Earth Day

Saturday, April 20 @ 9:00 am - 12:00 pm

| Free

The creation of Earth Day on April 22, 1970 marked what many consider to be the birth of the environmental movement. Today it is regarded as the largest civic event in the world. Marin residents have embraced it since the first Earth Day celebrations began. Let’s keep up the good work, Marin! Join us to clean up Corte Madera Creek and Hal Brown Park at Creekside; be part of the fun and the Earth Day legacy!

All ages and skill levels are welcome, and no previous experience is necessary; anyone under the age of 18 must be accompanied by a supervising adult or complete an Advance Consent Form (available upon request). Volunteer work is mildly strenuous and involves bending, pulling, and kneeling and hiking on steep and uneven terrain.

In the event of heavy rain and/or high winds call (415) 763-2977 to find out about event status. In the event of cancellation, program will be rescheduled.
RSVP’s are appreciated but not required.
