MT. UNAPPROACHABLE : AUSTRALIA

Mt. Unapproachable, at an elevation of 505 m (1657 ft), is an isolated mountain on the northern side of Lake Neale.

Named by the explorer Ernest Giles during his 1872 expedition west of Alice Springs, who sighted and named Lake Amadeus and spotted a mountain to the west.

He was unable to approach it, as his path appeared to be blocked by the lake as he continued west along its northern shoreline. In fact he over-estimated the size of Lake Amadeus and missed the bridge of land between Lake Amadeus and Lake Neale (pictured with Mt. Unapproachable top center). This was a significant oversight for Giles' expedition, who could see both the as yet undiscovered Ayers Rock and Kata Tjuta directly South, but could not reach them as the dry lake bed was not able to support the weight of his horses. The next year, William Gosse climbed and named both rises.

It was not until 1930, when Franke Neale conducted an aerial expedition of the desert regions NW of Alice Springs that the lake got its name. Part of a chain of salt lakes that stretches about 500 km (310 mi), from Lake Hopkins in the west to the Finke River in the east.

The lake is usually a dry salt plain, and only holds water for short periods after heavy rainfall. This drainage basin is known as the Amadeus Basin.

This is the 3rd post in a series using a selection of images taken during one pass over the continent.

The overlay photograph was taken 12 seconds after the image highlighted in my last post, during which time the @iss traveled* 86 km (54 miles) (*Between Nadir Points : distance over ground) on a SW-NE pass.

This image location is 115 km (72 miles) NE of the prior post in the series.
