INTRO

This is a remote but fun climb in southeastern Washington that begins at Boggan's Oasis at the bridge over the Grande Ronde River. This climb has many bends and turns and some valid hairpins (arguably 22) and is a very fun descent.  

Input from our friend Bruce Hamilton:  "We jumped in the river after the ride as it was really hot there in August. It’s a pretty ride with no traffic – very remote. No trees – just the prairie or the Palouse as it’s known in SE Washington. There is another climb up from the river on the Oregon side and we did them both in the same day."
Average grade is 5.1%.  41% of the climb is at 0-5% average grade and 55% is at 5-10%. The steepest quarter-mile is 7.4%.
