About this map

The Wenatchee Mountains and the high desert canyons of Kittitas dominate this 1922 edition, which captures the era's reliance on isolated ranching and localized schooling before modern road networks. Settlement is concentrated along the western valley floors and the banks of the Columbia River, where the Trinidad Ferry provided a critical crossing point. High-elevation landmarks like Colockum Pass and Jumpoff Ridge overlook a landscape carved by numerous drainages, including Tarpiscan Creek and Whisky Dick Creek.

A distinct pattern of rural life is visible through the distribution of family-named holdings and civic outposts. Ranches such as Sheridan, Mountain Home, and Osborn are scattered across the foothills, supported by a network of one-room schoolhouses like Upper Naneum School and Whisky Dick School. The eastern boundary is defined by the river and the Great Northern and Quincy Railway, while the interior remains a domain of seasonal trails like the Gate Trail.
