On the 125th anniversary of the creation of Yosemite National Park, an icon of California and the federal parks system, Yosemite Valley was graced by a double rainbow.

"A double rainbow was a fitting conclusion to yesterday's celebration of our 125th anniversary," Yosemite National Park wrote in posting this on Facebook on Oct. 2, 2015.
“A double rainbow was a fitting conclusion to yesterday’s celebration of our 125th anniversary,” Yosemite National Park wrote in posting this on Facebook on Oct. 2, 2015.

An image of the double rainbow, posted Friday by the park’s social media accounts, was described as a “fitting conclusion” to Thursday’s celebration of Yosemite’s quasquicentennial.

Yosemite Valley and surrounding areas became a park in 1890, further protecting and expanding land that had first been covered under the 1864 Yosemite Grant Act.

President Benjamin Harrison signed the legislation to create the national park on Oct. 1, 1890, preserving more than 1,500 square miles of largely pristine Sierra Nevada wilderness.

Some 1,500 people attended a celebration of the park’s creation on Thursday.

In marking the occasion, the U.S. Department of Interior tweeted a photo of Yosemite Valley from an overlook.

“125 Years old never looked so good,” the tweet read.
