High Point

Muddy/snowy at the summit with some soft spots occasionally. All can be avoided still and with the fall weather, It was surprisingly dry. I took a wrong turn and did cobblestone loop by accident and turned onto Stealth also by accident. My app shut down and I got lost. Navigation is not my forte on the trail. I wish it were easier to understand the directions.. Not all trail forks indicated direction well.

Once you get to the Beaver Dam if climbing from 24-7 (Clockwise), it turns into a real mud swamp. Before that, it's great.
