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'scurrent, the Corps of Discoverycovered up to 70 miles a dayand returned to St. Louis onSeptember 23, 1806. Theexpedition had traveled nearly8,000 miles of territory inover 2 years. Their detailedjournals contributed impor-tant information about theland, its geographic features,its natural resources, and itsnative peoples.

Indian Country

The Corps of Discoveryencountered the diversity andgenerosity of many IndianNations as they traveled acrossthe land and waters. The expe-dition survived and succeededbecause of the shelter, supplies,good will, and cooperation ofNative American people theymet. Now, as then, the people,cultures, and land have muchto share.

Exploration

The Corps of Discovery traveledup the Missouri River, over theRocky Mountains, and down theSnake and Columbia Rivers.Despite great physical challenges,isolation, and near starvation attimes, the expedition mappedvast territories of the West. InNovember 1805, they reachedtheir ultimate destination, thePacific Ocean. The words oftheir journals provide excitingglimpses of their remarkableadventures.

Recruitment

Journeying down the OhioRiver, Lewis, and co-commanderCaptain William Clark,recruited civilians and militarypersonnel of "hardy stock" fromalong the Ohio and MississippiRivers. The members of theexpedition were as diverse inbackgrounds as the lands theywere to explore. Each memberprovided critical skills andexpertise for the success of themission.

Preparation

On January 18, 1803,President Jefferson askedCongress for $2,500 for asmall U.S. Army unit toexplore the Missouri andColumbia Rivers. Jeffersonchose Captain MeriwetherLewis to lead this expedition.To prepare for this monu-mental trek, Lewis studied awide range of scientific topicsin Philadelphia. Lewis alsoassembled supplies andarmaments from Harpers

Ferry and recruitedboatmen from

Pittsburgh.
