I began and ended my run at the ranger station/hiker sign-in at the AMR road entrance. From there, I ran the route as described in the original entry: Gil Brook Trail to Colvin, over to Blake, back over Colvin, then on to Nippletop and Dial. I finished by going over Bear Den and Noonmark Shoulder, following the HG Leach Trail back to the AMR road.
The terrain is classically ADK: completely chaotic rock/scrambling, boulder hopping, and mud bogging. Things ease up after Nippletop, so save some leg for the trip down.
