🔶 FIXES in CCR documents — several corrections were made from the 1995 USGS Map Name Index for Colorado:

  • The “Hot Sulphur Springs” map. On the USGS Map Name Index for Colorado, it is incorrectly spelled “Hot Sulpher Springs” (grid number 744).
  • The “East of Rock Creek” map. On the USGS Map Name Index for Colorado, it is incorrectly spelled “East of Rock Creeek” (grid number 1712).
  • Grid Number 1090 — “Chalk Bluffs SW” is shown on the USGS Map Name Index for Colorado. In 1997, the USDA Forest Service renamed this map to “Eastman Creek South” and updated it.
  • Grid Number 1122 — “Chalk Bluffs SE” is shown on the USGS Map Name Index for Colorado. In 1997, the USDA Forest Service renamed this map to “Eastman Creek SE” and updated it.
