Operation 9-2-99 Cleanup

Our illustrious trail boss, Chris Guptil is hosting a clean up day on the North bank of the Tuolumne River on Saturday, October 14, 2023. This is an opportunity for you and your family to give back to our trail system and provide some much needed love to beautifying this area.

If you are on the Modesto Composite MTB Race Team, please let us know and we will add your time to our Teen Trail Corp hours. These count for the entire team so get out there and get your gloves dirty!

  • The clean-up is from 9:00 AM – NOON.  
  • Meeting place is at the corner of 100 10th St. and S. Morton Blvd. under the 9th St. Bridge on the north bank of the river.
  • This cleanup requires a lot of walking and the terrain can be rough, steep, slippery or hard to access but is mostly flat.  We need a large number of volunteers for this cleanup effort.  

We want Operation 9-2-99 to be successful in accomplishing our goals and for our volunteers to enjoy the experience of doing their part to reduce blight and improve our community.  We do not target people or their possessions.  Our focus is on cleaning up what has been left behind, abandoned, or illegally dumped.  Please consider the following guidelines as a volunteer to ensure a safe environment for everyone.
