The Newfoundland Mountains (left center) in Utah, USA, rise up above the flat Great Salt Lake Desert in this orthorectified image. The surrounding salt flats are located at an elevation of about 4000 feet, while the highest summit of the mountain range, Desert Peak, tops out at 6800 feet.

East of the mountain range is the Great Salt Lake (right). The lake is surrounded by both mountainous and flat areas. Of note nearby is an agricultural area composed of circular fields to the north of the lake and a series of evaporation ponds along the southwestern shores, all of which are visible in the full image.

The Amazon River flows through the Amazon Rainforest before emptying its dense load of sediments into the Atlantic Ocean off the coast of Brazil. The mouth of the river is about 330 kilometres (210 mi) wide.

The close-up focuses on the intricately woven branches of the Amazon, its tributaries and its islands southeast of the rivermouth.

The large island visible here is the suitably named Ilha Grande (Big Island) do Gurupá, the second largest island of the Amazon River delta. It lies in the Brazilian state of Pará, west of Marajó and near the confluence of the Amazon and the Xingu. The island has an area of 4,864 square kilometres (1,878 sq mi).

Sicily, Italy - October 7th, 2009

The Italian island of Sicily shows more green vegetation in this image, taken in early autumn, than it does in the hotter and drier summer months (click here for an image of the area in summer). The skies are virtually cloud free, and the summit and flanks of Mount Etna are clearly visible as a dark brown area near the eastern shores.

In the upper right corner, the Strait of Messina separates Sicily from the Italian mainland region of Calabria. Also visible near the top of the image are the Aeolian Islands, also known as the Lipari Islands, arranged in an arched shape in the Tyrrhenian Sea.

Kamchatka Peninsula, Russia - October 7th, 2009

The Kamchatka River runs eastward for 758 kilometers (471 mi) through Kamchatka Krai in the Russian Far East towards the Pacific Ocean.  The river starts northwest of Avacha and flows north down the Central Valley, turning east near Klyuchi to enter the Pacific south of Kamchatsky Point at Ust-Kamchatsk.

In the segment of the river visible in this orthorectified image, it flows through the Central Valley between the Kamchatka or Central Range (above) and the Ushkovsky (formerly known as Plosky) volcanic massif  in the central part the peninsula.
