Trail Maintenance Groups

The POST Partners Volunteer Program helps organize and oversee four trail maintenance groups in Town - the Ridgeline Wranglers, PSM Trail Partners, Rhyolite Dirt Crew and Keepers of the Rock.

Ridgeline Wranglers

Ridgeline Wranglers is a group of volunteers who help maintain and improve Stewart Trail at Ridgeline Open Space. The group has approximately 40 active members, with five trained crew leaders. The crew leaders have completed background checks, so they are cleared through the Town to work with children. Town staff members lead maintenance outings. 

Work on the trail includes:

  • De-rutting the trail
  • Eliminating berms
  • Clearing scrub oak and other brush that may encroach on the trail 
  • Eliminating noxious weeds
  • Implementing trail improvements

The group meets one Saturday a month at the Ridgeline Open Space trailhead off of Coachline Road, with additional maintenance outings scheduled as needed.

2020 season information

Additional information can be found at the Wranglers’ Facebook group.

Ridgeline Wranglers receive a POST Partners T-shirt and POST water bottle and / or hat, as well as an end-of-season party with raffle prizes and food. Participants interested in becoming crew leaders will receive free training. Email us with any questions.

Rhyolite Dirt Crew

Started in 2010, the Rhyolite Dirt Crew helps maintain and improve the bike park at Rhyolite Regional Park. Additional information can be found on the Facebook group for the Dirt Crew.

In 2012, improvements were made to the bike park berms and jump line, with machine work by Progressive Trail Designs and follow-up hand work by the Dirt Crew. A new mulch practice jump was also added at the base, along with a return. In addition, a new 2-mile permanent cyclocross course was established in fall 2012.

In May 2013, a new session zone with a beginner, intermediate and advanced line was constructed by Progressive Trail Design and the Dirt Crew.

In 2018, Zach Vacura took the helm as our crew leader. A picnic area was added, and the session jumps were reworked to give the course new life. This is hard work, and we appreciate all the volunteers who come out to help! Volunteers receive a POST Partners T-shirt, water bottle and / or hat.  If you are interested in volunteering, email us
