Lewis and Clark and the U.S. Geological Survey in North Dakota
Introduction
President Thomas Jefferson instructed Meriwether Lewis, "Beginning at the mouth of the Missouri, you will take
observations of latitude & longitude, at all remarkable points on the river, & especially at the mouths of rivers…."
(DeVoto, 1953). Thus, the
journals of Lewis and Clark detail the confluence of the Missouri River with its tributaries.
The Cannonball, Little Missouri, and Yellowstone Rivers,
which flow through North Dakota, are notable entries in the
journals.
In addition to the confluences of the Missouri River and its tributaries,
this site focuses on the Fort Mandan area, where Lewis and Clark spent the winter
of 1804–1805; the Bismarck/Mandan area,
from both historical and present–day perspectives; and the dams
that have greatly affected the present-day Missouri River.
