Project Description

Escape the valley heat when you retreat to the mountains with a PNTA crew on Shedroof Divide TR 512 and Grassy-Hall Divide TR 533. Two teams will maintain the PNT on the ridgelines between Roundtop and Hall Mountains.  

Help clear a path thru the PNT by joining this log out party as a “swamper” who follows behind a PNTA sawyer, rolling log rounds and tossing branches off the trail. Take turns on the end of a crosscut saw as we maintain a corridor through the Wilderness. Crew members also use loppers and handsaws to trim back brush and saplings growing in the corridor, and dirt work tools to repair the tread and clear drains along the way. 

One team will maintain the Shedroof Divide north of Pass Creek Pass, then the PNT portion of Grassy Top TR 503, and the eastern 1-2 miles of Grassy-Hall.  

Another team will work on the western 3-4 miles of Grassy-Hall, and the mountainside section of Noisy Creek TR 588.

No trail crew experience necessary: the PNTA provides tools, personal protective equipment, and training. Just bring yourself, your daypack, and a thirst for a rewarding day on the trail!

About Drop-in Work Parties
“Drop-in” volunteers make a difference by boosting the capacity of a PNTA Performance Crew. The crew works on site for the duration of the trip, but volunteers are welcome to participate for as long as they like.

Meals are available for multi-day participants who register early enough for us to include them in meal plans.  (See Meals deadline in Project Details, above.)

Want to dig deeper and play longer? The Performance Crews work at this location for a full week; reach out to the Project Leader at if you’d like to join the crew on another date not listed in the registry.
