1991 Map of Eureka Hill

About this map

The Point Arena Air Force Station and associated Military Reservation dominate the southern uplands of this coastal California landscape, providing a specialized look at Cold War-era infrastructure in Mendocino County. The terrain is defined by the steep drainage of the Garcia River and its North Fork Garcia River, which cut through a complex network of ridges like Zeni Ridge. Small tributary systems such as Rolling Brook and Lee Creek flow through the interior, while the northern reaches are marked by the headwaters of Brush Creek and its southern fork. The presence of Jacks Opening and the eponymous Eureka Hill suggest localized clearing and historical landmarks within the dense topography. This 1991 provisional edition reflects 1980s aerial data, capturing the footprint of the air station and the surrounding timber and watershed geography before more modern shifts in land management.
