About This Waterfall
Grand Union Falls is one of a seemingly countless number of waterfalls along Eagle Creek in Oregon's Columbia River Gorge. The falls roll over a segment of the ubiquitous columnar basalt in the area and plunge 41 feet into a large pool. The falls can be seen from the Eagle Creek trail through the trees, but are not easily photographed from the trail unless the trees are bare - climbing down to the creek is necessary for a clear vista. Near the falls the trail passes over a section known as The Potholes - columnar joints that have been sculpted into bowl shapes by dripping water.This waterfall has been called Blue Grouse Falls in all editions of A Waterfall Lover's Guide to the Pacific Northwest, but the more accepted local name of Grand Union Falls or Grand Junction Falls, after the confluence of the east and west forks of Eagle Creek immediately upstream, is the proper title.
