In 2026, the United States celebrates 250 years since the signing of the Declaration of Independence, and Colorado marks 150 years of statehood. Combining these historic events also provides us with a term that may prove a mouthful – Sesquisemiquincentennial!
These milestone twin anniversaries invite us to reflect on our shared history, celebrate our communities, and look to the future together.
Throughout the year, events will take place across the region to commemorate and celebrate this incredible milestone. We invite you to participate, share with others, and feel a sense of pride for the country and state that we live in.
Be sure to bookmark this page, as more content will be added as additional events are planned throughout the region.
As we enter 2026, Colorado invites communities across the state to participate in a once-in-a-generation commemoration. Many events are taking place throughout the state as part of the sesquisemiquincentennial celebration. You can be a part of them too!
The calendar linked below highlights events that celebrate our shared history, culture, and communities.
Moments That Made Us
The Moments That Made Us social media campaign invites community members to share photos and stories that reflect the experiences, traditions, and milestones that shaped who they are today. From family memories to moments of service or personal achievement, these stories help tell the shared story of our County, State, and Nation.
By sharing these moments, we celebrate how far we’ve come, honor our collective accomplishments, and look ahead to a future rooted in unity. Submit your photos and stories to epcpio@elpasoco.com for a chance to be featured on social media and displayed on a community timeline during the El Paso County Fair—helping preserve our history and connect generations.

Bear Creek Nature Center
Celebrating 50 Years
Bear Creek Nature Center is celebrating 50 years of connecting the community to nature as Colorado’s first nature center. Located within Bear Creek Regional Park, the Nature Center’s scrub oak thickets, ponderosa pine forests, meadows, mountain creek, and abundant foothills wildlife have inspired generations of visitors. Year-round interpretive programs, special events, and guided and self-guided experiences support environmental education, conservation, and stewardship.
Two miles of self-guided nature trails wind through short grass prairie, scrub oak woodlands, and cottonwood riparian communities. A regional leader in accessibility, Bear Creek Nature Center pioneered accessible programming such as Trailability and the V.I.P. Trail, expanding access to nature for visitors of all abilities.
