The Lewis and Clark Expedition (1803–1806), headed by Meriwether Lewis and William Clark, was the first American overland expedition to the Pacific coast and back. These two Google Maps mashups let you follow the trail from the comfort of your own home.

Starting in Pittsburgh this Google Map takes you on a stage by stage journey westwards across America, following the trail blazed by Lewis and Clark. The mashup uses excerpts from the diary of Meriwether Lewis to help evoke the historical journey.
