2018 Map of Logan Ridge

About this map

Logan Ridge serves as the central geological spine of this landscape, separating the more complex western terrain from the expansive flats of the Central Valley Sacramento Valley. The artificial geometry of the Tehama-Colusa Canal cuts a distinct line through the eastern sections, providing a stark contrast to the meandering natural drainages like Hunters Creek and North Fork Logan Creek. In the south, the map illustrates the boundary between Glenn and Colusa counties as it crosses Antelope Valley. The rural character is defined by a grid of local infrastructure, including Road 65 and Noel Evan Road, which link the various drainages and agricultural sections. This survey documents the intersection of natural watercourses, such as Baker Slough and Funks Creek, with the modern irrigation systems that support the regional economy.
