China - September 7th, 2010

This image shows the green, vegetated landscape of northeastern China. Lower, flatter terrain is light green, while more mountainous terrain is dark green. The land visible here is part of Heilongjiang Province.

Heilongjiang is a land of varied topography. Much of the province is dominated by mountain ranges such as the Greater Khingan Range and Lesser Khingan Range, Zhangguangcai Mountains, Laoye Mountains, and Wanda Mountains.

The highest peak is Mount Datudingzi at 1690 m (5545 ft), located on the border with Jilin province). The Greater Khingan Range contains China’s largest remaining virgin forest and is an important area for China’s forestry industry.

The interior of the province, which is relatively flat and low in altitude, contains the Muling River, the Naoli River, the Songhua River, the Nen River, and the Mudan River, all tributaries of the Amur’s basin, while the northern border forms part of the Amur valley. Xingkai Lake (or Khanka Lake) is found on the border with Russia’s Primorsky Krai.

Just below the center of the image, left of the river cutting through the dark green mountains, is the city of Harbin, the the capital of Heilongjiang Province. It lies on the southern bank of the Songhua River. Harbin is the tenth largest city in China (pop. 9.87 million).

North Korea - September 4th, 2009

Baekdu Mountain, also known as Changbai Mountain in China, is a volcanic mountain on the border between North Korea and China, visible near the top center of this orthorectified image.

At 2,744 m (9,003 ft), it is the highest mountain of the Changbai mountain range to the north and Baekdudaegan mountain range to the south. It is also the highest mountain on the Korean peninsula and Manchuria.

Baekdu Mountain is stratovolcano whose cone is truncated by a large caldera, about 5 km (3.1 miles) wide and 850 m (2,789 ft) deep, partially filled by the waters of the large Heaven Lake, which appears dark black here. The lake has a circumference of 12 to 14 kilometres (7.5-8.7 miles), with an average depth of 213 m (699 ft) and maximum depth of 384 m (1,260 ft).

Water flows north out of the lake, and near the outlet there is a 70 metre (230 ft) waterfall. The mountain is the source of the Songhua, Tumen (Duman) and Yalu (Amnok) rivers.

The central section of Baekdu Mountain rises about 3 mm every year, due to rising levels of magma below the central part of the mountain. Sixteen peaks exceeding 2,500 m (8,200 ft) line the caldera rim surrounding Heaven Lake.
