(right) - New Providence Island (left center), where the capital city of the
Bahamas, Nassau is located, is 34 km long and 11 km wide and covers an area
of 207 km². Nassau is the commercial and social center of the Bahamas. The
city has a large and beautiful harbor. Nassau has a warm, healthful climate,
and a colorful atmosphere that makes the city a favorite winter resort.
Eleuthera Island (right half) is 133 km long and 3 km wide. The island is generally flat and has no rivers. There are
many mangrove swamps, brackish lakes, coral reefs and shoals, and miles of
fine sandy beaches.
Eleuthera, which means "freedom" in Greek, was one of the first of the
Bahama Islands to be colonized. The darker blue water of the Northeast
Providence Channel (this is part of the Grand Bahama Submarine Canyon) is
visible across the top portion of the image. The extreme southern portion of
the Berry Islands, are discernible in the upper-left portion of the image.
Covering the lower center portion of the image are the dark blue waters of
Exuma Sound (NASA).
The Great Lakes,
Canada (NASA -
June 1991, image above). Portions of all five Great Lakes, the largest combined body
of fresh water in the world, covering an area of 246 050
km², can be seen in this high-oblique, northeast-looking photograph. Lake
Michigan alone covers an area of 57 755 km². This lake can
be seen in the center of the photograph, with Chicago on its southwestern shore.
The Great Lakes were formed about 12 000 years ago at the end of the ice age,
when glacier-carved lake basins were filled with meltwater. The lakes are
interconnected by straits, short rivers, and canals. Water from the Great Lakes
exits at the eastern end of Lake Ontario into the Saint Lawrence River, which
flows on eastward into the Atlantic Ocean.
Image from the
Aqua satellite on April 10, 2003, shows ice still clinging to shorelines in
(west to east) lakes Superior, Michigan, Huron, Erie, and Ontario. South of Lake
Ontario in New York, slivers of dark blue water are the glacier-carved Finger
Lakes (NASA, edited).

collected on August 29, 2019 (NASA). It shows meltwater loaded with glacial
sediments flowing into the Davis Strait.
