This 370 megapixel poster shows the location of 22 camps of the Lewis and Clark expedition featured in the series of posters from the USGS showing hi-res images of the area around each camp as it appeared nearly 200 years later. The naturalistic map shows the West as Lewis and Clark and the Corps of Discovery saw it--devoid of cities, political boundaries, or other markings. Only the path they followed is marked in red.
Recommended print size: 36x24 inches to fit a standard poster frame, but will look good at 78x52 inches.
Before buying, look for the “Customize it!” button on the lower right below “Add to cart,” then “Print Options” mid-upper left. Enter one of the dimensions for the desired frame size.
