This Park is a wilderness. Though entirely surrounded by settlers and villages, it is an almost unbroken wild. Many of its peaks are as yet unclimbed. There are pathless forests, unvisited gorges, unnamed lakes, and unknown localities. Gray and red granite form the larger portion of its surface. Here and there are mixtures of schist, gneiss, and porphyry. The northwest corner is volcanic and is made up of rhyolite, obsidian, and lava. The Indians have a tradition concerning the volcanic activity of Specimen Mountain, though I doubt if this mountain has been active within a century. It is a dead or sleeping volcano. A part of its old crater-rim has fallen away, and brilliant flowers cover the cold ashes in the crater. Most of the territory was glaciated during the last ice age, and there still remain five small glaciers and a number of ice-fields. The Hallett Glacier is on the north shoulder of Hague's Peak, the Sprague Glacier on the south side of Stone's Peak, Tyndall Glacier between Flat-Top and Mt. Hallett, and Andrews Glacier in a cirque of Loch Vale, while an unnamed small one is at the bottom of the east precipice of Long's Peak. There can hardly be found a greater and more closely gathered area of imposing, easily read glacial records than those which centre about Long's Peak. These works of the Ice King, both intact and partly ruined, have attracted the attention and study of a number of prominent geologists and glaciologists. Among these ice works Dr. Hayden and Dr. David Starr Jordan have climbed and wandered. Vernon L. Kellogg has here gathered material for a book, and Dr. Edward L. Orton, former State Geologist of Ohio, has spent many weeks here in study. Within a six-mile radius of the top of Long's Peak are more than thirty glacier lakes and perhaps twice as many lakelets or mountain tarns. Immediately south of the Peak, Wild Basin is literally filled with glacier-records. To the north is Moraine Park; to the northwest, Glacier Gorge and Loch Vale; to the west, lying between the Peak and Grand Lake, there is a wondrous area of the Ice King's topography. Bierstadt, St. Vrain, and Mills Moraines are imposing deposits of glacial débris. Of these Mills Moraine has been the most studied. It apparently holds the story of two widely separated ice ages. This moraine evidently was formed by the glacier which made the basin of Chasm Lake. It extends eastward from Long's Peak, its uppermost end being at twelve thousand five hundred feet. At timber-line its trend is toward the southeast. It is about one mile wide, five miles long, and in places apparently more than one thousand feet deep.
