Lost Creek and Sand Creek carve through the high plains of Adams County in this late 1940s survey of the Sunnydale area. The landscape is primarily defined by its drainage patterns and the infrastructure of early 20th-century water management, most notably the Henrylyn Canal (Abandoned) in the northern sections. This decommissioned waterway speaks to the shifting agricultural and irrigation priorities of the Missouri River Basin development era.
