The Pacific Ocean dominates this tactical chart, revealing the precipitous transition from the sea to the coastal peaks of Humboldt County. Produced by the Corps of Engineers, U. S. Army under Col. Thos. H. Jackson, the map emphasizes the maritime hazards and shoreline topography of the mid-1920s. Along the narrow coastline, distinctive landmarks such as Gorda Rock and Reynolds Rock serve as primary navigation points for seafaring vessels. Inland, the terrain rises sharply toward the summit at Gorda 2365, while drainage is defined by steep ravines including Gorda Cr. and Reynolds Cr.. The inclusion of Spanish Flat indicates a rare area of level ground amidst the dramatic coastal contours, providing a valuable reference point for researchers studying historical land use and early coastal surveying along this stretch of Northern California.
