North of Sugar Pine Point there are also several.
_They are all marked by moraine ridges running down from the summits and projecting as points into the Lake_.
The pathways of three of these glaciers I studied somewhat carefully, and after a few preliminary remarks, will describe in some detail.
Mountains are the culminating points of the scenic grandeur and beauty of the earth.

They are so, because they are also the culminating points of all geological agencies--igneous agencies in mountain _formation_, aqueous agencies in mountain _sculpture_.

Now, I have already said that the mountain peaks which stand above the Lake on every side are highest at the southwestern end, where they rise to the altitude of 3000 feet above the lake surface, or between 9000 and 10,000 feet above the sea.

Here, therefore, ran in the greatest glaciers; here we find the profoundest glacial sculpturings; and here also are clustered all the finest beauties of this the most beautiful of mountain lakes.
I need only name Mount Tallac, Fallen Leaf Lake, Cascade Lake, and Emerald Bay, all within three or four miles of each other and of the Tallac House.

These three exquisite little lakes (for Emerald Bay is also almost a lake), nestled closely against the loftiest peaks of the western summit ridge, are all perfect examples of glacial lakes.
South of Lake Tahoe, Lake Valley extends for fifteen miles as a plain, gently rising southward.
