CRATER LAKE, USA
August, 2019
 
Crater Lake is a crater lake in south-central Oregon in the western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot-deep (655 m) caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of 1,949 feet (594 m),[4] the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth.
 
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.
