The map segments the contiguous United States into four colored regions: dark blue (Pacific Northwest and Upper Midwest), cyan (Mountain West and Northern Plains), yellow (Southwest and parts of the South Central U.S.), and red (Southeast and Deep South). A prominent green line runs horizontally near the 37th parallel, possibly indicating a climatic, agricultural, or demographic threshold such as the historical Mason-Dixon line extension or USDA plant hardiness zone boundary.
