Whaler Island, about 700 feet (215m) across, lies 0.4 miles (0.65km) offshore and is now connected to the mainland by a paved road on an artificial breakwater, about 16 miles (26km) north-northwest of Klamath and 1.4 miles (2.3km) southeast of Crescent City, California. Whaler Island, together with Lighthouse Jetty, forms a small protected harbor for Crescent City. The island is named after a historical shore whaling station that operated from around 1855 to 1857. The coastal geology mainly consists of the Battery Formation, which formed during the Late Pleistocene and includes marine terrace deposits with dune sands and alluvial gravels. Offshore islands, including Whaler Island, are composed of rocks from the Franciscan Complex, which formed during the Jurrasic and Cretaceous periods, or 150 to 66 million years ago. The Franciscan Complex is an assemblage of metamorphosed and deformed rocks that developed before the San Andreas Fault, when an ancient oceanic trench existed along the California continental margin. This trench resulted from the subduction of the Farallon tectonic plate beneath the North American Plate. The offshore rocks consist of tectonically disrupted blocks of graywacke, shale, conglomerate, chert, limestone, phyllite, greenstone, and serpentinite. Whaler Island is primarily greenstone, with some felsic tuff and pillow basalt, which were quarried to supply rock for constructing and reinforcing harbor breakwaters. In 1939, a rubble-mound sand barrier was constructed to connect Whaler Island to the shore. This barrier was 17 feet (5 m) wide at the crest, with an elevation of about 10 feet (3 m), and an armor layer of stones protected the ocean side. By 1946, the breakwater was rebuilt with an elevation of 18 feet (5.5 m) to protect a small-craft basin. Over the years, the breakwater connecting Whaler Island to the mainland has been significantly widened and reinforced. Today, it is over 160 feet (50 m) wide and regularly used by vehicles. Facilities include a public boat launch and a U.S. Coast Guard station. The outer breakwater, or Lighthouse Jetty, was built in 1957 with 1,836 twenty-five-ton tetrapods. The main stem is 3,670 feet (1,120 m) long, and the easterly extension is about 1,000 feet (305 m).

The Native American culture of northwest California is considered the southernmost extension of the Pacific Northwest culture and is thought to have originated relatively recently, as the existing ethnic groups migrated into the area no later than 1,000 years ago. The Tolowa people inhabited the northwestern corner of present-day California and are connected with the Athabascan tribes of Oregon to the north. Historically, they were hunter-gatherers, relying primarily on deer, fish, and the acorns of the tanoak tree. Like most tribes of the Pacific Northwest, personal value was heavily based on material wealth and social prestige. Prestige could be acquired through shamanship, and a wise shaman often became wealthy. Wealth was measured by material possessions, such as dentalium shells and bird scalps, and extended to the value of human life. Since wealth was inherited patrilineally, materialistic competition led to economic social stratification, with aristocrats enjoying living standards not available to others. The ownership of slaves, or bondmen, was a significant manifestation of exploitation, as they could be manipulated, bought, or sold at the owner’s discretion. Poor people often sold themselves into slavery to pay debts or gain a wife. The first European American to explore this region was pioneer Jedediah Smith in the early 19th century. The arrival of large numbers of Euro-American prospectors, timbermen, and settlers in the 1850s brought devastation to the coastal tribes. The Tolowa and the coastal Yurok were either killed, succumbed to diseases, or dispersed to various reservations. The Tolowa population numbered about 1,000 at the time of Euro-American settlement; by 1910, it had reportedly dwindled to about 150. Today, over 1,000 Tolowa are members of the federally recognized Tolowa Dee-ni’ Nation, Elk Valley Rancheria, Confederated Tribes of Siletz, Trinidad Rancheria, Big Lagoon Rancheria, and Blue Lake Rancheria.

Shore whaling was a profitable commercial enterprise along the California coast in the 1800s. Whaling stations existed from north to south at Crescent City, Trinidad, Bolinas Bay, Half Moon Bay, Pigeon Point, Santa Cruz, Monterey Bay, Carmel Bay, Point Sur, San Simeon, Port Harford, Point Conception, Goleta, San Pedro, and San Diego. The industry was primarily operated by Portuguese immigrants from the Azores and Cape Verde, who had been active on Yankee whaling ships to escape poverty or military service at home. Many crewmen signed on in New England to secure passage to California, lured by the promise of prosperity following the discovery of gold at Sutter’s Mill. Desertion by ship crews at California ports peaked in the late 1840s and early 1850s. When the pursuit of gold proved fruitless, these whalers returned to whaling. Shore whaling was a seasonal pursuit, allowing crews to maintain small farms and family life alongside the excitement of the whale hunt. This lifestyle attracted Azoreans and Cape Verdeans, whose culture also embraced farming and fishing. Early California shore whalers were limited to a hunting range of about 10 miles (16 km) and pursued gray and humpback whales that migrated along the coast. These species migrated at different times: gray whales from December to February and humpbacks from August to December. By taking advantage of both migrations, northern California shore whalers extended their hunting season to eight months each year. The whalers pursued the whales in boats launched from shore. When captured, the whales were towed to the beach and flensed. The fat was rendered in try-pots heated by crude furnaces. At Whaler Island, a small shanty with four compartments served as a washroom, drying room, storeroom, and cooper’s shop. A whaling company typically consisted of a captain, a mate, a cooper, two boat steerers, and eleven laborers. From this crew, two whaleboats were manned with six men each, leaving four on shore to take turns at the lookout station and maintain the try-pot fires. Read more here and here.
