Flyer with information on the 2023 National Public Lands Day Volunteer Event

Join Us for National Public Lands Day!!

Join JCOS, and our partners Adams County, City of Wheat Ridge, City of Golden, and City of Arvada, for our BIGGEST volunteer event of the year, National Public Lands Day! On Saturday, September 23, from 8:00 a.m. - 2:00 p.m., we will be cleaning 19.5 miles of the Clear Creek watershed. All ages welcome. After the cleanup, we will celebrate at Anderson Park in Wheat Ridge with food trucks, live music, and a raffle. 

Participants will be working along the Peaks to Plains Trail adjacent to Clear Creek and other tributaries. Past efforts have resulted in the collection of 38,870 pounds of trash. Mismanaged trash that escapes into waterways can create a wide range of problems. Aquatic trash affects water quality, endangers plants and animals, and pollutes the outdoor spaces that we depend on for tourism and recreation. 

Trends toward increased visitation, changing climate conditions, and the spread of invasive species are challenges that public land managers are facing throughout the country. Your volunteer time is essential to helping preserve our natural areas for water quality, wildlife habitat, and recreation, now, and into the future. Thank you for Volunteering!
