Captain Clark & his men building a line of Huts.

The second edition of Patrick Gass's A Journal of the Voyages and Travels of a Corps of Discovery, Under the Command of Capt. Lewis and Capt. Clarke of the Army of the United States, From the Mouth of the River Missouri Through the Interior Parts of North America to the Pacific Ocean, During the Years 1804, 1805 and 1806 (1810) includes six engraved scenes from the Lewis and Clark Expedition, including this depiction of activity that took place in November 1804. The men are portrayed building a winter encampment near the Mandan Indian villages in present-day North Dakota.

Gass served as a sergeant in the expedition and kept a personal journal during their travels. This edition of his journal was printed by Mathew Carey of Philadelphia. The first edition of Gass's work, published in 1807, did not include any illustrations. Gass may have created the drawings himself, or he may have consulted with another artist. Gass's journal was the first such account published about the expedition; in it, he coined the term "Corps of Discovery."
