Photographer's Note

Sorry, nothing new today. Reposting this photo because the image quality in the original was such crap, now it looks more like the print version. Neatimage filtrered, darkened sky, contrasted and added green. I deleted the old posting and will post it to WS (not sure if this is the proper way to repost images). About lake Tahoe:

The Lake Tahoe Basin was formed by geologic block (normal) faulting about 2 to 3 million years ago. A geologic block fault is a fracture in the Earth's crust causing blocks of land to move up or down. Uplifted blocks created the Carson Range on the east and the Sierra Nevada on the west. Down-dropped blocks created the Lake Tahoe Basin in between. Some of the highest peaks of the Lake Tahoe Basin that formed during this process were Freel Peak at 10,891 ft (3,320 m), Monument Peak at 10,067 ft (3,068 m) (the present Heavenly Valley Ski Area), Pyramid Peak at 9,983 ft (3,043 m) (in the Desolation Wilderness), and Mt. Tallac at 9,735 ft (2,967 m).

Snow, rain, and streams filled the southern and lowest part of the basin, forming the ancestral Lake Tahoe. Modern Lake Tahoe was shaped and landscaped by the scouring glaciers during the Ice Age (the Great Ice Age began a million or more years ago). Many streams flow into Lake Tahoe, but the lake is drained only by the Truckee River, which flows northeast through Reno and into Pyramid Lake in Nevada.

Lake Tahoe is the second deepest lake in the United States and the tenth deepest in the world, with a maximum depth measured at 1,645 ft (501 m), average depth of 1,000 ft (305 m).

Lake Tahoe is about 22 mi (35 km) long and l2 mi (19 km) wide and has 72 mi (116 km) of shoreline and a surface area of 191 mi2 (495 km2). The floor of the Lake Tahoe Basin is at an elevation of about 4,580 ft (1,396 m), which is lower than the surface of the Carson Valley to the east! With an average surface elevation of 6,225 ft (1,897 m) above sea level, Lake Tahoe is the highest lake of its size in the United States.

The water in Lake Tahoe could cover a flat area the size of California 14 in (36 cm) deep. This amount of water is enough to supply everyone in the United States with 50 gallons of water per day for 5 years. The amount of water that evaporates from the surface of Lake Tahoe every year could supply a city the size of Los Angeles for 5 years.

The water temperature near the surface generally cools to 40 to 50oF (4.5 to 10oC) during February and March and warms to 65 to 70oF (18 to 21oC) during August and September. Below a depth of 600 to 700 ft (183 to 213 m), the water temperature remains a constant 39oF (4.0oC).
