Bolivia and Argentina - September 29th, 2009

Several volcanoes and mountains are visible in this orthorectified image of Bolivia and northwestern Argentina. The peak that looks similar to a bull’s eye, as it is surrounded by a smoother, flatter ring, is called Cerro Colorado, and is located directly on the Bolivia-Argentina border. The other peaks of interest, Cerro Lípez and Uturuncu, are both located fully in Bolivia.

Cerro Lípez is a stratovolcano in the Cordillera de Lípez in Sud Lípez province of Potosí Department, in the southwest of the country. It has twin peaks and rises to 5,929 m. It can be seen here northwest of Cerro Colorado, near the top of the image.

Uturuncu, or Uturunku, is a stratovolcano and the highest summit in southwestern Bolivia, visible southwest of Cerro Colorado at the center of the left edge of the image. It displays young well-preserved lava flows at its summit which were erupted during the Pleistocene period. The volcano also shows fumarolic activity.

Several large cities appear as grey areas near the major waterways of the states of New York, New Jersey and Pennsylvania in northeastern United States of America.

The city of New York can be seen just above the center of the image. The island and borough of Manhattan lies between the Hudson River (left) and the East River (right). West of Manhattan and the Hudson is the city of Newark in the neighboring state of New Jersey.

Further south, the city of Philadelphia is visible on the west banks of the Delaware River, which separates part of New Jersey (east) from Pennsylvania (west).

The Active Delta of the River Po in Italy, South of Chioggia

The River Po flows eastward across northern Italy to the Adriatic Sea. Here, its delta can be seen along the shores of the sea. Along the coast, northwest of the delta, is the coastal town of Chioggia in the Veneto Region, situated on a small island at the southern entrance to the Lagoon of Venice. It appears here as a white area at the top center.

The most recent part of the Po Delta projects into the Adriatic between Chioggia and Comacchio. It contains channels that actually connect to the Adriatic and on that account is called the active delta by the park authorities, as opposed to the fossil delta, which contains channels that used to but no longer connect the Po to the Adriatic.

The active delta was created in 1604 when the city of Venice diverted the main stream, the Po grande or Po di Venezia, from its channel north of Porto Viro to the south of Porto Viro in a channel then called the Taglio di Porto Viro, or “Porto Viro cut-off.”

Tasmania is an Australian island and state. It is located 240 kilometres (150 mi) south of the eastern side of the continent, from which it is separated by the Bass Strait. The state includes the island of Tasmania – the 26th largest island in the world – and the surrounding islands.

Visible here is the Tarkine, a large wilderness area in the far north-west of Tasmania. It is the largest remaining temperate rainforest area in Australia and one of the largest in the world.

The exact demarcation of this area has yet to be finalized but is bounded roughly by the Southern Ocean to the West, the Arthur River to the north, the Pieman River to the south, and the Murchison Highway to the east. This wilderness covers approximately 3,800 km².

The Tarkine contains pristine rainforest about 1,800 km² and eucalypt forest about 400 km², a number of wild rivers, exposed mountains, magnesite cave systems and extensive coastal heathlands. There are also large sand dune areas extending several kilometres inland.
