Lying near the center of this image is Lake St. Clair, between Lake Huron to the north and Lake Erie to the south. It is connected to the former by the St. Clair River, and to the latter by the Detriot River.

West of the lake is the state of Michigan, USA, while to the east lies the Canadian province of Ontario. The city of Detroit, USA, and its extensive suburbs can be seen on the western shores of the Detroit River, while the city of Windsor lies on the eastern shores in Canada.

The lake is part of the Great Lakes system, although it is rarely counted as one of the Great Lakes. Here, Lakes St. Clair and Erie appear bluish-green and clouded with light tan sediments. Lake Huron, on the other hand, appears dark blue except for a small area framing its southern shores.

The Jabal Kharaz mountains stand out just a short distance from the coast of Yemen along the Gulf of Aden in center of the shoreline visible in this orthorectified image.

Jabal Kharaz is a mountainous range of limestone and granite formations extending to within 1 mile of the coast. The summit, 850 meters high, rises about 15 miles northeast of Ras al Arah. A ruin of roughly hewn stone stands on the west side of the usmmit.

Notch, a 2051m high peak, stands about 2 miles north of Jabal Kharaz. A range which extends about 65 miles east from Notch lies from 20 to 25 miles inland and attains hieghts of 914 to 1981m.

Diverse Terrain of Pakistan

Pakistan - October 5th, 2009

Pakistan covers 340,403 square miles (881,640 km2), approximately equalling the combined land areas of France and the United Kingdom. Its eastern regions are located on the Indian tectonic plate and the western and northern regions on the Iranian plateau and Eurasian landplate.

Apart from the 1,046-kilometre (650 mi) Arabian Sea coastline, Pakistan’s land borders total 6,774 kilometres—2,430 kilometres (1,509 mi) with Afghanistan to the northwest (upper left), 523 kilometres (325 mi) with China to the northeast, 2,912 kilometres (1,809 mi) with India to the east (right) and 909 kilometres (565 mi) with Iran to the southwest (lower left).

The northern and western highlands of Pakistan contain the towering Karakoram and Pamir mountain ranges, which incorporate some of the world’s highest peaks, including K2 (28,250 ft; 8,611 m) and Nanga Parbat (26,660 ft; 8,126 m). A small part of these mountain ranges is visible in the upper right corner.

The Balochistan Plateau lies to the west, and the Thar Desert and an expanse of alluvial plains, the Punjab and Sind, lie to the east. The 1,000-mile-long (1,609-km) Indus River and its tributaries flow through the country from the Kashmir region to the Arabian Sea. The river’s course can be clearly seen through the center of this image, reaching from the mountains in the north to the sea in the south.

Pakistan has four seasons: a cool, dry winter from December through February; a hot, dry spring from March through May; the summer rainy season, or southwest monsoon period, from June through September; and the retreating monsoon period of October and November. The onset and duration of these seasons vary somewhat according to location. Rainfall can vary radically from year to year, and successive patterns of flooding and drought are also not uncommon.
