A papier-mâché crab holding bronze-cast crackers. Meticulously detailed aquatint etchings of oyster shells. These are a few of the items featured in West Marin’s newest tool-shed-turned-art-gallery in Marshall, the Lonely Abalone. The space is located across the street from Hog Island Oyster Company and the gallerists are a group of California College of the Arts graduates who are chasing childhood nostalgia on Tomales Bay, driven by what they call a re-energized arts movement in West Marin. “It feels like there’s a bit more energy—like more of a connection and momentum out in West Marin than there has been in the last 10 years,” said Marshall native Connor Wishard, who bought the property five years ago. The oyster company used the tool shed as an office space before artists Jack Cram and Cianna Valley started renting it from Mr. Wishard. Last weekend’s sunny weather allowed for the gallery’s first official pop-up. “It was really beautiful,” Mr. Cram said. “Lots of people showed up and it was just a very awesome event.” Mr. Wishard’s childhood is filled with memories of places on the East Shore. His parents were married at the now-derelict Marshall Tavern and his father built a sailboat that he moored south of Marshall. Mr. Wishard spent his first five years in a small cabin next to the Marshall Store but moved to Sonoma when it was torn down. Five years ago, he bought the plot of land across from the oyster company, and although there’s no home there yet, the Lonely Abalone represents a return that he hopes will become more permanent. “We always wanted to find a way back, so when we had an opportunity to get that shack and some land, we took it. We’re hopeful about building something,” he said. Ms. Valley, a printmaker, and Mr. Cram, a sculptor, attended C.C.A. in the late aughts. He spent his formative years exploring the wonders of Tomales Bay and feels a deep connection to the area. Since he lives in the East Bay, the new gallery offers a fresh incentive to revisit West Marin more frequently. Like most local galleries, the Lonely Abalone isn’t a cash grab, but a way to show their work and support their network of artist friends. “It’s a great property and it’s amazing how many people in the area are artists,” Mr. Cram said. The Lonely Abalone’s next pop-up will take place in March and feature a series of masks from different artists. Learn more on Instagram at @theonlylonelyabalone.
