The designation "Northeast," which the Parker-Browne party put upon the ridge that affords passage from the lower glacier to the upper, is open to question. Mr. Charles Sheldon, who spent a year around the base of the mountain studying the fauna of the region, refers to the _outer_ wall of the Muldrow Glacier as the Northeast Ridge, that is, the wall that rises to the North Peak. Perhaps "East Ridge of the South Peak" would be the most exact description. But it is here proposed to substitute Harry Karstens's name for points-of-the-compass designations, and call the ridge, part of which the earthquake shattered, the dividing ridge between the two arms of the Muldrow Glacier, soaring tremendously and impressively with ice-incrusted cliffs in its lower course, the Karstens Ridge. Regarded in its whole extent, it is one of the capital features of the mountain. It is seen to the left in the picture opposite page 26, where Karstens stands alone. At this point of its course it soars to its greatest elevation, five or six thousand feet above the glacier floor; it is seen again in the middle distance of the picture opposite page 164. Not until this book was in preparation and the author was digging into the literature of the mountain did he discover the interesting connection of Arthur Harper, father of Walter Harper, narrated in another place, with Denali, and not until that discovery did he think of suggesting the name Harper for any feature of the mountain, despite the distinction that fell to the young man of setting the first foot upon the summit. Then the upper glacier appeared to be the most appropriate place for the name, and, after reflection, it is deemed not improper to ask that this glacier be so known. It has thus fallen out that each of the author's colleagues is distinguished by some name upon the mountain except Robert Tatum. But to Tatum belongs the honor of having raised the stars and stripes for the first time upon the highest point in all the territory governed by the United States; and he is well content with that distinction. Keen as the keenest amongst us to reach the top, Tatum had none the less been entirely willing to give it up and go down to the base camp and let Johnny take his place (when he was unwell at the head of the glacier owing to long confinement in the tent during bad weather), if in the judgment of the writer that had been the wisest course for the whole party. Fortunately the indisposition passed, and the matter is referred to only as indicating the spirit of the man. I suppose there is no money that could buy from him the little silk flag he treasures. It was also while this book was preparing that the author found that he had unwittingly renamed Mount Brooks, and the prompt withdrawal of his suggested name for that peak left the one original desire of naming a feature of the mountain or the range ungratified, and his obligation toward a revered memory unfulfilled.
