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.

The landscape north of the Great Salt Lake (lower right) in this  orthorectified image of Utah, USA, includes several mountain ranges, while the Great Salt Lake Desert can be seen to the west.

The small ridge in the upper left quadrant is known as the Raft River Mountains. This range includes George Peak, a mountain summit that climbs to 9,567 feet (2,916.02 meters) above sea level.

The larger range running north-south on the right side of the image is the Promontory Mountains. This range reaches down into the lake, creating a 20mi long peninsula.

Running through Promontory Point at the tip of this peninsula is a railroad on a causeway called the Lucin Cutoff, identifiable here as a straight white line cutting across the lake and desert.

Two significant mountain ridges can be observed in this  orthorectified image of the Great Salt Lake (right) and Desert (left) in the state of Utah, USA.

The ridge rising up above the flat salt desert in the lower left corner is called the Newfoundland Mountains. Their highest summit is the rugged Desert Peak at 6800 feet, ascending about 2800 feet from the surrounding salt flats.

Moving across to the other side of the lake, the Promontory Mountains run north-south and jut out into the water, forming a twenty mile long peninsula whose southernmost tip is called Promontory Point.

Major peaks of the Promontory range are Messix Peak at 7,349 feet (2,239.98 m), Mt. Tarpey at 6,965 feet (2,122.93 meters), and Lead Mountain at 5,781 feet (1,762.05 meters).

The Promontories have historical significance because the First Transcontinental Railroad was completed just north of the range, at Promontory, Utah. Today, trains pass Promontory Point via the Lucin Cutoff, a railroad trestle that crosses the lake, visible here as a white line across the black lake waters.

The Sacramento Valley stretches between the Coastal Mountains (left) and the Cascade Mountains (right) in California, USA.

Here, the Coastal Mountains include the peak known as Pence Mountain, a summit in Colusa County that climbs to 1,857 feet (566.01 meters) above sea level.

The Cascades, on the other hand, include a peak called Promontory Point, a summit in Tehama County that reaches  3,589 feet (1,093.93 meters) above sea level.

A small, seemingly out-of-place peak can also be seen in the middle of the valley, at the bottom of this  orthorectified image. These are the Twin Peaks, comprised of North Butte and South Butte, part of the Sutter Buttes.
