Echo Summit, Mountain pass in Sierra Nevada, California, US

Echo Summit is a mountain pass in the Sierra Nevada of California, carrying U.S. Route 50 between Twin Bridges and Meyers at an elevation of about 7,400 feet (2,250 m). The road winds through the pass with open views of surrounding pine-covered ridges and rocky peaks.

The Lincoln Highway's Sierra Nevada Southern Route ran over nearby Johnson Pass in 1913, not over Echo Summit. The present alignment over Echo Summit was built between 1936 and 1939. The pass became a California Historical Landmark in 2014, the fifth sports-related site in the state.

Echo Summit hosted the 1968 U.S. men's Olympic track and field trials from September 6 to 16, a month before the Mexico City Games. A Tartan track, similar to the one in Mexico City, was installed in a ski area parking lot, with Ponderosa pines left in the infield. Four world records were set there. The site became a California Historical Landmark in 2014.

U.S. Route 50 crosses the pass at postmile 66.48 between Twin Bridges and Meyers, south of Lake Tahoe. The Pacific Crest National Scenic Trail can be joined at the summit trailhead. The old ski area southwest of the summit is now Adventure Mountain, a snow play area for sledding and tubing.

The Tartan track laid at Echo Summit in July 1968 was designed to be dismantled and reinstalled; the following summer it was moved to South Tahoe Middle School, where it survived until 2006. The high jump pit stood among huge boulders, and hundreds of Ponderosa pines remained in the infield, densest at the north end.
