Volunteer
Help make it happen.
It takes a community.
Mariposa 250 is entirely volunteer-staffed. We need 178 volunteers across 20 task categories to make July 4 work. Whether you have a morning, an afternoon, or the full day, there’s a role for you.
How it works
- Tell us a bit about yourself and which tasks interest you.
- We’ll contact you within a week to confirm your role, shift, and any training required.
- Show up on July 4 ready to work — we’ll provide a t-shirt, meal vouchers, and our eternal gratitude.
