During the winter of 1805-1806 the Corps of Discovery built Fort Clatsop, in the Oregon Country near the mouth of the Columbia River. This encampment provided shelter for all 33 members of the Corps of Discovery as well as Captain Meriwether Lewis' Newfoundland dog, Seaman. According to the explorers' journals, Seaman served as a watchdog, hunter, retriever, companion and diplomat during the two-and-a-half year voyage of discovery.

In honor of this 34th member, Lewis and Clark National Historical Park will celebrate the 25th Annual Seaman's Day on July 11, 2018 at Fort Clatsop in Astoria, Oregon. The park has invited some guest Newfoundland dogs and their people to volunteer this day. This special event offers visitors an opportunity to learn about Seaman and to meet some modern Newfoundland dogs. Kids Corps dog-themed crafts will be available from 10am-3pm in the visitor center. Costumed rangers will be at the fort during the day to answer questions and share living history.
