Sesquisemiquincentennial is a mouthful, but it marks a once-in-a-lifetime moment.
In 2026, the United States will commemorate the 250th anniversary of the Declaration of Independence. At the same time, Colorado will celebrate the 150th anniversary of its admission to the Union. As the Centennial State, Colorado is uniquely positioned to observe both milestones — a combined sesquisemiquincentennial.
To guide these twin anniversaries, the America 250–Colorado 150 Commission was established to ensure all Coloradans can participate. The commission encourages communities across the state to reflect on shared history, recognize diverse experiences, and imagine Colorado’s future through educational programs, storytelling initiatives, and statewide celebrations.
In recent weeks, the commission has highlighted several initiatives, including historic preservation and statewide storytelling, an educational film series titled “The Land We Call Home,” a Colorado statehood online exhibit with classroom resources, publications focused on Colorado history, and the Digital Passport Program, “Journey Through Colorado.” More information is available at Am250CO150.org.
One of the signature projects is “Moments That Made Us,” a marquee exhibition opening Nov. 21, 2025, at the History Colorado Center in Denver and running through Oct. 18, 2026. The exhibition features more than 50 artifacts spanning eight centuries and explores pivotal moments that shaped the nation — including both achievements and failures in living up to founding ideals. Artifacts originate from sites such as Mesa Verde, Jamestown, Valley Forge, Appomattox Court House, Washington, D.C., Ebbets Field and even the moon. The exhibition was developed in collaboration with the Colorado State Historian’s Council and Tribal representatives.
Recognizing that travel to Denver is not feasible for all communities, History Colorado created a print-on-demand version of the exhibit, allowing smaller institutions to select relevant panels and add local context.
The White River Museum will participate by curating panels from “Moments That Made Us” that reflect the unique history of the White River Valley and surrounding communities. Those displays will be available to the public throughout the year.
In addition, the White River Museum has been selected to host the Smithsonian traveling exhibition “Americans.” Based on a major exhibition at the National Museum of the American Indian, “Americans” examines how American Indians have shaped the nation’s identity — from place names and popular culture to historical narratives that continue to influence public understanding today.
The museum is currently developing local business partnerships and sponsorships to support the installation of printed panels. Volunteers will also be needed to serve as docents and assist with building projects, including painting and organizing, in preparation for the yearlong displays.
Those interested in volunteering may contact the White River Museum at 970-878-9982. An application process is required, and staff will follow up as preparations continue.
