You can lead tower of teeth and then set up a TR on this and the guardian. or better yet you can lead it. 4 bolts. the crux is going from the 2nd to the 3rd bolt. the crux is a thin traverse and a fall here would be scary, but I don't think it would warrant a pg-13.
From the Sylvan Lake Store head towards the damn and stay left to walk past the house. Start making your way on the trail shooting between DUET and Riddle. As you approach duet turn left and hug the base of the wall that is the Tower of Teeth. the first route you'll see is wast knot. Continue along the base of the wall and locate the route tower of teeth (1st bolt at ground level). Then turn right and up into the small gully. The guardian face is the obvious face between the route tower of teeth and the dihedral (the guardian).
4 bolts. new-ish anchors up top.
