Overview

Roche Harbor is a sheltered harbor on the northwest side of San Juan Island in San Juan County, Washington, United States, and the site of a resort of the same name. It is listed as a census designated place (CDP). Roche Harbor faces Haro Strait and the Canada–United States border. The harbor itself provides one of the better protected anchorages in the islands. The harbor is surrounded on the east side by San Juan Island, on the north side by Pearl Island, and on the west and south sides by Henry Island. Most of the harbor is 35 to 45 feet deep. Roche Harbor has a small airport used primarily by local residents.

James Charles Prevost in 1857–60, and scouted the area for an ideal site for the British Royal Marines encampment. British Marines quarried and processed limestone at or near Roche Harbor. After the territory dispute was settled in 1872 in favor of the United States, the land encompassing Roche Harbor was homesteaded by Joseph Ruff, 1872–78, and afterward owned by Israel Katz, 1878–79; and brothers Richard and Robert Scurr and their business partners, Alexander, Colin and Donald Ross, 1879-1886. (Katz was a Port Townsend merchant and future mayor of that city who during the joint military occupation established stores in Friday Harbor, Argyle, and San Juan Town, near the U.S. military encampment.) Limestone was quarried at the higher-elevation source, delivered by rail to chutes and dropped into the kilns, and the processed lime removed and bagged or barreled within a short distance from the…
