Frost Shop Marketplace is an open-air market on Highway 140 — the scenic route to Yosemite National Park. We host local makers, growers, cooks, and artists Friday through Monday from Memorial Day weekend through Halloween, every year.
I'm Xav Dubois. I started Frost Shop Marketplace because Mariposa needed a real place for its makers, growers, and cooks to sell — not just to each other, but to the millions of people streaming up Highway 140 to Yosemite every season.
For two years I worked on the County permits, the lease, the site plan, the build, the marketing, the software that powers vendor onboarding and booth assignments — most of it in public, most of it without a paycheck — because I believe local economies get healthier when small producers have a stage worth their work.
If you're a vendor here, I'm your founder and operator. If you're a visitor, welcome — what you spend at The Lot stays in Mariposa.
Builds the marketplace, runs the software, manages County + insurance + sponsor relationships, and shows up at The Lot most market days.
The face vendors talk to. Onboards new vendors, answers the day-of questions, runs the floor on market days.
One of the people without whom this lot wouldn't exist. Helps bridge the marketplace to the Mariposa community.

Mariposa is small. Local makers, farmers, and food vendors often have nowhere consistent to sell. Tourists pass through Hwy 140 to Yosemite without ever meeting the people who actually live and create here.
Frost Shop is the missing market — a weekly home for Mariposa's producers, and a doorway for visitors to spend money locally instead of leaving it in the park.
Founded by Xavier Dubois (Ignite Space, Inc.). Operating in transition to a fiscal sponsorship under the Collaborative Arts and Culture Foundation (CACF) — a 501(c)(3) public charity — so vendor fees stay anchored in community reinvestment, not extractive profit.
On the ground: a lean team of one founder plus volunteers and vendor-leaders. Every dollar is accounted for and most decisions are made in public on this site.
