By that time they would be well into the prodigious mountainous region which would confront them for a thousand miles or more, for it is the foothills of the Rockies. The present state of Colorado is traversed by the main axis or continental divide of the Rocky Mountains which there finds its greatest northern development. The culminating crest of the main range is the Wind River Mountains in the west-central part of the State, which is traversed by numerous other ranges, including the Big Horn in the north-central section, the Laramie Mountains already mentioned, the Medicine Bow in the south; north of them the Sweetwater and Rattlesnake ranges, and in the west the Teton, Shoshone and Gros Ventres mountains. The extreme northeast is penetrated by the Black Hills from South Dakota. The loftiest peak is Fremont’s in the Wind River Mountains, two and a half miles high, with others of almost as great elevation. The Wind River Mountains display that remarkable fact which is probably familiar to our readers. Rain falling in a comparative brief area divides so that some of the drops flow westward and find their way into the Columbia and thence to the Pacific. Another part of the rainfall or melted snow winds its way ultimately to the Colorado and into the Gulf of California, while a third gropes to the Missouri and finally into the Gulf of Mexico. The southeastern part of the State, through which our friends were journeying, is drained by the North Fork of the Platte and its affluents, including the Laramie and Sweetwater rivers, the Lodge Pole, Rock, Poison Spring, Medicine Bow, Horse and Rawhide creeks. It may be added that that grand national playground known as the Yellowstone Park covers a wide area in the northwestern corner of the State. One of the most deceptive things is distance on the plains and among the mountains. Alden Payne was certain of reaching the base of the Laramie range before the company went into camp at nightfall, but as the afternoon drew to a close, the wild region seemed as far off as ever. “If all goes well we shall strike ’em by to-morrow night,” commented Shagbark; “howsumever ye have observed that another company has camped two miles off on the same creek that we’re going to use.” “Is there any possibility of its being the one that Mr. Chadwick is with?” asked Alden. “Shouldn’t be ’sprised, but thar ain’t no way of telling without making a call.” “I think I shall ride over just before dusk and find out.” “Nobody’ll object to that; will ye go alone?” Alden hesitated. His first intention was to ask Shagbark to accompany him, but the uncertainty of his sentiments caused the youth to decide otherwise. He would take Jethro, for companionship, rather than for any help he could give. Shagbark made no comment on the decision, and it is not likely he cared one way or the other.
