Sunset ignites the clouds around Mount Rainier’s summit in Mount Rainier National Park in Washington. To see this, hike up to Glacier Overlook and enjoy wonderful views of forests, meadows, streams, mountains and wildlife. There’s so much to experience, you might even miss the marmots. Can you spot the one in this picture? Photo by Howard Snyder. Posted on Tumblr by the US Department of the Interior, 5/22/16.
