Lucin Cutoff Crossing Promontory Point of Great Salt Lake, USA – October 6th, 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.

This image shows the Great Salt Lake, located in the northern part of the U.S. state of Utah. Salt Lake City and its suburbs are located to the southeast and east of the lake, while the Bonneville Salt Flats lie to the west.

It is the largest salt water lake in the western hemisphere. In an average year the lake covers an area of around 1,700 square miles (4,400 km2), but the lake’s size fluctuates substantially due to its shallowness.

A railroad line — the Lucin Cutoff — runs across the lake, crossing the southern end of Promontory Peninsula. The mostly-solid causeway supporting the railway divides the lake into three portions: the northeast arm, northwest arm, and southern.

This causeway prevents the normal mixing of the waters of the lake due to the fact that there are only three 100-foot (30 m) breaches. This is why in this image the northern half of the lake appears much darker than the southern half.

Snow Around the Great Salt Lake, USA

While many areas of terrain near the Great Salt Lake (center right) often appear whitish as they are covered in salt flats, the bright white areas in this image are caused by snow over the states of Nevada (bottom left), Utah (bottom right), Idaho (upper right) and Oregon (upper left).

Here, the Great Salt Lake Desert, east of the lake, appears tan in comparison with the white snow. The lower half of the lake itself appears brighter green than its darker northern half due to a concrete causeway, the Lucin Cutoff, which runs horizontally across and restricts the flow of water.

Great Salt Lake and Wasatch Range, Utah, USA

One of Utah’s defining characteristics is the variety of its terrain.  Eastern Utah, in the lower right quadrant, is a high-elevation area covered mostly by plateaus and basins. Running down the northern center of the state is the Wasatch Range, which rises to heights of about 12,000 feet (3,650 m) above sea level. Portions of these mountains receive more than 500 inches (12.7 m) of snow each year.

The Great Salt Lake and Great Salt Lake Desert can be seen west of these mountains. The southern half of the lake appears greener than the northern half due to a causeway, the Lucin Cutoff, which greatly restricts the flow of water between the two sections.

The Wasatch Range Between the Great Salt and Bear Lakes, Utah, USA

The Wasatch Range fills the landscape between the Great Salt Lake (left) and Bear Lake. This mountain range stretches about 160 miles (260 km) from the Utah-Idaho border, south through central Utah in the western United States. It is generally considered the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region.

The northern extension of the Wasatch Range, the Bear River Mountains, extends just into Idaho, constituting all of the Wasatch Range in that state.

Bear Lake is located near that northern extension of the mountains. It is a natural freshwater lake on the Utah-Idaho border and the second largest natural freshwater lake in Utah.

Bear Lake has been called the “Caribbean of the Rockies” for its unique turquoise-blue color, the result of suspended limestone deposits in the water.

The waters of the Great Salt Lake also have interesting color properties, as the top half of the lake appears brown while the bottom half appears dark green. This is due to the Lucin Cutoff, a railroad line that runs across the lake on a mostly-solid causeway. As it has only three 100-foot (30 m) breaches, the mixing of the lake waters is restricted. This has caused the northwest arm, Gunnison Bay, to become much saltier than the rest of the lake.
