Cutts Island Marine State Park is a small island park in Carr Inlet of southern Puget Sound โ€” accessible only by boat or kayak. The park is part of Washington’s unique system of marine state parks โ€” a network of island and shoreline parks that provides boaters and kayakers with camping and recreation along the intricate waterways of Puget Sound. Puget Sound is one of the world’s largest estuaries โ€” a 100-mile-long fjord carved by glaciers during the last Ice Age. The Sound’s cold, nutrient-rich water supports over 200 species of fish, 100+ species of seabirds, and iconic orca whales.

Frequently Asked Questions

How was Puget Sound formed?

Puget Sound was carved by a massive glacier (3,000+ feet thick) during the last Ice Age โ€” the ice sheet advanced south from Canada and gouged deep troughs in the bedrock. When the ice melted 15,000 years ago, seawater flooded the troughs, creating the Sound. The result is a fjord-like inland sea โ€” 100 miles long, up to 930 feet deep, with 1,332 miles of shoreline.
