Rattlesnake Ledges have a terrific view of the I90 corridor, up toward the mountains, back down toward Seattle, and across to Mt. Si. I was fascinated to see the flat benches part way up the valley floor. A nice workout, 1600 feet of elevation gain in about 3 miles, this is a nice place to hike at dusk when the full moon rises over the mountains to the north.
On this particular day, I went on beyond the first ledge, to the two further on.
