The trail junction marks the point where you can continue to Rendezvous Pass or the Grizzly Hut. If you have a dog, you can only take the trail to Rendezvous Pass, and not the other trails that are for skiers (i.e. no pets) only.
If this is your midpoint, turn around and cruise the road all the way back to the start of the tour. It is a fast ski with great skating or track skiing based on your preference.
