1958 Map of Manor Slough

About this map

Antelope Valley and the western foothills of Colusa County are defined here by a series of north-south ridges and steep draws, including Boxer Valley and the transition through Sulphur Gap. Along the base of these hills, the small settlement of Mountain House sits at a junction where Antelope Creek and Freshwater Creek emerge toward the flatlands. This 1958 survey captures the intricate water management of the valley floor, where the Glenn-Colusa Canal and Danley Lateral intersect with natural drainage like the Glenn Valley Slough. Local roads such as Mills Orchards Road and King Road connect scattered farms and pumps to the small community of Manor, illustrating the area's mid-century reliance on irrigation to transform the arid landscape into productive agricultural land.
