At this junction you can follow Trail Creek Lakes Trail which leads to the beautiful alpine Trail Lakes. There are three different lakes with great camp spots, but be aware that this is an old burn zone. So there is not too much shade neither along the trail nor at the lakes. The Trail Creek Trail however leads you either to Grandjean Trailhead or Observation Peak, Stanley Lake or Sawtooth Lakes in the other direction.
