The trail levels a bit, goes through an Aspen forest before reaching a stone cabin built by actor Lon Chaney. The cabin now serves as a wilderness ranger residence during the summer months. Continue up more switchbacks, crossing the creek twice before reaching a trail junction at 4 miles. Go right for Black Lake, a trail that will eventually bring you back around to Fourth Lake and the trail back down to First Lake. Go straight to reach First Lake at 5 miles.
Second Lake is right next to First Lake, Third Lake is about mile further.
The imposing mountain above Second and Third Lakes is Temple Crag. Third Lake is fed directly from the glacier, causing it's milky turquoise color from the glacial powder carried down from the melting glacier. The trail to Palisade Glacier is about mile above Third Lake. Turn left and follow the switchbacks up among grassy benches and boulders to Sam Mack Meadow. Watch for the sign crossing the creek at the meadow.
