#palousefalls the final entry in our #channeledscablands road trip. This 200ft waterfall was also created during the big flood that created dry falls.
Layered basalt cliffs surround a waterfall. Green water is flowing down the river. The sky is totally blue. Grass lines the foreground.

More about the big flood during the ice age: It created the #channeledscablands as it scoured part of eastern and central Washington. It left behind towers, cliffs, lakes, and hillocks of rock-similar to shapes you might see made by sand on a beach. #basalt see alt text.
A basalt mesa called Castle Rock rises above a grassy pasture. There are ponderosa pines off to the side. The sky is blue with cirrus clouds. A trail goes up the flank to the basalt tower which can be climbed in one specific place and if you are willing to walk the plank on the far side! This is on private property. I’ve roamed this area since I was a kid, thanks to my relationship with the owners. View from the top of Castle Rock. Between scattered trees, bright green hillocks contrast with dry grass. A basalt cliff can be seen in the background and the rolling Palouse Hills in the distance. The hillocks were formed by floodwater. Gorgeous blue sky and wisps of clouds. Rock Lake in Whitman County, Washington seen from the top of the mesa. This 7 mile long lake is the largest lake created during the flood. It is 375feet deep and only accessible at the southern end. It is surrounded by private property. A black, white and brown Australian Shepherd is near the edge of the cliff. The lake is blue between basalt cliffs. Layers of basalt can be seen across the shore with grassy areas between them. There is sagebrush and dry grass on top of the mesa. Blue sky, and a curl of a cirrus cloud to the left. Another view from the top of Castle Rock with fainter hillocks below, Rock Lake in its canyon to the right, and a smaller lake, Castle Rock Lake, in a basalt walled pothole to the left.The sky is blue with a few wispy white clouds. The lake can be seen far in the distance near the horizon.

Paddleboarding a lake carved by lava and glaciers?

Yes please.

Williams Lake is one of Eastern WA’s hidden gems—peaceful waters, basalt cliffs, and tons of osprey.
