Catherine Creek is located between the towns of Lyle and Bingen on the Columbia River. It is part of the Columbia River Gorge National Scenic Area.
Driving east on Hwy 14 is a bit of an adventure. Once I got outside of Vancouver, I experienced the winds the Gorge is famous for. The two lane highway is full of bends and twists and very soon you start climbing to the Cascades. While the mountains are not as high here owing to the effect of the river upon the geology, higher mountains are very near and snow is present in many bare areas. Across the river you can see waterfall after waterfall. The drive from Portland to Hood River is famous for the number of waterfalls. Unlike the Washington side, the Oregon side of the river supports and Interstate which is fast level and an easy option for those in a hurry.
In a very short time you can tell you are in "eastern" Washington. Pine trees show up in the woods and balsamroot flowers dot the roadside. In Bingen the hills look nothing like one sees in western Washington.
I will say however, for the best flowers one should climb and ramble in the area across the road. There were many groups of folks present. Hikers and photographers. A group of students from an Oregon college and many people with dogs.
