The Chumash resided between the Santa Ynez Mountains and the California coasts where a bounty of resources could be found. The tribe lived in an area of three environments: the interior, the coast, and the Northern Channel Islands. The interior is composed of the land outside the coast and spanning the wide plains, rivers, and mountains. The coast covers the cliffs, land close to the ocean, and the areas of the ocean from which the Chumash harvested. The Northern Channel Islands lie off the coast of the Chumash territory. All of the California coastal-interior has a Mediterranean climate due to the incoming ocean winds. mild temperatures, save for winter, made gathering easy; during the cold months, the Chumash harvested what they could and supplemented their diets with stored foods. What villagers gathered and traded during the seasons changed depending on where they resided. With coasts populated by masses of species of fish and land densely covered by trees and animals, the Chumash had a diverse array of food. Abundant resources and a winter rarely harsh enough to cause concern meant the tribe lived a sedentary lifestyle in addition to a subsistence existence. Villages in the three aforementioned areas contained remains of sea mammals, indicating that trade networks existed for moving materials throughout the Chumash territory.
