No towns meet the strict criteria for “Colorado – Wyoming Bordering Towns.”
Understand that asking for towns that sit exactly on or straddle the Colorado–Wyoming state line creates an empty list. Municipal boundaries almost always fall entirely inside one state. The Colorado–Wyoming border is a straight, survey line (the 41st parallel) across mostly rural land. Settlements in this area tend to sit a short distance north or south of that line rather than bisect it.
Know the technical and historical reasons behind this. State and local incorporation rules put towns inside a single state government. Early roads, ranches, and land grants also steered growth away from the precise survey line. Many nearby places are unincorporated communities, ranches, post offices, or highway crossings — not incorporated towns that legally touch the state line. Cross-border towns do exist in other parts of the U.S. (for example, Texarkana), but the Colorado–Wyoming border has no incorporated towns that meet the strict “bordering” test.
Check these useful alternatives instead. Compile towns within a set distance of the line (for example, within 5–10 miles), list towns in the counties that run along the border, map highway crossings and state highways that cross the line, or list nearby unincorporated communities and points of interest. Explore those categories for practical travel, research, or genealogical work instead.
