Goldendale Observatory State Park

Goldendale Observatory State Park is a 5-acre educational park with an awesome telescope, located atop a 2100ft-elevation hill. It's undergoing renovations, so programs have been moved to the nearby Maryhill Stonehenge Memorial site, which is exactly what it sounds like. Programs here will involve portable telescopes and outdoor viewing; dress warmly.
