The Grande Ronde River is my favorite of all time. The wildlife safari. Wild and Scenic River requires firepan and portable sanitation. Clean and gorgeous camp sites. Great vegetation types. It is remote in a deep canyon. Few roads.
We put in at Minam and took out at Boggan's Oasis in Washington State. About 78 miles in a week. It was at 3000-5000m cfs. A deep canyon.
We took rafts. Lots of drift boats. Few canoes except experts. Bighorn sheep, elk crossing the river, and bald eagles all day long. I took a nap and woke with a fawn staring at me from 8 feet.
