Lewis and Clark: A Legacy of Science - New Poster

A USGS poster commemorates the 200th anniversary of the Lewis and Clark Trek. The poster features two maps in parallel view:  above a beautiful reproduction of Lewis and Clark's Track Across the Western Portion of North America from the Mississippi River to the Pacific Ocean, published by Samuel Lewis in 1814; below is the same geographic area depicted with current remote sensing technology in a colorful image of the American landscape. The parallel map construction illustrates how difficult Lewis and Clark's expedition was, how well they mapped the terrain, and how far cartographic techniques have advanced in 200 years.



The map may be ordered by calling 1-888-ASK-USGS (1-888-275-8747).  The poster is item number 113605 and costs $10.00, plus a $5.00 handling fee per order.  Additional information about the poster is available at http://store.usgs.gov/historicmapsfromlca/index.html.
