Washington’s Goldendale Observatory, perched on the Columbia Plateau, celebrated its golden anniversary on October 14—the same day as the recent annular solar eclipse.

The Goldendale Observatory is a Washington State Park Heritage Site and houses one of the largest publicly accessible telescopes in the nation. The observatory and telescope have attracted hundreds of thousands of sky-watchers since 1973.

Over a period of six years in the 1960s, four amateur astronomers (along with help from students and staff at Vancouver’s Clark College) built a 24.5-inch Cassegrain telescope. Vancouver, with its typical western Washington cloudy weather and big-city light pollution, was not a good fit for a serious observatory.

The four telescope builders went on scouting trips to find a home for their 24.5-inch baby. A chance stopover at a local diner in Goldendale, with its beautifully dark skies and often clear weather, led to a conversation with a fellow diner, which led them to meet the town’s mayor. Success--hands were shaken. The telescope was donated after the town agreed to build a public science center to house the instrument and work to maintain those beautiful dark skies from light pollution. The building, with its large telescope, opened in October 1973.

The grand opening of the Observatory was not the first time that Goldendale had been front and center for an astronomical event. In June of 1918, William Wallace Campbell, director of the Lick Observatory in California, visited Goldendale to observe a total solar eclipse. He was part of a team that was using the eclipse to test Einstein’s theory that the sun’s gravity could bend light. 

Although the team was unable to get the data they needed because of cloudy weather (and also because Campbell’s gear was stuck in Ukraine due to World War I), Campbell did make some successful calculations on that 1918 trip to Goldendale. At the request of Sam Hill, noted “good road” promoter, monument-builder, and founder of the nearby Maryhill Museum, Campbell calculated the exact spot where the sun would rise during summer solstice at a site near the museum. That information was used as part of Hill’s design for the Stonehenge replica, a memorial he built for Klickitat County men who died during WWI. (As a sidenote, Campbell traveled to Australia in 1922 to observe a total solar eclipse. That program was successful, and the team confirmed Einstein’s theory. Shoot: Washington state came so close to being the location where Einstein’s theory was confirmed.)

From 1973 through 1980, the Observatory had its ups and downs, primarily because of financial difficulties. But 1979 saw a surge of interest when thousands of visitors arrived for a solar eclipse. That event gave the struggling venture a much-needed financial boost. NBC News even made a donation so that it could broadcast live from the Observatory during the eclipse. Soon enough, though, finances became an issue again, and Washington State Parks acquired the Observatory in 1980, making it one of the largest publicly accessible telescopes in the nation.

Over the years, telescopes have been added at the Observatory, and the primary telescope has been repaired, overhauled, and enhanced. In 2016, it was reconfigured as a Newtonian reflector, which improved the telescope’s ability to serve astrophotography. In 2018, the observatory was temporarily closed when much of the original observatory building was replaced with an expanded facility. During that shutdown, educational programs were relocated to nearby Stonehenge until the upgraded observatory was reopened in 2020 (then closed again during the coronavirus pandemic).

Dark Sky Controversy

In 2010, the International Dark Sky Association awarded the Observatory Dark Sky status, one of the few certified International Dark Sky Parks in thew world, according to the Friends of the Goldendale Observatory. This designation was due to the efforts of long-time Observatory administrator, Steve Stout, along with local amateur astronomers. The Dark Sky status was in keeping with the original agreement given to those four builders of the telescope, who not only wanted an educational science building to house the telescope, but a guarantee from the city and the county on keeping light pollution from affecting the ability to gaze into the heavens from the Observatory.

Who knew this prestigious designation would be the cause of so much trouble, described by some as a “hot button issue.” The Dark Sky designation comes with strict requirements. Turns out anti-regulation activists stepped in, and Washington State Parks said they could not hold up their end of the agreement for dark skies…in part because parks staff cannot “behave in an activist or legislative capacity.” The Dark Sky designation for the Goldendale Observatory was rescinded in 2017.

The Observatory’s website states that efforts to maintain a dark sky continue, with Park, city, local business, and community leaders working to maintain the dark through installation of dimmable LED streetlamps and other activities. The Friends of the Goldendale Observatory group has a different viewpoint on their efforts. To learn more about International Dark Sky Places, visit International Dark Sky Places.
