How old is the Salish Sea? Salish Sea is the name given to the inland sea in the Pacific Northwest of North America, including the Strait of Georgia, Puget Sound, and the Strait of Juan de Fuca. It is approximately 200 miles long and 90 miles wide, with a surface area of 6,000 square miles. The Salish Sea is home to a diverse range of marine life, including salmon, orcas, and seals.

The Salish Sea was formed by the retreat of glaciers during the last ice age, approximately 10,000 years ago. As the glaciers melted, they carved out the deep basins that now make up the Salish Sea. The Salish Sea is a relatively young body of water, compared to other bodies of water in the world, such as the Atlantic Ocean or the Pacific Ocean.

The Salish Sea is an important part of the Pacific Northwest ecosystem. It provides habitat for a variety of marine life, and it is also a major transportation route. The Salish Sea is also a popular destination for recreation, including boating, fishing, and kayaking.

The Salish Sea is a beautiful and important body of water. It is a reminder of the power of nature and the importance of protecting our environment.
