A diamond from Arkansas, a whale bone from Maine, a New Mexican bolo tie, and an iPhone 17 Pro Max are among the items Americans in 250 years will remember today’s U.S. citizens by.

America250, the nonpartisan organization in charge of the country’s semiquincentennial celebrations, released the items that will be stored in its time capsule buried in Independence National Historical Park. The organization will seal the capsule on July 4 and bury the package in the park in Philadelphia with the intent that it will be reopened in another 250 years in 2276.
