Sesquicentennial, Semiquincentennial. These tongue twisters have been seen and heard frequently in 2026 as the United States honors the 250th anniversary of the signing of the Declaration of Independence and Colorado celebrates 150 years of statehood. In Superior we’ve added 130 to the numerical array recognizing that the Town of Superior was platted by William Hake in 1890 and officially founded in 1896. Although not described in a single word, it seemed appropriate to include this important date in the history of Superior and Colorado.
Colorado Territory graduated to statehood when President Ulysses Grant signed a bill making Colorado the 38th state in 1876. Since it was the 100th anniversary of the Declaration of Independence, the nickname “Centennial State” was born.
Aug. 1 is feted as “Colorado Day,” which historically meant that towns across the state celebrated our inclusion in the Union on that date. Boulder’s Pow Wow Days are a local example. That special day featured a hard rock drilling contest, a dance, picnic, and rodeo and, of course, a Pow Wow Rodeo Queen. Starting in its inaugural year of 1934, the event was first called the Boulder Pay Dirt Pow Wow. The parade down Pearl Street ended at the Pow Wow Grounds, located between 28th and 30th streets north of Mapleton Street in Boulder.
Not only is Aug. 1 Colorado Day but since it is the first Saturday of the month, it also means the Superior Historical Museums will be open to visitors. The Historical Commission invites you to stop by either or both Museums:
Come see the progress we’ve made with our collections and displays. In addition, the Town’s historic fire truck will be on display at the Grasso Museum, weather permitting.
This event will feature special fun! After your visits to the Asti Park Historical Museum and the Grasso Park Interim Museum, celebrate Colorado Day at Grasso Park with the Historical Commission, featuring:
