Arizona National Natural Landmarks (NNLs)

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

• Onyx Cave
• Ramsey Canyon

Not open to the public

Unfortunately, this quest includes an objective that is not open to the public. So it is not formally part of this quest. I’ll “re-add” it if that status ever changes. 🤞

• Canelo Hills Cienega Reserve (not open to the public)
