I’ve endeavored to visit each of Arizona’s National Natural Landmarks (often abbreviated as NNLs). Here’s a bit more context on what NNLs are.
Completed
- Barfoot Park
- Barringer Meteor Crater
- Comb Ridge
- Grapevine Mesa
- Kaibab Squirrel Area
- Patagonia-Sonoita Creek
- Willcox Playa
Remaining
Restricted to the public
Unfortunately, this quest includes two objectives that are not open to the general public. So neither are formally part of this quest. I’ll “re-add” either if that status ever changes. 🤞
- Canelo Hills Cienega Reserve (not open to the public)
- Onyx Cave (requires spelunking experience/gear/permit)
