Broken Top has been on my list for a few years. Trip reports vary in difficulty, so I finally had the chance to check it out solo.
From Green Lakes TH I hike / jogged (hogged?) to Green Lakes in about an hour. From there the trail cuts between the lakes and then steepens. The trail up the Northwest Ridge saddle is sandy and steep. I took a break in the saddle to refuel for the steep ridge climb.
