Heights of Mountains, Lengths of Rivers

For over 100 years, atlas and map publishers in the United States and Europe published a style of map that was a visualization of the heights and lengths of the world’s mountains and rivers.  Some of the earliest examples appeared in Europe towards the end of the 18th century.  In the United States, the form was popular throughout the 19th century and the early part of the 20th.  These maps appeared in atlases, as wall maps, and as pocket maps.  One of the most elegant examples was engraved originally on copper by map publisher Henry Tanner in Philadelphia in 1836 and then continued by S.
