In partnership with the Yosemite Climbing Association, the National Park Service puts on this five-day event each September, in celebration of National Public Lands Day. In 2019 over 2,000 volunteers cleaned up 16,429 pounds of debris from the park. The 2020 event was a virtual celebration, challenging participants to Act Local in their own communities. In 2021, the event was modified and held partly in-person, with 771 participants. Yosemite had over 1,300 volunteers in 2022 and 1,501 volunteers in 2023. Last year in 2024, 1,337 volunteers served over 7,000 hours and cleaned up 13,112 pounds of debris in the park! Y
