FR 9215B is a signed two-track that heads east from Hart Prairie Road (FR 151). This road is open to motorized vehicles, but is lightly traveled. The trail heads uphill past a cattle gate (close it behind you) and winds through pine forest.
At a meadow with signs saying "Closed to Motorized Vehicles" look for a well-traveled, but unsigned, connector trail that leads directly to Aspen Corner via Alfa Fia Tank (which usually holds water). Shortly past this intersection FR 9215B dead ends in an aspen glade, where a faint connector leads about 100 yards to the Arizona Trail.
