A plume of smoke from a wildfire burning in the wooded foothills of the Sierra Nevada, east of California’s Great Central Valley, can be seen just to the right of the center of this image. The smoke from the fire is blowing towards the south-southeast, trailing over the valley.

The Sierra Nevada and Climate Change Issues – March 23rd, 2013

USA – March 22nd, 2013

Population growth and climate change are among the most significant threats facing the Sierra Nevada, one of the fastest growing regions in California. The mountain range can be seen here, flanking California’s Great Central Valley. Sprawling development is increasing vehicle miles and greenhouse gas emissions, destroying rare habitat and agricultural lands, and straining natural resources upon which our communities depend. Climate change compounds these problems and contributes a new host of concerns for snowpack levels, water management and recreation, wildlife, and the frequency and severity of fires.

Bodies of Water on Both Sides of Great Central Valley, California, USA

USA – October 7th, 2012

Several bodies of water can be seen on both sides of the Great Central Valley in the state of California, USA. On the right side of the image are Lake Tahoe (center, right) and Pyramid Lake (above, right). Both lakes are connected by the Truckee River, which is the sole outlet of Lake Tahoe and drains part of the high Sierra Nevada, emptying into Pyramid Lake in the Great Basin. Its waters are an important source of irrigation along its valley and adjacent valleys.

In the lower left quadrant is the San Francisco Bay, a shallow, productive estuary through which water draining from approximately forty percent of California, flowing in the Sacramento and San Joaquin rivers from the Sierra Nevada mountains, enters the Pacific Ocean.

Specifically, both rivers flow into Suisun Bay, which flows through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. However, the entire group of interconnected bays is often referred to as “San Francisco Bay”.

Sierra Madre Mountain Ranges Parallel to Coast of Mexico

Mexico - April 14th, 2012

Mexico is crossed from north to south by two mountain ranges known as Sierra Madre Oriental and Sierra Madre Occidental, which are the extension of the Rocky Mountains from northern North America. Here, these two ranges can be seen parallel to the coastline. From east to west at the center, the country is crossed by the Trans-Mexican Volcanic Belt also known as the Sierra Nevada. A fourth mountain range, the Sierra Madre del Sur, runs from Michoacán to Oaxaca. As such, the majority of the Mexican central and northern territories are located at high altitudes.

USA - November 21st, 2011

California’s Central Valley is covered by a thick white veil of fog in this image of the western United States of America. This large, flat valley that dominates the central portion of the state stretches approximately 450 miles (720 km) from northwest to southeast, and covers an area of approximately 22,500 square miles (58,000 km2).

The valley is bordered to the east by the Sierra Nevada Mountains, which, true to their name, are capped in snow in this image. Beyond the mountains lies the the Great Basin of the western USA, which  includes valleys, basins, lakes, and mountain ranges of Basin and Range topography.
