This is a downstream view of the Palouse RIver below Palouse Falls. The Palouse RIvers empties into the Snake at Lyons Ferry. The Snake RIver flows west from here and, in about 120 miles from Lyons Ferry, it reaches a confluence with the mighty Columbia River at Pasco, which is one of the Tri-Cities in Washington state.
After our walk in Dayton on Friday morning, October 12, 2012, we drove east on US 12, then headed north on Washington 261. We crossed the Snake River at Lyons Ferry. About 6 miles north of Lyons Ferry, we turned off Washington 261 and headed towards Palouse Falls, which lies about 2 miles down a gravel road from the turn-off.
There is one lava layer upon another in eastern Washington. Millions of years ago, repeated volcanic eruptions spread multiple layers of the lava across hundreds of square miles of the western North American continent.
