(GISuser.com Feature) On May 14, 1804, Capt. Meriwether Lewis and Lt. William Clark, charged by President Thomas Jefferson with finding a route to the Pacific Ocean, embarked from Camp Dubois, Ill., on the east bank of the Mississippi River, upstream from St. Louis. Read on for some interesting related facts and figures from the US Census Bureau.
They were accompanied by a 33-member group skilled in botany, zoology and outdoor survival. The Corps of Discovery arrived at Oregons Pacific coast in November of 1805 and returned to St. Louis on Sept. 23, 1806.
To commemorate the Lewis and Clark expedition, as well as the Louisiana Purchase, the U.S. Mint over the next two years will produce four versions of a redesigned Jefferson nickel. The new designs will replace Jeffersons home, Monticello, on the coins reverse side. The first version, shipped to commercial banks earlier this month, features a design similar to the original Jefferson Peace Medal commissioned for the Lewis and Clark expedition. Lewis and Clark handed out these medals as tokens of goodwill to American Indians they met along their route. Later this year, a second Jefferson nickel will be issued, depicting the boat Lewis and Clark used on their expedition.
