About this map

The Wenatchee Mountains and Jump Off Ridge dominate the western terrain of this 1920 survey, giving way to a network of ranches and schools that defined early Kittitas County. Along the Columbia River, transport is anchored by the Trinidad Ferry and Haywood Ferry, providing vital crossings before the era of modern bridges. The Great Northern railroad skirts the northeastern bank, tracing the river's edge near Crescent Bar.

A distinct cluster of rural schools, including the Whisky Dick School and Tarpiscan School, indicates a dispersed but organized settlement pattern focused on ranching. Landmarks like Chinamans Hat and Whisky Dick Mtn rise above the gulches and creeks, while the Cascade Ditch reveals the early engineering efforts to manage water in the lower valley for agricultural use. Ranches such as the Morgan Ranch and Coaler Ranch are noted by name, offering a precise look at local land ownership.
