Sources and method

  • Boundary: Colorado Parks and Wildlife, the same layer the WikiHunt map draws.
  • Public land: USGS Protected Areas Database (PAD-US) 4.1, Fee Managers layer (public domain).
  • Method: the unit and PAD-US polygons are simplified to about 100 m and measured on a grid of about 250 cells across the unit, so overlapping records are counted once. Expect about ±1 percentage point.
  • Season dates: WikiHunt’s season table, updated Sep 2, 2026, checked against each state’s published regulations. Dates change; the regulations win.
