Reading edition
About to the ultimate forks of Grape cr. The S. end of the Wet Mountain valley is a sort of pocket where the Wet mts. connect with the Sangre range by intermediate elevations (as Promontory Bluffs, etc.). Creeks come into the valley from the E., S., and W., converging to compose Grape cr., the ultimate tributary of which is now known as Cottonwood cr. The border of this pocket, on the S., is the boundary between Custer and Huerfano cos.—an irregular line continuing on the W. along the main ridge of the Sangre range, and on the E. along that ridge of the Wet mts. which divides sources of Hardscrabble cr. and St. Charles and Greenhorn rivers from those of the Huerfano.
