Snow and Lakes in Southwestern USA

USA and Mexico – January 17th, 2013

Snow covers mountain ranges in southwestern USA, including the Sierra Nevada Mountains, which border the San Joaquin Valley, in southern California (upper left quadrant). The snow contrasts with the more arid land between ranges and in Mexico (lower half of image). Visible in the snow-free areas are bodies of waters such as the three-pronged Lake Mead (above center), in Arizona and Nevada, Lake Powell, surrounded by snow near the top edge, in Arizona and Utah, and the Salton Sea, in California near the Mexican border and northwest of the Gulf of California.

This image stretches from the southern half of the California Central Valley, USA, in the upper left quadrant, to El Vizcaíno Biosphere Reserve, in Baja California, Mexico, in the lower right quadrant. In between the two, the Colorado River spills tan sediments around Montague Island into the Sea of Cortes, also known as the Gulf of California.

Several mountain ranges can also be observed, including the Sierra Nevada Range, which bounds the California Central Valley to the east, the Tehachapi Mountains, south of the valley.

East of the Sierra Nevada ranges lies the large desert of the Intermontane Plateaus a large, arid desert. The southern portion of this region, known as the Great Basin, contains salt flats, drainage basins, and many smaller mountain ranges running north to south.

The California Central Valley, bounded by the Coastal Mountain Ranges in the west, the Sierra Nevada to the east, the Cascade Range in the north and the Tehachapi Mountains in the south, is California’s agricultural heartland and grows approximately one-third of the USA’s food.

East of the Cascades and Sierra Nevada ranges lies the Intermontane Plateaus (also known as the Intermountain West), a large, arid desert. The large southern portion, known as the Great Basin, consists of salt flats, drainage basins, and many small north-south mountain ranges. The Southwest is predominantly a low-lying desert region, which continues into Baja California and the rest of northern Mexico.

This FAPAR image highlights the great contrast between the high vegetation index of the California Central Valley and surrounding mountains, and the low photosynthetic activity of the desert areas.

Sacramento and the Sierra Nevada Mountains, California USA – September 5th, 2009

Sacramento is the capital of the state of California in the USA. The city is located along the Sacramento River and just south of the American River’s confluence in California’s expansive Central Valley.

To the east of the Central Valley is the Sierra Nevada mountain range. The change in elevation from 25 feet (8 meters) above mean sea level in the valley around Sacramento to around 6000 feet (about 1830 meters) at the right edge can be observed in this orthorectified image.

The cities of Oakdale, Stockton, Manteca, Modesto and Turlock (from top to bottom) appear bright white and light grey, distinguishing themselves from the mostly dark grey of the rest of California’s Central Valley in this  orthorectified image.

To the east of Oakdale is the Camanche Reservoir, located in the foothills of the Sierra Nevada. It is fed by the Mokelumne River, which originates in the higher altitudes of the mountain range.

Part of the Sierra Nevada range itself becomes visible at the far right after moving past the foothills. On the far left, in the lower corner, a small section of the Diablo Range (part of the Coast Ranges) can also be noted.
