Middle East - June 20th, 2011

This wide-swath ASAR image focuses the Dead Sea, a salt lake bordering Jordan to the east and Israel/Palestine and the West Bank to the west.

It lies in the Jordan Rift Valley, and its main tributary is the Jordan River. The valley and river appear a lighter shade of grey.

The Dead Sea is 67 kilometres (42 mi) long and 18 kilometres (11 mi) wide at its widest point. Its surface and shores are 423 metres (1,388 ft) below sea level, the lowest elevation on the Earth’s surface on dry land.


Jordan River Flowing into the Dead Sea

The Jordan River is a 251 kilometre (156 mile) long river in Southwest Asia which flows vertically through the center of this image, into the Dead Sea. The last section, between the Sea of Galilee and the Dead Sea, has the least gradient. Thus, the river begins to meander before it enters the Dead Sea, which is about 400 metres below sea level and has no outlet. Two major tributaries enter from the east during this last phase: the Yarmouk River and Jabbok River.

In 1964, Israel began operating a dam that diverts water from the Sea of Galilee, a major Jordan River water provider, to the National Water Carrier. Also in 1964, Jordan constructed a channel that diverted water from the Yarmouk River. Syria has also built reservoirs that catch the Yarmouk’s waters. Environmentalists blame Israel, Jordan and Syria for extensive damage to the Jordan River ecosystem.

In modern times, the waters are 70% to 90% used for human purposes and the flow is much reduced. Because of this and the high evaporation rate of the Dead Sea, the sea is shrinking. All the shallow waters of the southern end of the sea have been drained in modern times and are now salt flats.

In 2007, Friends of the Earth Middle East named the Jordan River as one of the world’s 100 most endangered ecological sites, due in part to lack of cooperation between Israel and the neighboring Arab states.

Mountains Around Utah Lake, USA

Utah Lake (originally named Lake Timpanogos), at 96,900 acres (392 km2), is the largest natural freshwater lake in the state of Utah and a remnant of the prehistoric Lake Bonneville. It drains via the Jordan River at its north end into Lake Bonneville’s largest remnant, the Great Salt Lake.

Despite its large surface area, the lake is shallow; it has a maximum depth of 14 feet (4.27 m) and an average depth of about 9.4 feet (2.74 m). This shallowness allows winds to easily stir up sediments from the lake’s bottom, contributing to the turbidity seen in Utah Lake’s water.

Utah Lake dominates Utah Valley in the north-central part of the state, with major cities such as Provo and Orem hemmed between the lake’s eastern shore and the Wasatch Mountains, visible along the right edge of this orthorectified image. Also visible west of the lake are the Lake Mountains, and jutting into the south portion of the lake is West Mountain, which divides Goshen Bay and Lincoln Beach. Connected to the main body of the lake are two large, shallow bays: the aforementioned Goshen Bay to the south and Provo Bay to the east, where Hobble Creek enters the lake.

The Dead Sea and Surrounding Hills and Mountains

Dead Sea - June 21st, 2009

The Dead Sea is located between Israel and the West Bank to the west, and Jordan to the east. It is an endorheic lake located in the Jordan Rift Valley, a geographic feature formed by the Dead Sea Transform.

This left lateral-moving transform fault lies along the tectonic plate boundary between the African Plate and the Arabian Plate. It runs between the East Anatolian Fault zone in Turkey and the northern end of the Red Sea Rift offshore of the southern tip of Sinai.

The Jordan River is the only major water source flowing into the Dead Sea, although there are small perennial springs under and around the Dead Sea, creating pools and quicksand pits along the edges. There are no outlet streams.

Rainfall is scarcely 100 mm (4 in) per year in the northern part of the Dead Sea and barely 50 mm (2 in) in the southern part. The Dead Sea zone’s aridity is due to the rainshadow effect of the Judean Hills. The highlands east of the Dead Sea receive more rainfall than the Dead Sea itself.

To the west of the Dead Sea, the Judean Hills rise less steeply, and are much lower, than the mountains to the east. Along the southwestern side of the lake is a 210 m (700 ft) tall halite formation called “Mount Sodom”.

The lower section of the sea appears green and crossed by parallel lines; these are the Dead Sea Dikes, extensive salt evaporation pans.

Diverse Geography of Israel

Israel - January 13th, 2009

Israel is located at the eastern end of the Mediterranean Sea, bounded by Lebanon to the north, Syria to the northeast, Jordan to the east, and Egypt to the southwest.

The sovereign territory of Israel, excluding all territories captured by Israel during the 1967 Six-Day War, is approximately 20,770 square kilometers (8,019 sq mi) in area, of which two percent is water.

The total area under Israeli law, including East Jerusalem and the Golan Heights, is 22,072 square kilometers (8,522 sq mi).

The total area under Israeli control, including the military-controlled and partially Palestinian-governed territory of the West Bank, is 27,799 square kilometers (10,733 sq mi).

Despite its small size, Israel is home to a variety of geographic features, from the Negev Desert in the south to the mountain ranges of the Galilee, Carmel, and the Golan in the north.

The Israeli Coastal Plain, the green area on the shores of the Mediterranean, is home to seventy percent of the nation’s population.

East of the central highlands lies the Jordan Rift Valley, which forms a small part of the 6,500-kilometer (4,040-mi) Great Rift Valley.

The Jordan River runs along the Jordan Rift Valley, from Mount Hermon through the Hulah Valley and the Sea of Galilee to the Dead Sea, the lowest point on the surface of the Earth.

Temperatures in Israel vary widely, especially during the winter. The more mountainous regions can be windy, cold, and sometimes snowy. Meanwhile, coastal cities have a typical Mediterranean climate with cool, rainy winters and long, hot summers.
