Day of Action

June 3, 2017

Our national monuments, marine protected areas, and public lands are the storytellers of the shared histories and the diverse communities that make this country great. A significant number of the monuments covered under the Executive Order: Review of Antiquities Act and National Monuments ordered by President Trump represent designations made under the Antiquities Act by previous presidents to celebrate the diverse people and places that have contributed to our nation’s history. During this time, we must demonstrate support of our national monuments all across the nation.

Let the Administration know that our national monuments matter to you. On June 3rd, join Next 100 Coalition members and allies at a national monument (or any public lands) near you to show support for the cultural history preserved in these spaces. Show up, take a selfie, and post it with a message about what these natural treasures mean to you. 

Find an event near you listed below or create your own event and get outdoors on June 3rd!

To submit an event to this site, use our Contact page. Please provide your name and organizational affiliation (if any), contact information, which monument you will be visiting for the Day of Action, and other details about your event that you think would be helpful for those who hope to join you. The list of national monuments under review is available on the Department of Interior’s website, and a list of all national monuments is available on the National Park Service website.

June 3rd is also American Hiking Society’s National Trails Day. At least one dozen hikes will take place in a national monument. Find out if there’s a National Trails Day event at a national monument near you by clicking here, or search all National Trails Day events here.

If you can’t get outside on June 3rd, submit comments to Secretary Zinke to let him know why these special places are important to you. Comments on Bear Ears National Monument are due by May 26th and comments on all other monuments under review are due by July 10th. You can also wear or carry your support by getting #DefendOurMonuments gear here!

Biscayne National Park

Homestead, FL

Title: Defend Our Monuments Day of Action at Biscayne National Park
Description: “I like the name Monument. It means that things are going to stay pretty much as they are today,” said Sir Lancelot Jones, 1970, when he sold his ancestral island in Biscayne Bay to the National Park Service. His one request was that he be allowed to live out his life on the island. Today it has been expanded into Biscayne National Park, among the largest marine units in the National Park System. Come learn the story of this pioneering black family. Enjoy breathtaking ocean views and go for a paddle if you like.
