(Bryce, UT) — One of Utah’s most popular national parks is celebrating a milestone. The National Park Service says they are celebrating the 100th birthday of Bryce Canyon National Park this week. It was originally established as a national monument in 1923, then established as Utah National Park before being changed to its current name. A centennial celebration has already been held but NPS wants visitors to continue celebrating with other events throughout the year. Numbers show more than two-point-three million people visited the park last year.
