Route map. It would be almost the same distance to go around both Marrowstone and Indian Islands together as just Marrowstone Island by itself.
No matter which way I turned, the wind seemed always to be blowing in my face. When I was heading southeast from the launch point toward the southern tip of Marrowstone Island, the wind was in my face. When I reached Kinney Point and turned northeast, the wind somehow continued to blow in my face, notwithstanding the 90-degree turn I had just completed. When I headed north up along the eastern side of the island, the wind, unbelievably, continued to blow directly in my face. When I finally turned northwest at Marrowstone Point at the northern end of the island, the wind once again continued to blow in my face, even though I had now turned 180 degrees from my original heading.
The nearest weather stations, at Smith Island and Port Townsend, reported wind from the southwest—just about the only point of the compass from which I did not face any wind. Topographic features must somehow have caused the local wind to revolve clockwise around Marrowstone Island, which would generate a continuous headwind during a counterclockwise navigation.

Kayaking over eelgrass bed, Oak Bay, Marrowstone Island. The healthy eelgrass beds help make the west side of Marrowstone Island one of Washington State’s principal spawning grounds for Pacific herring,
Doorway to beachfront stairs, Marrowstone Island. Most of the shoreline is high bluff, so “waterfront” homeowners must resort to ever more outlandish schemes to reach the beach.

Wind was not the only dynamical force refusing to behave as expected. Tidal currents also proved troublesome. My plan was to catch the tail end of the morning ebb, which generally sets northward up Admiralty Inlet along the eastern side of Marrowstone Island, but that proved more complicated than expected.
Out in the main channel of Admiralty Inlet, I could see large, intimidating tideraces. It seemed best to avoid such chop. Hoping for an easier ride, I hugged the shoreline of the island, where the water was calmer.
The inshore water was calmer, but it was also flowing in the opposite direction from the main current. Instead of a helpful boost northward, a nearshore eddy began unhelpfully pushing me southward, reducing my speed to less than two knots. At this rate, it would take three hours to round the top of the island, by which time the favorable ebb would have ended and an unfavorable flood would have developed.
Perhaps the tideraces in the main channel didn’t look so bad after all, I thought. At least the tideraces were moving in the correct direction, unlike the inshore eddy. I headed a few hundred meters offshore into the channel and entered a morass of swirling, bumpy whitecaps.
Waves buffeted me from all directions. Whirlpools yanked my bow this direction and that. Spray from the whitecaps soaked my face, courtesy of that mysteriously ever-present headwind. It was all worth it, though, because my speed over ground leaped from a pathetic two knots to a heroic six and a half knots. A pod of harbor porpoises surfaced just an arm’s length from my cockpit, as if celebrating our ride together.
In no time, I drew level with the lighthouse at Marrowstone Point. Here, I deliberately exited the rocketing tideraces and re-entered the inshore eddy, lest I be carried past the tip of Marrowstone Island and off beyond the horizon of Admiralty Inlet.
View from Cascadia Marine Trail campsite at Fort Flagler. The kayakers’ campsite here is separated by hundreds of meters of forest from the crowded, sun-baked car-campground.
Mule deer, Fort Flagler. The mammal species I saw this trip were: mule deer, harbor seal, harbor porpoise, river otter, and a couple of fat, short-tailed rodents I suspect may have been mountain beavers.
Sunset from Fort Flagler beach. A cool breeze blew off Admiralty Inlet, providing welcome relief from the July sun.
Bird life on the water was unspectacular, as is generally the case on Washington’s inland waters during July. There were large numbers of pigeon guillemots and rhinoceros auklets but only a handful of marbled murrelets and not a single common murre. There were also no sea ducks, loons, or grebes, and almost no cormorants.
The situation ashore was more encouraging. There were large numbers of finches in the grassy areas, including American goldfinches, house finches, and red crossbills. The forests were full of nuthatches and chestnut-backed chickadees. I heard both western and olive-sided flycatchers, although I only ever saw any westerns. Of most interest to a birder in western Washington, there were a pair of house wrens in the kayakers’ campsite. This species is common in eastern Washington, but uncommon in most areas west of the Cascade Mountains. The only other place I have seen house wrens in western Washington is in the San Juan Islands, where they are locally common.
Marbled murrelets, Admiralty Inlet. This alcid species exhibits strong pair-bonding behavior on the water.
Pigeon guillemot, Admirality Inlet. The bright red feet always come as a surprise.
Song sparrow on the beach at Fort Flagler. Besides this sparrow species, I also saw white-crowned, golden-crowned, fox, house, and savannah sparrows, Oregon junco, and spotted towhee—the standard summertime sparrow smorgasbord in western Washington.
Red crossbills, Fort Flagler. The crossbills were drinking from the gutter of the fort’s old powerhouse.
Fort Flagler at the northern end of Marrowstone Island is a kayaker’s paradise. Kayakers at Fort Flagler enjoy the best campsite in the park, a secluded area right off the beach. While the car-campers were piled on top of one another in a shadeless parking lot, I was so far from the main campground that I could only hear the other campers when they honked the horns of their cars.
In the morning, I took a tour of Fort Flagler’s Endicott Period coastal artillery batteries. Fort Flagler was one vertex of the Triangle of Fire, a trio of forts sited on both sides of Admiralty Inlet during the late nineteenth century to protect the naval bases in Puget Sound. During its heyday between the Spanish-American War and World War I, Fort Flagler’s armament consisted of a main gun line with two ten-inch batteries and one twelve-inch battery, a double-sized battery of twelve-inch mortars, two secondary batteries of six-inch guns plus another of five-inch guns, and two batteries of rapid-fire three-inch guns to hit fast-moving minesweepers and torpedo boats. The entire twenty-six-piece arsenal was supported by a network of position-finding stations, fire-control rooms, shell-spotters’ posts, and searchlights, to say nothing of the armored, underground powder and shell magazines and hoists underlying the batteries themselves.
The big guns were dismantled between the world wars, when advances in naval gunnery and air-delivered weaponry rendered the Endicott Period forts obsolete. Today, all that remains of the once-formidable installation is a maze of concrete corridors, parapets, and magazines, moldering decade by decade into the earth like the temples of some lost civilization.
Inside base end station, Fort Flagler. This is not a firing position but an observation post from which spotters would shoot azimuths on approaching ships at fixed time intervals to enable the ships’ positions to be plotted.
Overgrown six-inch gun battery, Fort Flagler. Even from the landward side, the fortifications are difficult to spot from a distance. From the seaward side, the fortifications are all but invisible.
Entrance to six-inch gun magazine, Fort Flagler. The shells and powder were stored beneath many feet of concrete and earth, and not within line of sight of the entrances to the magazine.
Hoists and shot gallery for ten-inch gun battery, Fort Flagler. A well-trained gun crew could fire 617-pound (280 kg) shells at a rate faster than one shell per minute.
Stairs to ten-inch gun battery magazine, Fort Flagler. Each battery mounted between two and four guns, except the mortar battery, which mounted eight.
Marrowstone Island and its neighbor, Indian Island, are only barely separate islands. At low tide, two narrow, shallow channels lie between the islands at their northern and southern ends. Especially at the southern end, there can be less than a centimeter of water depth separating the islands at the lowest tide.
When the tide starts rising, water rushes through the gaps between the islands. The flow can be quite swift. For many decades, a pair of small culverts across the southern gap created a famously turbulent passage between the islands. Kayakers had to plan their trips around the culverts. Even with the water flowing in a favorable direction, the passage through the culverts could be intimidating for inexperienced paddlers.
In 2020, the culverts were replaced by a girder bridge. The bridge eased the passage between the islands not only to kayakers but also to fish. Today, the bay between the islands is a refuge for thousands of juvenile salmon.
Even with the new bridge, a kayaker still needs water before he can paddle anywhere. When I arrived at the southern end, the water depth was only a few millimeters. Impatient, I tried sliding my kayak up the channel, but the bottom was paved with rocks, barnacles, and razor-sharp oysters. Dragging a loaded boat across this bottom would have destroyed the boat. Portaging across half a mile (900 m) of muddy saltmarsh would have spared the boat but only at the cost of destroying me instead.
All I could do was wait for the water. It was already a hot day, and a saltmarsh is an unforgiving environment: shadeless, windless, and humid. Rather than bake on the mudflat for an hour, I hid in the shade under the bridge. Eventually, the water started rushing in from both ends. I hurried back to my boat, climbed aboard, and eased my way over the rapidly flooding oyster reefs.
Northern channel between Marrowstone and Indian Islands. Even in a kayak, I had to be careful not to run aground on the shoals.
Red rock crab, southern channel between Marrowstone and Indian Islands. There were so many crabs they could simply be scooped off the bottom by hand.
Ochre sea star in southern channel between Marrowstone and Indian Islands. This was the only sea star I spotted the entire trip.
Kayaking toward bridge connecting Marrowstone Island. Water rushed into the channel from opposite ends, meeting a few dozen meters north of the bridge.
In a tidy, weekend-sized package, Marrowstone Island delivered many of the best things about sea kayaking in Washington: fast currents and big waters, close encounters with wildlife, solitary camping, and archaeological relics. The island well deserves its reputation as a cornerstone of Washington kayaking.
