Zebulon Pike Explores the West
• Set out from St. Louis in 1805.
• explored the upper Mississippi
River, the Arkansas River and parts of
Colorado & New Mexico.
• In 1806, he viewed a mountain peak
rising above the Colorado plains. This
is known as Pikes Peak- at 14,115 feet,
one of the highest elevations in the
lower 48 states.
• the journeys of Lewis & Clark as well
as Zeb Pike excited Americans and
the information that each obtained
while investigating Jefferson's
"purchase" would prove valuable to the
young nation as it would expand
further to the west.
