USA - October 3rd, 2011

This orthorectified image shows part of the Great Salt Lake, in Utah, USA. The lake itself appears dark grey, with bridges crossing it visible as long, light grey lines. The checkered area in the upper right quadrant is a series of man-made salt pans from which minerals are extracted.

Crossing the image from the top center to the middle are the Promontory Mountains, located on a promontory (peninsula) in the northern part of the Great Salt Lake. Promontory Point is at the southern tip of the range. Today, trains cross the point via the Lucin Cutoff railroad causeway across the lake, visible, as mentioned previously, as a think grey line.

Lake Nur Between Deserts in China

China - October 3rd, 2011

This image of China shows the eastern part of the Taklamakan Desert (light tan, left) and the Kuruktag Desert (darker and more orange tan, right). Located between the two is Lop Lake (Lop Nur), a group of small, now seasonal salt lake sand marshes.

The group of lakes appears as an indentation that is slightly darker in color than its surroundings. On the northern edge is a rectangular, teal green area, a Potassium chloride factory on salt pans in Lop Nur.

Salt Pans by Former Lake Lop Nur, China

China - February 13th, 2011

Situated between the Taklamakan and Kuruktag deserts, in the southeastern portion of Xinjiang Uygur Autonomous Region in the People’s Republic of China, are the now seasonal salt lake sand marshes of the former Lake Lop Nur.

The teal and green rectangular form in this area is a field of salt pans. While the desert in the basin by the salt evaporation pans and lake bed appears mostly flat, many high vertical rows of sand dunes can be observed to the south.

Salt Pans in Northern Part of Lake Eyre Basin, Australia – November 25th, 2010

Australia - November 9th, 2010

Lake Eyre, situated near the left edge of the image, is an ephemeral lake in central Australia. It is the lowest point in the country, in a basin at approximately 15 m (49 ft) (AHD) below sea level, and, on the rare occasions that it fills, it is the largest lake in Australia.

Typically a 1.5 m (5 ft) flood occurs every three years, a 4 m (13 ft) flood every decade, and a fill or near fill four times a century. The water in the lake soon evaporates with a minor and medium flood drying by the end of the following summer.

The Eyre Basin is a large endorheic system surrounding the lakebed, the lowest part of which is filled with the characteristic salt pan caused by the seasonal expansion and subsequent evaporation of the trapped waters. Even in the dry season there is usually some water remaining in Lake Eyre, normally collecting in a number of smaller sub-lakes on the playa.

Here, such white salt pans can be seen in the northern part of the basin. The eastern and western parts appear reddish and greenish in color, apparently still containing some water from the high summer rainfall in 2010.

Taklamakan Desert Dunes Near Khotan River – October 24th, 2010

China - October 13th, 2010

The Taklamakan Desert occupies the majority of this image, filling the greater part of the Tarim Basin in west-central China. The Kunlun Mountains are visible along the northern edge of the desert, capped in snow.

The greenish line cutting vertically across the desert is the Khotan River. Upon opening the full image, many individual rows of high sand dunes can be discerned throughout the desert, particularly to the east of the river.

On the right edge of the image thumbnail, just north of the desert, is Lake Bosten. Visible at the right edge of the full image, southeast of Lake Bosten, is the basin of the former Lake Lop Nur and a nearby field of salt pans, appearing as a greenish rectangular area. This part of the image appears hazy, as sand is blowing in the air.
