As we continue eastward, we are very much in the rain shadow of the Cascade Mountains. The short grass “Palouse” area was mentioned in the journals of Lewis and Clark for the shortage of wood for their campfires at night. The lush trees we found today were planted and irrigated in Lyons Ferry State Park and in Palouse Falls State Park. Water continued to contribute to our highlights of the day as we traveled to Palouse Falls, where the tumble of water into the massive plunge pool carve about 10,000 years ago by the Bretz Floods continues to impress us. A bookend to the falls, the calm waters of the Palouse River. There we navigated upstream winding our way through cattails, bulrushes and a bit of tree debris left by a busy beaver. In all it was a lovely, crisp fall day to be exploring in the wake of Lewis and Clark.
