Two of the peaks rise almost to fourteen thousand feet. One of these I had the honor to dedicate, with the consent of my associates, to Mr. P. P. Whitfield, the distinguished palaeontologist of Albany, New York. This remarkable peak, of which the eastern aspect is represented in the following figure by Mr. Young, rises to a height of 13,985 feet, as determined by triangulation. It is pyramidal in outline, composed of sedimentary rocks, varying in color from dark gray to dull red and maroon, and almost horizontal along the face, so that, taken in connection with its surroundings, it is probably the weirdest object in this portion of the chain. On its southern side rises a similar pyramid, reaching to an equal height, while adjoining it on the north, a long arched comb gradually rises, stretch- ing to within a hundred feet of the level of its summit. Its northeasterly face is hollowed out so as to resemble a huge pointed scoop rising two thousand feet above the glacial cup below. On its western side the mountain shows itself a noble pyramid, whose face rises sharply and unbroken at an angle of [From: Hart, John Lathrop Jerome: "Fourteen Thousand Feet: a history of the naming and early ascents of the high Colorado peaks."
