It's a long, four mile walk on a coarse gravel and cobble beach from Thompson Spit to Travis Spit at the northwestern tip of the Miller Peninsula. The spit extends westward about a mile across the mouth of Sequim Bay - most of the way across, at least.
While Travis itself is a fairly simple landform - a classic bay mouth spit - it's part of a complex of barrier beaches that make the story much more interesting. Together Travis and Gibson form paired spits, converging on the mouth of the bay. Gibson is also fairly large, extending south from Port Williams across Washington Harbor, and sheltering a large salt marsh. There's another smaller spit that extends north from the south shore of Washington Harbor. And Paradise Cove Spit is a north-directed spit that has formed just south of the base of Travis Spit on the eastern shore of Sequim Bay. Finally, if you look carefully, you'll see a small secondary spit on the southern side of the distal portion of Travis, with it's own narrow log-choked lagoon. You really need the aerial view and the map for this.
250 meters across the Sequim Bay channel is the site of the old Bugge Cannery (clams), which has been Battelle's Marine Science Laboratory for the last few decades. From the signs, I gather that Battelle may own much of high ground on Travis Spit. The central portion of Travis is narrow, but not so narrow as to show any obvious signs of overwash.
From the tip of Travis, it was a very long walk back to the State Park trail, a not so long walk up the trail to my bike, and then a refreshing ride back to my car. With a quick stop at the Discovery Bay store for chips, I made the 5:30 Kingston Ferry.
For those interested in visiting the Miller Peninsula or Travis Spit, a couple of thoughts. Miller Peninsula State Park is undeveloped, except for a new parking lot off of the Diamond Point Road and a network of trails largely maintained and signed by volunteers. Thompson Spit is best visited by hiking or biking in from the State Park parking lot. Travis would be best visited by parking at Panorama Vista County Park, which is reached off of the East Sequim Bay Road.
