Timeline
Departure from St. Louis
The expedition set out on a mid-July day in 1806, leaving the river town and moving onto trails that would take the party across grasslands and toward the Rocky Mountains. The date marked the practical beginning of the fieldwork and the moment supplies and personnel dispersed from the relative safety of settlement.
Location: St. Louis (territory near Mississippi River)
Contact with Plains Villages
Early in the overland phase the party encountered villages and camps on the plains where trade and cautious diplomacy took place; exchanges of goods and information followed, teaching the Americans how to move through a landscape dominated by indigenous trade networks.
Location: Central Great Plains
Sighting of the High Peak
From a ridge the leader's party sighted a solitary high mountain that dominated the horizon; the feature was sketched and recorded in field notebooks as a major landmark commanding the surrounding plains.
Location: Eastern flank of the Rocky Mountains (present-day Colorado)
Attempted High-Country Exploration
The party made concerted efforts to penetrate higher altitudes and to measure river sources, facing severe weather, thin air and treacherous slopes that slowed progress and tested the men and animals of the expedition.
Location: Rocky Mountain foothills
Arrest by Colonial Forces
On a bleak plain the expedition was seized by Spanish colonial troops, who treated the Americans as intruders and obliged them to surrender instruments and to accompany them for administrative examination and custodial transfer.
Location: High-country borderlands (near San Luis Valley region)
Escort to Regional Capital
Under guard, the party was marched to a regional administrative center where officials examined their maps and instruments; the Americans were lodged but kept under supervision while authorities assessed their purpose.
Location: Santa Fe (administrative center of the region)
Transfer to Northern Provincial City
After administrative review, the prisoners were moved to a larger provincial city where officials undertook further interviews and copied geographic information from the expedition's papers.
Location: Chihuahua region
Release and Return toward U.S. Lines
Following diplomatic and local administrative processes, the detained Americans were eventually released and escorted toward border regions from which they could return to U.S. territory; the journey home continued through summer weather.
Location: Northern New Spain (approach to the border)
Arrival Back in American Territory
The expedition's survivors reached established American settlements and turned over their journals and instruments to military authorities; their observations began to be incorporated into official reports.
Location: American frontier settlements (near Mississippi region)
Publication of Expedition Account
The leader's journals and compiled notes were edited and published, making the expedition's observations, maps and stories available to a wider American audience and to officials planning further expansion.
Location: United States
Peak Named by Later Surveyors
A later party that more fully surveyed the region attached the leader's name to the prominent mountain first sketched in the earlier expedition's journal; the name entered maps and public imagination.
Location: Eastern slope of the peak (present-day Colorado)
