Chumash STEAM: Part I
A pervasive myth among early European colonists was that Indigenous cultures were primitive and unsophisticated — untouched by “civilization.” This misconception persists to this day through depictions of Native Americans as simple and passive hunter-gatherers.
But here are the facts: Pre-contact Indigenous cultures were innovative and complex and continue to evolve today, having survived against incredible adversity. Today, let’s learn more about the innovation and ingenuity of the pre-contact Chumash, and how these practices have endured to this day.
ASTRONOMY (SCIENCE): Chumash rock art reflects a deep understanding of astronomy. Chumash astronomers (known as ‘alaxlapsh) maintained a 12-month lunar calendar by monitoring the movement of the sun, stars, and planets. For one, certain rock art sites served as solstice observatories, from which astronomers observed the position of the sun on the horizon. Sunrise positions at five equidistant locations over the Temblor Range, for example, allowed astronomers to determine dates for important ceremonies. Astronomers could also determine the time of year, such as the solstice and equinox, by the position of the Big Dipper at sunset due to its proximity to the North Star.
NOW: From an elevated location southwest of Painted Rock in the Carrizo Plain, the Chumash had observed the sun rising directly over Mt. Pinos on the morning of the winter solstice. Today, Mt. Pinos continues to be used for stargazing, and Chumash astronomical knowledge continues to be honored through storytelling.
CULTURAL BURNS (TECHNOLOGY): The Chumash are one of many Californian tribes that practiced cultural burns, a form of land management that involves intentionally setting small fires. Cultural burns mitigated catastrophic wildfires and revitalized the land by fostering sustainable plant growth and biodiversity. These burns cleared the buildup of dead plants and released nutrients such as nitrogen into the soil, which promoted the seed and bulb production of plants used for food, medicine, and basket materials. This plant growth also provided food for herbivores, such as deer, that the Chumash hunted.
NOW: In 2023, members of the Chumash community gathered at UC Santa Barbara’s North Campus Open Space for a fire-lighting ceremony. After being outlawed by Spanish colonizers in 1793, this was the first cultural burn in the region in over 200 years.
TOMOLS (ENGINEERING): The construction of tomols was specialized and highly sophisticated. The Chumash were the first in the Americas to develop the plank canoe, which could be 12-30 feet long and 4 feet wide, holding 8-12 people at most. These canoes allowed the Chumash to catch larger deep water fish and cross the Santa Barbara Channel to trade. Tomols were primarily made from redwood driftwood, due to its relative lightness and durability. Wood with a straight grain and no knots was carefully selected; larger pieces of wood were split, and planks were then shaped with stone tools, leveled, and finished with sharkskin. Stone hand drills were used to drill holes in the planks, which were then fitted together and binded with milkweed fiber string. Yop, a caulking made of hardened asphaltum and pine pitch, sealed the cracks between the planks.
NOW: Chumash communities continue to construct tomols today. Each fall, Chumash community members paddle 23 miles across the Santa Barbara Channel to Limuw (Santa Cruz Island) to honor and reclaim their maritime heritage.
