Keep Mammoth Lakes Unreal at Trashy Thursdays

September 30, 2026

Help keep our backyard beautiful by volunteering to pick up trash.

For the 6th year, Mammoth Lakes Tourism partnered with the Town of Mammoth Lakes, Mammoth Mountain, Mammoth Disposal, Mammoth Lakes Recreation, and the United States Forest Service for Trashy Thursdays. This year's events took place on the last Thursday of the month, June through September and each pick up included a complimentary dinner for volunteers.

Join us again next summer 2027 to clean up the community. Trash pickers, bags, and gloves provided. For tips on minimizing your impact year-round, see our guide to camping and recreating responsibly in Mammoth Lakes. Locations rotate, so make sure you check the schedule for each date's location.

Trashy Thursdays Schedule

The 2026 season of Trashy Thursdays has wrapped up! This year, volunteers contributed over 400 hours and collected 768.2 pounds of trash and 141 pounds of recycling. The new format, which condensed the series into four larger events, was a huge success: volunteer hours more than doubled compared to last year.

Thank you to all the volunteers and partners who made it possible. Check back next summer for the 2027 schedule!
