Angola and Zambia – June 26th, 2012

Smoke spreads from Zambia (upper right) into Angola (upper left) and Botwana (lower right). Namibia (lower left), remains unaffected. Although the thumbnail image shows a cloud of smoke, upon opening the full image multiple blazes can be pinpointed in Zambia and near the Caprivi Strip, or “Four Corners” region where Botswana, Namibia, Zimbabwe and Zambia near form a quadruple frontier. Also of note in the image is the Okavango Delta (lower right quadrant) and the salty white surfaces of the Etosha (left) and Makgadikgadi (right) Pans.

The Four Corners is a region of the United States consisting of southwest Colorado, northwest New Mexico, northeast Arizona and southeast Utah. The boundaries of the four states listed above meet at one point, just left of the center of this image. It is the only such geographic point in the entire United States.

The Four Corners is part of a high Colorado Plateau. This makes the area a center for weather systems, which stabilize on the plateau then proceed eastward toward the central and mountain states. This weather system creates snow and rain fall over the central United States.

Mountain Ranges in the Four Corners include Sleeping Ute Mountains, Abajo Mountains and the Chuska Mountains. Protected areas in the Four Corners area include Canyon de Chelly National Monument, Hovenweep National Monument, Mesa Verde National Park and Monument Valley.

Also visible at the center left is the Glen Canyon National Recreation Area, encompassing the area around Lake Powell and lower Cataract Canyon in Utah and Arizona. This national recreation area covers 1,254,429 acres (5,076 km²).

The sands of the Kalahari Desert in Botswana appear green where the Okavango River pours onto them, creating the Okavango Delta. The other green area at the top is swampland in Africa’s “Four Corners” region.

The delta is fed from Angola’s October to April rainy season, although the waters generally don’t reach Botswana until December and don’t travel to the bottom end of the delta until July. As this image was taken in early October, at the start of Angola’s rainy season, the delta has not yet expanded to its maximum area.

Numerous important bodies of water and wetlands areas are visible in this fine, cloud-free image of Botswana, Angola, Zimbabwe, Zambia and the Caprivi Strip zone of Namibia.

In Botswana, which occupies the lower portion of the image, the Okavango River and Delta can be seen on the left, and the Makgadikgadi Salt Pans to the right.

Above the Okavango Delta is the Cuando River, which leads to a place known as Africa’s “Four Corners”, as Namibia, Botswana, Angola and Zambia share a quadruple frontier near the triangular swampy area visible northeast of the delta.

The upper portion of the image contains the Zambezi River and Barotse Floodplain in Zambia in the top left quadrant and Lake Kariba, on the border between Zambia and Zimbabwe, in the top right quadrant.

The Caprivi Strip and Africa’s “Four Corners”

Africa's "Four Corners" - June 21st, 2009

Africa's "Four Corners" - June 21st, 2009

The Caprivi Strip cuts horizontally in from the left and across the central band of this image,  ending to the right of the center. It is bordered by the Okavango, Cuando, Chobe and Zambezi rivers. The area is rich in wildlife and has mineral resources.

The strip is a narrow protrusion of Namibia eastwards about 450 km (280 miles), between Botswana on the south, Angola and Zambia to the north, and Okavango Region to the west.

As such, the area has been nicknamed Africa’s “Four Corners”. The site of this quadruple frontier is by the swamp located slightly northeast of the center.
