This is the mapped route via hourglass ridge. The red line begins at the Lion Lake Trail Junction. This is my favorite route because you get to pass Lion Lake #1, Lion Lake #2 and Snowbank Lake. These are some of the most beautiful, prestine lakes I have ever seen. the wildflowers are amazing, and there is abundant wildlife. I would highly reccomend this route, with a descent via Boulder-Grand Pass.
