1910 Map of Grand Hogback

About this map

The striking geological formation of the Grand Hogback dominates this 1906 survey, creating a sharp natural divider between the river valleys of the western slope. Settlement is concentrated along the southern corridor where the Denver and Rio Grande railroad tracks follow the Grand River, connecting towns like Rifle and Newcastle. The map reveals the early transportation network of Garfield and Rio Blanco counties, including isolated outposts like Dinner Sta and the community of Rio Blanco.
