Beginning Tues., March 9 visitors to the Ronald Reagan Presidential Library and Museum can "join" Meriwether Lewis and William Clark on their 1804-06 expedition by visiting the "Lewis and Clark: A Discovery for All Ages" exhibit on display through Oct. 7 at the library, 40 Presidential Drive, Simi Valley.

The first exhibit in the library’s new 4,000-sq.-ft. temporary gallery inside the new 25,000-sq.-ft. Presidential Learning Center, "Lewis and Clark" affords patrons the chance to "travel back in time," to experience what it was like to be Lewis and Clark as they journeyed down the Missouri River in their keelboat, wintered at Fort Mandan (1804), met the Teton Sioux Indians and Sacagawea, passed the Great Falls of the Missouri, and finally wintered (1805) at Fort Clatsop before returning home.

The hands-on exhibit incorporates movie-set style replicas for visitors to explore including a 40-ft. replica of their keelboat, a Missouri River dock, the trade goods Lewis and Clark brought with them on their expedition, a full-scale Teton Sioux teepee and the gates at Fort Clatsop.

Also on view will be historical documents from the National Archives in Washington, D.C.

"Lewis and Clark is the perfect opening for the Presidential Learning Center exhibit gallery," said Duke Blackwood, executive director of the Ronald Reagan Presidential Library and Foundation. "It offers a unique and wonderful opportunity for people of all ages to relate to these adventures and what they accomplished 200 years ago. It is a wonderful way to communicate a vital part of American history to today’s generations."

Library hours are from 10 a.m. to 5 p.m. daily. Admission fees range from $2 to $7; free for children age 10 and under. For more information, call (800) 410-8354.
