The Contenental Divide at South Pass (Wyoming). Water on the east side of the divide flows toward the Atlantic Ocean and water on the west side flows toward the Pacific Ocean. The emigrants always looked carefully at which direction the water was flowing in the streams when they neared this area as evidence of when they actually crossed the Continental Divide. The "pass' is actually about 20 miles wide and not everyone crossed at exactly at the same place. Today, wagon wheel ruts (or tracks) are clearly visible as the trail winds west. They look similar to the unimproved road tracks that cars and trucks make when traveling overland, but these marks were actually made by the wagons. The ground is so dry and hard-packed that the tracks still remain clearly visible.
