The twenty-two individual images in the collection are satellite scenes that provide a modern view of historically significant stops along the expedition route - See http://edc.usgs.gov/LewisandClark/

See also signature Lewis and Clark events, dates, and descriptions at http://www.lewisandclark200.org/, or see the USGS Lewis and Clark Web site at http://www.usgs.gov/features/lewisandclark.html.

Of particular interest are the pointers to maps of the journey - some amazing graphics that show a variety of perspectives of the Trail. Also of interest, the Lewis & Clrk GNet - http://www.lewisandclarkgnet.org/ - interactive maps, video, journals etc... Lewis and Clark gNET is a collaboration between the University of Nebraska's Peter Kiewit Institute and the National Park Service Lewis and Clark National Historic Trail. Students, faculty and staff from The Peter Kiewit Institute are working in partnership with industry, tribal nations and agencies at the federal, state, and local level.
