Patos Island Marine State Park provides a favorite campsite for paddlers and moorage for sailors, located on the northernmost edge of the San Juan Archipelago, noted for its historic lighthouse and wild, remote shores.

A Rocky Island

The San Juan Islands are distinct from most of Puget Sound in that they feature shorelines with exposures of hard bedrock, rather than the bluffs of clay, sand and gravel left by Ice Age glaciers that are predominant on most of Washington’s Salish Sea, the state’s inland saltwater passages.

Saint Edward State Park hugs the shore of Lake Washington, the second largest natural lake in Washington, surpassed in area only by Lake Chelan. Tongues of the great Pleistocene glaciers that excavated the passageways of Puget Sound also dug the nearly 20 mile long basin of Lake Washington. For thousands of years, the lake received fresh water from the Sammamish River at its north end and drained through the Black River into Puget Sound at its south end.

Between the Mountains and the Sea

Dosewallips State Park features extensive tidelands at the mouth of the Dosewallips River on Hood Canal. Erosion of the Olympic Mountains to the west combined with the steep gradient of the river carries a large quantity of sediment downriver. Silt, sand and gravel are deposited by the river when it reaches the flatter terrain in the park, naturally braiding its riverbed with many channels as it flows towards Hood Canal. The large fan of sediment and mud at the river’s mouth has long been a rich estuary.

"Its grim black walls of basalt frown across a broken chain of linear lakes, some of them as wide as the coulee floor ….. potholes a hundred feet deep in rock, dry cataracts one hundred to four hundred feet high, and river bars one hundred to two hundred feet thick … under the present semiarid climate it lies naked of forest mantle, every detail of its form clearly displayed." -J Harlen Bretz, Geologist

State Parks’ professional arbor crew blends science, technology and tree work for public safety and conservation.

“What is your earliest tree memory?” Washington State Parks Arborist Mik Miazio once asked visitors at Millersylvania.  

Most recalled climbing trees or eating fruit from neighboring orchards. Grandparents’ houses and childhood backyards were common themes.  

Trees and forest ecosystems are among Washington’s icons, and many nature lovers equate the outdoors with trees. 

And a brief accounting of the hard work that has made it amazing!

By Kelsey Lang, Interpretive Specialist, Fort Worden State Park

My oh, my! It’s been a busy fall, winter and spring at the Commanding Officer’s Quarters Museum. But before diving into recent developments, let’s rewind a bit. On January 1, 2024, Fort Worden State Park officially assumed operations of the museum from its previous steward, the Jefferson County Historical Society.

A Rain-fed River Runs Through It

Bogachiel State Park hugs the bank of the Bogachiel River (locally known as the “Bogie”) on the northwestern reaches of the Olympic Peninsula, providing recreational opportunities on the windward slope of the Olympic Mountains. Storms and moisture rise as they are forced up over the Olympic Mountains from the Pacific Ocean. When the moist air rises, it expands and cools. The colder air is less able to hold moisture, so clouds and precipitation form. Bogachiel State Park averages over 120 inches of annual precipitation!

Ginkgo Petrified Forest State Park preserves a swath of semi-arid shrub-steppe in central Washington that hides a secret. Buried within the gravelly and sandy soils of the park’s landscape are remnants of an ancient forest, turned to stone by a fortunate convergence of geologic events.

Flood Basalts and Lahars

Ginkgo Petrified Forest lies near the western margin of the Columbia River Basalt Group, a geologic formation made up of hundreds of distinct lava flows that flooded over 80,000 square miles of Washington and Oregon.

“Islands are still the domain of the explorers, the adventurers, the discoverers.”  --Alexander L. Bond, conservation biologist

Jones Island Marine State Park, an entire island off the southwest corner of Orcas Island in the San Juan Archipelago, offers each visitor a chance to connect with their inner adventurer. Its hills rise nearly 200 feet above a low isthmus. Rock outcrops on its rugged shore reveal that the bedrock of the island was formed deep on the ocean floor and uplifted above the water’s surface by the forces of plate tectonics.

The 31-mile Klickitat State Park Trail hugs the meanders of the Klickitat River and its tributary, Swale Creek, revealing stories of massive volcanic flows, bubbling mineral springs, timeless Indigenous subsistence traditions, ephemeral attempts at wresting profits from the land, and a delightful environment of oak and pine woodlands and grasslands. The trail stretches from a windswept plateau 1,600 feet above sea level to the river’s confluence with the mighty Columbia River barely 100 feet above sea level.

Yakima Sportsman State Park owes its preservation and its distinctive name to the generosity of a group of waterfowl hunting enthusiasts who purchased lands in the Yakima River floodplain in the 1940s.

Folds, Floods, Meanders and Mines

The park is situated in a geographic area called the Yakima Fold Belt, an area of central Washington where tectonic compression of the layered Columbia River Basalt lava flows results in a series of parallel ridges that run perpendicular to the force of the stress—kind of like kicking a rug creates ridges in the fabric.

Cape Disappointment State Park spreads over the land north of the point where the Columbia River and the Pacific Ocean meet. The park includes three headlands of basalt rock cliffs: Cape Disappointment overlooking the river, North Head above the strand of Long Beach, and McKenzie Head, midway between the other two headlands. The basalt bedrock of these wave-pounded cliffs are ancient lava flows that erupted on the ocean floor. Encountering the cold ocean water, the lava quickly hardened into bulbous masses geologists call pillow lava.

Beacon Rock State Park centers on the prominent rock monolith that rises more than 840 feet above the Columbia River, but the park’s landscapes and stories extend well beyond the rock.

Boring Volcanics and Ice Age Floods

Beacon Rock is the core of an extinct volcanic cinder cone that erupted about 57,000 years ago. It is part of a volcanic feature geologists call the Boring Volcanic Field (named for the town of Boring, OR), as is the explosive caldera featured in nearby Battle Ground Lake State Park.

A visitor to Old Ruby State Park Heritage Site is likely to find themselves alone among tall ponderosa pines gently swaying in the breeze. But if one could travel back in time to the late 1800s, there would have been a bustling town with a population of more than 1,000 on the site. Ruby City was one of the most consequential silver mining locations in the history of Washington, and its development generated intense excitement just as Washington became the 42nd state in the United States.

Flaming Geyser State Park straddles the Green River at the lower end of the Green River Gorge, a unique place where sandstone bedrock, covered by glacial deposits in most of the Puget Sound lowlands, is revealed by the downcutting of the river through the formation. Seams of coal interwoven with the sandstone fueled a mining industry in the local area. On October 4, 1911, coal miner Eugene Lawson drilled a test bore in today’s park area, attempting to locate a coal seam. At 390 feet deep, he found a seam 6.5 feet thick.

Lyons Ferry State Park occupies a place at the drowned confluence of the Palouse and Snake Rivers, where people have crossed over the rivers for millennia.

Ice Age Floods Carve a Canyon

The walls of the Snake and Palouse River Canyons, and the cliffs which soar over the park are made of basalt lava flows that erupted from vents in southeast Washington. The forces of plate tectonics continue to shape this landscape, wrenching and stressing the vast layered basalt flows that make up Washington’s Columbia Plateau, weakening the rock along subtle fractures.

The story of Mount Pilchuck State Park goes deep. The distinctive blocks of light-colored quartz monzonite (a rock like granite but with a smaller proportion of quartz crystals) that a hiker must scramble over to reach the historic fire lookout were once molten magma slowly cooling thousands of feet below the earth’s surface. The mechanisms of plate tectonic subduction elevated the rocks to 5,324 feet above sea level to put Mount Pilchuck’s prominent alpine summit barely 18 miles from salt water at the Snohomish River estuary.

Bottle Beach State Park’s sweeping shoreline provides a window into one of the most important shorebird feeding area on the Pacific Coast. Grays Harbor attracts more than a million birds each spring and up to 20 percent of these migrating birds use the area just off Bottle Beach, peaking in late April and early May. Shorebirds are attracted to this spot because the mudflats just offshore host abundant shrimp-like Corophium amphipods for them to eat. The rich supply of amphipods, up to 55,000 per square meter, is unique along the Pacific Coast.

Doe Island Marine State Park preserves an entire island along the southeastern coastline of Orcas Island in the San Juan Archipelago. It takes its name from the prevalence of deer in the area—nearby place names include Doe Bay, Deer Point and Buck Bay.

A Rocky Island

The San Juan Islands are distinct from most of Puget Sound in that they feature shorelines with exposures of hard bedrock, rather than the bluffs of clay, sand and gravel left by Ice Age glaciers that are predominant on most of Washington’s Salish Sea, the state’s inland saltwater passages.

Sequim Bay State Park hugs the western shore of Sequim Bay, which takes its name from an Indigenous village located near its mouth. The bay is protected at its entrance by two spits that have developed over centuries atop a flat section of underwater land. The spits, which nearly enclose the bay, are made up of glacial debris from the last Ice Age—mostly sand and gravel—that eroded into the water from nearby bluffs and was carried by ocean currents. An 800-foot gap between the spits leads into the seven-mile-long bay.
