There is a program within the National Parks Service that works on land that is not necessarily part of the parks system. In fact, not all of the land is even public.

The National Natural Landmarks Program includes almost 600 sites around the country, 10 of which are in Arizona. Each of those in the state is in this month’s edition of Arizona Highways Magazine.

Heather Eggleston, acting manager of the National Natural Landmarks Program spoke about the sites.
