Looking more southeasterly (downstream) in this view. In extreme southeastern Washington state, pretty much on the Oregon line. The Grande Ronde River rises in the Blue Mountains of northeastern Oregon and flows pretty much east, joining the Snake about where Idaho, Washington, and Oregon come together. It's cut a canyon thru here in Columbia River Basalt--in fact, in the Grand Ronde subgroup of the basalts! The individual basalt flows define the prominent layering in the slopes. The highway runs more or less north-south; SR 3 in Oregon, becoming SR 129 in Washington. It's pretty steep and narrow, and a bit nerve-wracking with a trailer!
