Eugene Duflot de Mofras sailed to the Bering Strait and back, then provided a large map of the West Coast. He charted the major ports from San Blas to the Aleutians, including the mouth of the Columbia River and Nootka Sound.

A collection of Mofras' writings was edited by Marguerite Eyer Wilbur and published in 1937 as Duflot De Mofras' Travels on the Pacific Coast. The book contains descriptive accounts of the Oregon territory, Vancouver Island, the Fraser River and several HBC forts.
