the State there are more than fifty peaks that are upward of fourteen thousand feet in height. Some of these mountains are rounded, undulating, or table-topped, but for the most part the higher slopes and culminating summits are broken and angular. Altogether, the Rocky Mountain area in Colorado presents a delightful diversity of parks, peaks, forests, lakes, streams, cañons, slopes, crags, and glades. On all of the higher summits are records of the ice age. In many places glaciated rocks still retain the polish given them by the Ice King. Such rocks, as well as gigantic moraines in an excellent state of preservation, extend from altitudes of twelve or thirteen thousand feet down to eight thousand, and in places as low as seven thousand feet. Some of the moraines are but enormous embankments a few hundred feet high and a mile or so in length. Many of these are so raw, bold, and bare, they look as if they had been completed or uncovered within the last year. Most of these moraines, however, especially those below timber-line, are well forested. No one knows just how old they are, but, geologically speaking, they are new, and in all probability were made during the last great ice epoch, or since that time. Among the impressive records of the ages that are carried by these mountains, those made by the Ice King probably stand first in appealing strangely and strongly to the imagination. All the Rocky Mountain lakes are glacier lakes. There are more than a thousand of these. The basins of the majority of them were excavated by ice from solid rock. Only a few of them have more than forty acres of area, and, with the exception of a very small number, they are situated well up on the shoulders of the mountains and between the altitudes of eleven thousand and twelve thousand feet. The lower and middle slopes of the Rockies are without lakes.
