As they descended on the northeastern side, suddenly their sight was arrested by a lake slumbering in a little basin that had been scooped out of the granite sides of the mountain. It is almost immediately under the vertical cliffs, and so clear that the observer seems to look through it, as he would through a looking-glass, upon great walls which appear below, but are in reality reflections of the precipice examined when making the ascent. Lily Mountain was in bold outline on the right, where reposed another lake of somewhat greater size, whose water appeared to feed a stream that ran gamboling down a deep gorge into the plain which it nourished. On every side there were evidences of glacial erosion, not only in the form of bowlders and debris, but in lateral moraines, where the glacier had left deposits, and in gorges where great granite blocks had been tumbled, over which in places the water cantered and fell in beautiful sheets. In one place, towards the base, were found many small aspen trees cut down, and most frequently the trunks were divested of their bark, and the tender limbs were missing. Investigating the cause, it was directly discovered to be the work of beavers, several of whose dams were perceived in a creek that ran through a beautiful meadow land, but no one of the party was able to catch sight of the wary animals. Our party being satisfied with their trip in the park, and especially with the ascent of Long’s Peak, where they had secured more than a score of magnificent photographic views, returned to Loveland to be rejoined by at Fort Collins, as will be presently described. ------------------------------------------------------------------------ [Illustration: MOUNTAIN OF THE HOLY CROSS, COLORADO.] ------------------------------------------------------------------------ [Illustration: GRAYMONT MOUNTAIN, MIDDLE PARK.]
