The beauty of Oregon's Williamette Valley is on full display in this fantastic drone video by top contributor Michael Roth. The 240 km (around 150 mi.) long valley follows the Wiliamette River as it runs roughly northwards toward Portland (Oregon's largest city and the second-largest in the Pacific Northwest) and from there to its confluence with the mighty Columbia River. Locations featured in the video include Mt. Jefferson, Opal Lake, Davey Lake, Salt Creek Falls, Detroit Lake, and Clear Lake.
