Decided that for this trip up Baldy, I would take the route-less-traveled ????.  I took Register Ridge up to backbone.  That is one FIERCE trail.  Looking at my AllTrails splits, the 1st mile is 1700ft elevation gain, followed by the 2nd mile of 1200ft gain.  That only gets you up to Devil's Backbone under Mount Harwood – still had another 700ft of gain up to Baldy.  We needed some food at that point to recharge, and were thrilled to see a little family of mountain goats to enjoy while we ate.  We were so close, we decided to summit Mount Harwood on the way to Baldy, then on up to the summit.  We took Ski Hut back down for an 8.25 mile/4100ft gain day.  Little patches of snow here and there, but nothing that presented a problem.
