William Clark, November 3, 1805: "... Passed a Small Prarie on the Stard. Side above, a large Creek opposit qk Sand River on the Stard. Side, extensive bottoms and low hilley Countrey on each Side (good wintering Place) ..."

Cottonwood Beach was one of the sites voted on for the winter camp, but lost out to Fort Clatsop. On the return trip, the Corps of Discovery camped here for six days from March 31 through April 6, 1806 while they gathered provisions and Clark led a group of men back down the Columbia to explore the Willamette River.

Lewis & Clark historian and Washougal resident Roger Daniels was instrumental in the development of Captain Clark Park, which was dedicated during the Bicentennial. Roger will lead a tour of Cottonwood Beach and share his experiences and insights on the creation of the park.

Point William Interpretive Panel and Keith G. Hay Bench Dedication

Astoria Riverwalk at Alderbrook Lagoon

A little-known Lewis & Clark campsite is about to get some well-deserved recognition. On Saturday, November 7, the Oregon Chapter-Lewis & Clark Trail Heritage Foundation will dedicate an interpretive panel highlighting the Corps of Discovery’s 10-day stay at Point William (Tongue Point) and a bench honoring Keith G. Hay, long-time chapter leader. Join us at 2:00 p.m. for a celebration at the Alderbrook Lagoon at the eastern-most point of the Astoria Riverwalk.

On November 27, 1805 following their stays on the north shore of the Columbia River, the Corps of Discovery headed to the south shore to prepare for winter. Captain William Clark wrote:

“…we proceeded on between maney Small Islands passing a Small river of ____ yds wide which the Indians Call ___ and around a very remarkable point which projects about 1½ Miles directly towards the Shallow bay the isthmus which joins it to the main land is not exceding 50 yards and about 4 Miles around. We call this Point William”

Funding for this project was provided by the Lewis & Clark Trail Heritage Foundation from the Lewis & Clark Trail Stewardship Endowment, a National Council of the Lewis & Clark Expedition Bicentennial Legacy Project; the Oregon Chapter-Lewis & Clark Trail Heritage Foundation; and friends and family of Keith Hay. Thanks to our partners for their assistance: Astoria Parks and Recreation, Tongue Point Job Corps, the Clatsop-Nehalem Tribe, the Astoria Chamber of Commerce and the National Park Service.

Keith G. Hay

A career professional in outdoor recreation and environmental management, Keith Hay co-authored a landmark study commissioned in 1962 by the Interior Department’s Bureau of Outdoor Recreation to define what later became the National Lewis & Clark Historic Trail. In those years of data-gathering along the Trail, he studied the rivers and land route in detail across 10 states. Years later he was instrumental in resurrecting the Oregon LCTHF Chapter, becoming its president. He was also deeply involved in planning the Lewis and Clark Bicentennial in Oregon as the vice president of LCBO’s board.

Keith’s book The Lewis and Clark Columbia River Water Trail, a Guide for Paddlers, Hikers, and Other Explorers was published before the Bicentennial. It was immediately sought after by canoeists and kayakers as well as those driving along both sides of the river from Bonneville Dam to the river’s mouth, pointing out not only historic places but safe passages and overnight camping spots. The Lewis & Clark Trail Heritage Foundation honored Keith with its Meritorious Achievement Award at the 2011 Annual Meeting. Keith died in 2013.

Auto Tour to Pomp's Gravesite

On Saturday, June 6 the Idaho Chapter will host an auto caravan to Jordan Valley, OR to visit the grave of Sacagawea and Charbonneau's son, Jean Baptiste, better known to us as baby Pomp. After traveling with the Corps of Discovery, Jean Baptiste went on to have an adventurous life of his own, and died while traveling from California to the Idaho/Montana gold fields. We will visit his gravesite, the abandoned stage stop nearby, and learn more of the local history at the Heritage Museum in Jordan Valley.

One note, they really need to KNOW who is coming, so if this is something you'd like to hitch up with, PLEASE contact Sue by June 4 at the latest. Thanks!
