Understanding the Age of the Salish Sea

The Geological Perspective

The age of the Salish Sea, as with any geographical feature, can be understood from a geological perspective. Geology provides tools and techniques for dating the Earth and its features, and in the case of the Salish Sea, scholars refer to geological evidence when they estimate its age. According to geological records, the Salish Sea formed around 11,000 to 12,000 years ago, a figure derived from the study of various rock formations, sediments, and fossils found in the region.

Moreover, such estimates match the chronology of the last Ice Age, suggesting that the Salish Sea was sculpted by glaciers in the region. The advancing and retreating ice packs carved out the sea's basin, and when they finally retreated for the last time, they allowed the sea to fill with water. This provides a timeline placing the birth of the Salish Sea at the end of the Ice Age.

Furthermore, the discovery of drowned forests in the region, preserved under layers of sediment and dating back to post-Ice Age periods, provides additional evidence supporting these geological age estimates. This shows how geologists use a multifaceted approach, combining different types of evidence to come up with a comprehensive age estimate.

The Archaeological Perspective

Secondly, the age of the Salish Sea can be viewed through an archaeological lens, which involves the study of human activity and its relationship with the environment. The archaeological record shows evidence of human habitation along the shores of the Salish Sea dating back at least 5,000 years, and possibly longer.

For example, evidence of ancient fish traps, middens (waste heaps), and shellfish harvesting sites provide a timeline of human interaction with the Salish Sea. Coupled with geological findings, it can be inferred that humans established settlements and began exploiting marine resources soon after the formation of the Salish Sea at the end of the Ice Age.

The continuous habitation and utilization of marine resources indicate a close relationship between the people and the sea, and the sea's pivotal role in their survival, culture, and history. The rich archaeological record underscores not only the region's vibrant past but also bears testament to the ancient roots of the Salish Sea.

The Indigenous Perspective

The last perspective through which to understand the age of the Salish Sea is the indigenous perspective. Indigenous peoples have lived in the region for thousands of years, and their oral histories and traditions provide important insights into the age of the Salish Sea.

Indigenous stories often reference significant geographical features like the Salish Sea and infuse them with cultural and spiritual significance. For example, tales of ancestral journeys, epic battles, and powerful spirits playing out on the Salish Sea suggest a longstanding relationship with the water body that dates back millennia.

This rich cultural narrative allies the age of the Salish Sea with the origins of the region's indigenous people, intertwining human history and geological timescales in a unique way. As such, the indigenous perspective not only offers a different way to consider the age of the Salish Sea but also reflects the lasting bond between the people and their land, waters, and environment.
