Did about an 8 mile loop with a Mazama group hike to learn this route. It started and ended at the Memaloose rest Area on the interstate and went about the Old Scenic Highway crossing it in two different locations. My flower count was 40 different flowers. The lower part of the trail was rich with prairie stars,buttercups,parsley and camas as well as bighead clover. The upper areas were full of lupine and balsamroot in full bloom as well as paintbrush, death camas, broomrape, shooting stars and many others.
