🛰 Real NASA Data. Real Darkness.
The PurpleTents Dark Sky Guides are the only camping tools that use NASA VIIRS 2024 light-pollution data and our proprietary Dark Sky Precision Score™ (DSPS™) to scientifically rank America’s night skies — from pristine Bortle 1 zones to dimly lit urban edges.
🚨 The Discovery
60.0% of all U.S. campgrounds achieve true Bortle 1 “Pristine Dark Sky” conditions.
Forest Service lands dominate the charts — often out-darkening even certified International Dark Sky Parks.
