MOUNT WHITNEY, CALIFORNIA, USA
September, 2019
 
Mount Whitney is the tallest mountain in the contiguous United States and the Sierra Nevada, with an elevation of 14,505 feet (4,421 m). It is located in East–Central California, on the boundary between California's Inyo and Tulare counties, 84.6 miles (136.2 km) west-northwest of the lowest point in North America at Badwater Basin in Death Valley National Park at 282 ft (86 m) below sea level.
 
In 2019 I thru-hiked every mile of the Pacific Crest Trail from North to South in 108 days. 
 
The Pacific Crest Trail (PCT), officially designated as the Pacific Crest National Scenic Trail, is a long-distance hiking and equestrian trail closely aligned with the highest portion of the Cascade and Sierra Nevada mountain ranges, which lie 100 to 150 miles (160 to 240 km) east of the U.S. Pacific coast. The trail's southern terminus is just south of Campo, California by the U.S. border with Mexico, and its northern terminus is on the Canada–US border on the edge of Manning Park in British Columbia; it passes through the states of California, Oregon, and Washington.
The Pacific Crest Trail is 2,653 mi (4,270 km) long and ranges in elevation from just above sea level at the Oregon–Washington border to 13,153 feet (4,009 m) at Forester Pass in the Sierra Nevada. The route passes through 25 national forests and 7 national parks. Its midpoint is near Chester, California (near Mt. Lassen), where the Sierra and Cascade mountain ranges meet.
