The Pike Expedition (July 15, 1806 – July 1, 1807) was a military party sent out by President
Thomas Jefferson and authorized by the
United States government to explore the south and west of the recent
Louisiana Purchase.
[Berry, Trey; Pam Beasley; Jeanne Clements (eds.) (2006), ''The Forgotten Expedition, 1804–1805: The Louisiana Purchase Journals of Dunbar and Hunter'', Editors' Introduction, p. xi] Roughly contemporaneous with the
Lewis and Clark Expedition, it was led by
United States Army Lieutenant
Zebulon Pike, Jr. who was promoted to captain during the trip. It was the first official
American effort to explore the western

and the
Rocky Mountains in present-day
Colorado. Pike contacted several
Native American tribes during his travels and informed them that the US now claimed their territory. The expedition documented the United States' discovery of
Tava which was later renamed Pikes Peak in honor of Pike. After splitting up his men, Pike led the larger contingent to find the headwaters of the
Red River. A smaller group returned safely to the US Army fort in
St. Louis, Missouri before winter set in.
Pike's company made several errors and ended up in
Spanish territory in present-day Southern
Colorado, where the Americans built a fort to survive the winter. Captured by the
Spanish and taken into
Mexico in February, their travels through present-day
New Mexico, Mexico, and
Texas provided Pike with important data about Spanish military strength and civilian populations. Although he and most of his men were released because the nations were not at war, some of his soldiers were held in Mexican prisons for years, despite US objections. In 1810, Pike published an account of his expeditions, which was so popular that it was translated into

Zebulon Pike, then age 27, to lead an expedition to the western and southern areas of the Louisiana Purchase to map the terrain, contact the Native American peoples, and to find the headwaters of the Red River. Pike left

in southern
Nebraska. At the
Pawnee village on September 29, Pike met with the Pawnee tribal council. He announced the new claim of protectorship by the United States government over the territory. He instructed the Pawnee to remove a Spanish flag from their village and to fly the American flag instead.
The expeditionary force turned south and struck out across the prairie for the
Arkansas River. After reaching it on October 14, the party split in two. One group was led by Lieutenant James Biddle Wilkinson, son of the General. They traveled downstream along the length of the Arkansas to its mouth and back up the Mississippi, safely returning to St. Louis.
Pike led the other, larger group upstream, to the west, toward the headwaters of the Arkansas. Upon traversing the

, Pike wrote, "This vast plains of the western hemisphere may become in time as celebrated as the sandy deserts of Africa; for I saw in my route, in various places, tracts of many leagues where the wind had thrown up the sand in all the fanciful form of the ocean's rolling wave, and on which not a speck of vegetable matter existed." When
Stephen Long led an
expedition to the area in 1820, he labeled the area on his map as the "
Great American Desert."
Pike in Colorado

On November 15, Pike recorded the first sight of the distant mountain
Tava which he called "Grand Peak". It has since been called Pikes Peak in his honor. Pike tried to climb the peak, hoping to get a view of the surrounding area to record on maps, the summit. Pike's group ascended a lesser summit nearby—likely
Mount Rosa. With winter threatening, Pike pressed onward up the Arkansas, and on December 7 the party reached
Royal Gorge, a spectacular canyon on the Arkansas at the base of the Rocky Mountains.
Pike next intended to travel to the headwaters of the Red River and head downstream to the Mississippi and relative safety in the lowlands. But, the company had gotten confused in its bearings, and they made several blundering steps trying to find the river. They were not equipped for a mountain expedition, nor for hard winter weather. Heading north, the party found the South Fork of the
Platte River and, following it upstream, came to what they thought were the headwaters of the Red. Turning back downstream, they returned to the point at which they had left the Arkansas originally. They had executed a large loop, taking weeks of precious travel time.
Hungry, cold, and exhausted, the party headed south over the mountains. Several men were left behind as they dropped from fatigue, but Pike doggedly pressed on. By January 30, he and the ten men still with him came to the
Rio Grande

at a point near
Alamosa in present-day southern Colorado and then part of the Spanish empire. Pike mistook the Rio Grande for the Red River he had been seeking. Here, he
built a fort and attempted to collect the rest of his men, who were strewn across miles of mountains behind him.
Capture

On February 26, in the night Pike and his remaining men were captured at their fort by Spanish soldiers from nearby
Santa Fe. Arresting the party as spies, the Spanish collected the rest of his men who had been scattered in the mountains, and marched them all south. The Spanish took them through Santa Fe,
Albuquerque, and

locals, and Pike made careful notes of the military strength and civilian population.
Chihuahua's Governor Salcedo released Pike and most of his men, as they were military officers of a neighboring country, with whom Spain was not at war. He ordered the repatriation of Pike, but held some of the soldiers of his party in jail in Mexico for years. The Spanish military escorted Pike and some of his party back north, through
San Antonio, Texas, arriving at the border with
Louisiana at
Natchitoches on July 1, 1807.
The Spanish formally complained to the
United States Department of State about the military expedition in its territory, but the government maintained that the party had been one of exploration only. Pike's capture by the Spanish and travels through New Mexico, northern Mexico, and Texas, gave him more information about Spanish power than his expedition could have done.
