About this map

Lyman sits at the heart of an intricate irrigation network along the Wyoming-Nebraska border, where the High Plains landscape is transformed by a dense system of canals and drains. The North Platte River flows through the northern reaches, feeding essential water into arteries like the Tri-State Canal and the Mitchell and Gering Canal. This reliance on water management is evident in the numerous named ditches and laterals, including the Packer Ditch and Springer Lateral, which define the agricultural economy of the region.

Prominent landmarks such as Rattlesnake Hill and the northern edge of Table Mtn provide topographic relief against the grid of county roads. Small settlements and local points of interest like Henry and Sears are linked by these thoroughfares, while water bodies such as Packer Lake and Little Moon Lake serve as distinct focal points. The map meticulously documents the transition from the river valley to the elevated plains, capturing the intersection of natural hydrology and human engineering.
