On July 25, 1806, Captain Clark inscribed his own 

name and date in the rock of "Pompeys Tower," 

named for Sacagawea's son whom he nicknamed 

"Pomp." Today, Pompeys Pillar National Monument, 

near Billings, Montana, is the only site along the 

entire Lewis and Clark National Historic Trail where 

the public can view physical evidence of the Lewis 

and Clark Expedition.

Tribal Reservations are not public lands and are enclosed by boundaries established by treaties and proclamations. In most 

cases these boundaries enclose more acreage than is held in trust. It is impractical to separate trust lands from other 

interspersed lands at this scale. Tribal Reservations smaller than a township (36 square miles, or roughly 23,000 acres) 

generally are omitted. Scale does not permit naming each of the Indian lands in California.

Homecoming

With the Missouri River's

current, the Corps of Discovery

covered up to 70 miles a day

and returned to St. Louis on

September 23, 1806. The

expedition had traveled nearly

8,000 miles of territory in

over 2 years. Their detailed

journals contributed important information about the

land, its geographic features,

its natural resources, and its

native peoples.

Indian Country

The Corps of Discovery

encountered the diversity and

generosity of many Indian

Nations as they traveled across

the land and waters. The expedition survived and succeeded

because of the shelter, supplies,

good will, and cooperation of

Native American people they

met. Now, as then, the people,

cultures, and land have much

to share.

Exploration

The Corps of Discovery traveled

up the Missouri River, over the

Rocky Mountains, and down the

Snake and Columbia Rivers.

Despite great physical challenges,

isolation, and near starvation at

times, the expedition mapped

vast territories of the West. In

November 1805, they reached

their ultimate destination, the

Pacific Ocean. The words of

their journals provide exciting

glimpses of their remarkable

adventures.

Recruitment

Journeying down the Ohio

River, Lewis, and co-commander

Captain William Clark,

recruited civilians and military

personnel of "hardy stock" from

along the Ohio and Mississippi

Rivers. The members of the

expedition were as diverse in

backgrounds as the lands they

were to explore. Each member

provided critical skills and

expertise for the success of the

mission.

Preparation

On January 18, 1803,

President Jefferson asked

Congress for $2,500 for a

small U.S. Army unit to

explore the Missouri and

Columbia Rivers. Jefferson

chose Captain Meriwether

Lewis to lead this expedition.

To prepare for this monumental trek, Lewis studied a

wide range of scientific topics

in Philadelphia. Lewis also

assembled supplies and

armaments from Harpers

Ferry and recruited

boatmen from

Pittsburgh.
