Decision Point

Decision Point State Marine Park protects a strategic point and anchorage in Prince William Sound near Whittier. The 667-acre marine park marks a navigation decision point where boaters choose their route through the Sound. The park provides protected anchorage and shore access in one of the most accessible portions of Prince William Sound.

Prince William Sound supports exceptional marine wildlife including humpback and orca whales, harbor seals, Steller sea lions, and sea otters. Black bears forage along shorelines while mountain goats may be visible on steep slopes. Seabirds and eagles are abundant throughout the Sound. Salmon runs attract predators in summer.

Coastal rainforest of Sitka spruce and western hemlock covers the slopes above the shore. The understory features typical Southeast Alaska vegetation including devil's club and salmonberry. Recent glacial retreat has exposed new terrain showing plant succession from pioneer species to mature forest.

Prince William Sound occupies a tectonically active region where the Pacific Plate subducts beneath North America. The 1964 earthquake caused dramatic changes including uplift that exposed new intertidal zones. The Sound was carved by glaciers that left the complex topography of islands, passages, and fjords.

Maritime climate brings mild temperatures moderated by Gulf of Alaska waters. Summer temperatures range from 50-65°F while winters stay relatively mild. Precipitation is substantial, with rain possible any day. Weather can change rapidly, and boaters should be prepared for fog and squalls.

Chugach peoples have navigated Prince William Sound for thousands of years. The Sound was transformed by the 1989 Exxon Valdez oil spill, which released 11 million gallons of crude oil. Recovery efforts continue, and the disaster remains a defining event in the Sound's modern history.

Decision Point State Marine Park was established as part of the marine park system protecting strategic locations in Prince William Sound. The park provides public access to a key navigation point used by recreational boaters throughout the Sound. It helps maintain wilderness character in the accessible portion of the Sound.

The protected anchorage serves boaters and kayakers exploring the Sound. Shore exploration offers rainforest hiking and beach walks. Wildlife viewing opportunities are excellent throughout the Sound. The park's accessible location makes it a popular first stop for trips originating in Whittier.

The marine park provides anchorage accessible by boat or kayak from Whittier. Whittier is connected to the road system via the Anton Anderson Memorial Tunnel. Charter boats and water taxis operate from Whittier. No developed facilities exist in the park; visitors should be prepared for wilderness conditions.

The marine park protects shoreline and marine environments from development. The park contributes to ongoing recovery efforts following the 1989 oil spill. Sustainable recreation practices help maintain the Sound's natural values while allowing public access.
