The British Columbia Coast is Canada’s western continental coastline on the Pacific Ocean. The aerial distance from one end of the coast to the other 965 km. However, because of its many deep inlets and complicated island shorelines, the total length of the British Columbia Coast is over 27,000 km, making up about 13% of the Canadian coastline at 202,080 km.

The coastline’s geography is most comparable to that of Norway and its heavily-indented coastline of fjords. The great fjords of the British Columbia Coast rival those of Norway in length and depth but are surrounded by higher mountains.

Here, several inlets and fjords stand out due to their bright green color. Upon opening the full image, one can see that there are tan sediments in the northern reaches of the fjords where rivers empty into them.

The western coast of Madagascar is flanked by rust-colored sediments spilling from various rivermouths, particularly along the coast of the Melaky Region (upper half of the shoreline). Sediments are also present, although less concentrated, off the shores of the Menabe Region, bordering the Melaky Region to the south.

Moving eastward from the west coast, the central highlands can be seen in the middle of the country. From there, a steep escarpment leads down into a ribbon of rain forest with a narrow coastal forest further east. These forested areas are mostly covered by clouds here.

The massive shield volcano in the lower left quadrant of this orthorectified image, is the early Pleistocene Bolshaya Ipelka shield volcano. Although extensively eroded by glaciers, it is the largest volcanic structure of southern Kamchatka.

It has a large volcanic caldera surrounded by a ring-shaped ridge with steep inner walls and rocky outer slopes. A single unnamed Holocene cinder cone is found on the southern flank of Bolshaya Ipelka.

The conical stratovolcano to the east (right) is Opala, located on the same east-west tectonic line. Opala was constructed along the northern rim of a large 12 x 14 km wide caldera.
