Alt Text Map of the Lewis and Clark National Historic Trail that spans almost the entire United States. The trail connects Pittsburgh, Pennsylvania to the east with the Pacific Ocean to the west. Journeys and routes are color-coded, and scores of sites and territories are labeled across the country. Extended Description A red-encased line stretches the length of the trail. A few green-encased sections represent where Lewis and Clark took different routes as they returned east. This description will start at the east and work west, following the path the Lewis and Clark Expedition took to the Pacific Ocean before describing variances on the return trip. Across the Midwest The trail begins in Pittsburgh, where Point State Park, the Fort Pitt Museum, and Heinz History Center are listed. Following the Ohio River northwest and then back south, the trail crosses into Ohio. There it passes Historic Fort Steuben, the Campus Martius Museum, Ohio River Islands, National Wildlife Refuge, Cincinnati, and Big Bone Lick State Historic Site. The Ohio River continues southwest between Indiana and Kentucky, passing Louisville with the Historic Locust Grove and Frazier History Museum, Clarksville with Falls of the Ohio State Park, and John James Audubon State Park.

Four sites continue south on the coastline from here: Fort Clatsop, Salt Works, Ecola State Park, and Cannon Beach. Return Routes Three versions of the return routes are shown: a solid green line for “Lewis and Clark return journey, 1806 (route shown where different from outbound journey).” A green, wide-dashed line represents Lewis’s path and a narrowly dashed line represents Clark’s return journey where they split for short legs of the trip. The first place of departure is in Washington, where the pair traveled south of the original route from the modern state line to Clarkston. The next departure is shortly east where they traveled south from Canoe Camp to Long Camp and then back up to resume the trail at Weippe Prairie. At Travelers’ Rest State Park, Lewis’s return route headed north to pass Missoula, Lewis and Clark Pass, Square Butte, and Lewis and Clark National Historic Trail Interpretive Center with Giant Springs State Park and Sulphur Springs in Great Falls. From here Lewis traveled northwest to Camp Disappointment and then swung back down and around to pass near the Museum of the Plains Indian and Two Medicine Fight Site. He then traveled parallel to and south of the original route across Montana to the Missouri-Yellowstone Confluence Interpretive Center. Clark had turned south at Travelers’ Rest Park and wound east past Big Hole National Battlefield, Yellowstone Gateway Museum and Sacajawea Park in Livingston, Western Heritage Center and Yellowstone County Museum in Billings, and Pompeys Pillar National Monument before meeting up with Lewis in Missouri-Yellowstone Confluence Interpretive Center. They traveled back to Pittsburgh together from there. Around the Park Five cities and sites in the mid-Atlantic are labeled. These are Lancaster and Independence National Historical Park, the American Philosophical Society, and Academy of Natural Sciences in Philadelphia, Pennsylvania; Harpers Ferry National Historical Park in Harpers Ferry, West Virginia; Washington, DC; and Monticello in Charlottesville, Virginia. The Lewis and Clark National Historic Trail driving route is shown in dark yellow, mostly paralleling and following all legs of the trails, including where Lewis and Clark separated on the return journey. Legend The legend at the bottom of the map reads as follows: Red line for Lewis and Clark outbound Journey, 1803-1805, Green solid line for Lewis and Clark return journey, 1806 (route shown where different from outbound journey), Green, wide-dashed line for Lewis return journey, Green, narrow-dashed line for Clark return journey, Light brown, all-capital and italic letters for Historic Indian group location, Dark brown, all-capital letters for Present-day Indian tribe reservation location, Dark yellow line for Lewis and Clark National Historic Trail Driving Route, and Red dot for Trail point of interest. A note in dark brown text next to Present-day Indian tribe reservation location reads, “Some Indian Nations who lived along the Missouri River during the Lewis and Clark expedition were later relocated to Oklahoma. These include the Delaware, Kaw, Osage, Otoe-Missourita, Pawnee, Ponca, Potawatomi, and Shawnee. Black text at the end of the legend reads, “Present-day state names and boundaries shown for reference only.” A scale next to this measures distances of 50, 100, and 200 kilometers and 50, 100, and 200 miles.
