BEYOND THE OFFICIAL 21
The useful map is bigger than the certified map.
These additions are clearly labeled as independent recommendations or research targets. They are here because a real road trip should not ignore a worthwhile night-sky place just because it falls outside the official list.
Boulder
A useful near-Denver night-sky stop with a long lighting-ordinance history and easy access to foothill darkness.
X02INDEPENDENT ADDITIONKim / Southeast Colorado dark country
Remote southeastern Colorado can reach extraordinary darkness even though it is not built as a conventional tourism stop.
X03FIELD LOGGEDLoveland Pass
A dramatic high-elevation night-sky detour close enough to Denver to be tempting and remote enough to feel completely different after dark.
X04INDEPENDENT ADDITIONPawnee National Grassland
An eastern-plains detour with huge horizons and personal significance as one of the places I loved stargazing growing up.
X05INDEPENDENT ADDITIONUNM-Taos Observatory
A cross-border astronomy detour worth watching when a southern Colorado road trip continues into northern New Mexico.
