dating from this time have been found in middens at abandoned camps near the river. Microblades known as atlatl were used from about 7000 years ago to hunt caribou by natives. The first known all-year winter villages weren't constructed until about 2300 years ago; house development and town size to contend with climate change occurred rapidly at around this time. Pottery dating from 2500 years ago has also been found. The first white humans arrived in the 19th century, with the first white man to document the river being the Russian captain Tebenkov in 1852. At the same time, native peoples began leaving the area, with the Alagnak River village being abandoned around 1860. In 1900 the North Alaska Salmon Company built two canneries at the junction of Alagnak and Kvichak rivers. The cannery at the river mouth became known as Lockanok and the other cannery, 1000 feet upstream on the Kvichak River, was called Hallerville, in honor of J.P. Haller, president of the company. The two canneries were connected by a narrow gauge railroad that brought salmon from Hallerville to be processed at the Lockanok plant. The abundance of salmon in the rivers made this fishery one of the most prolific in Alaska. People from as far away as the Yukon River area came to get jobs at the canneries, and before long cash income allowed subsistence users to buy food store items such as coffee, tea, sugar and salt. The 1912 eruption of Mount Katmai nearby only mildly devastated the region and the Yu'pik Indians continued to keep food caches at the site. Growing importance In 1916 Libby, McNeill & Libby purchased both the Lockanok and Hallerville canneries from the North Alaska Salmon Company. Growing erosion around the Kvichak River banks made canning more difficult by the 1920s, and the cannery was closed in 1936 and burned down during a 1937 fire. Any remaining planks of wood from the building were taken to houses along the river and helped to create new homes for the natives. In 1918 the Spanish flu epidemic broke out and ravaged the villages throughout June 1919, killing 39 natives and creating 16 new orphans. Despite the tragedy, villages along the river prospered due to jobs offered by the cannery. After the decimation of natives by the disease, white human settlement around the Alagnak increased rapidly. In June 1927 Russell Merrill of Anchorage Air
