All 143 Proposed National Parks, State by State

Proposed National Parks across the country, what has been tried at each, and where each one stands.

Every place here deserves national protection. The tiers describe what kind.

Tier 1National Park

A vast, one-of-a-kind landscape that deserves to be a National Park.

Tier 2National Monument

A landscape that deserves greater protection, on a smaller or less singular scale than a Tier 1 place: the scale of a National Monument.

Tier 3Smaller national site

A smaller place, or one defined mostly by what people built there, that deserves national protection as a monument, historic site, battlefield, memorial, or preserve.

Where a campaign is underway, the place sits in the tier that matches what the campaign is seeking.
