Title: Palü Lake
Passage: Palü Lake (Romansh: "Lagh da Palü", German "Palüsee") is a lake below Piz Palü in the Grisons, Switzerland.  Water from Palü Glacier feeds into the lake.  In 1926, a dam was built enabling use of the lake as a reservoir.
Title: Oberhalbstein Alps
Passage: The Oberhalbstein Alps (German: "Oberhalbsteiner Alpen" ) or Platta Group (Italian: "Alpi del Platta" ) are a mountain range in the Alps of eastern Switzerland and northern Italy.  They are considered to be part of the Central Eastern Alps.  The Oberhalbstein Alps are separated from the Lepontine Alps in the west by the Splügen Pass; from the Plessur Range in the north by the river Albula; from the Albula Alps in the east by the Septimer Pass and the river Gelgia; from the Bernina Range in the south by the Val Bregaglia.
Title: Piz Palü
Passage: Piz Palü is a mountain in the Bernina Range of the Alps, located between Switzerland and Italy.  It is a large glaciated massif composed of three main summits, on a ridge running from west to east.  The main (and central) summit is 3,900 metres high and is located within the Swiss canton of Graubünden, although the border with the Italian region of Lombardy runs about 100 metres west of it at almost the same height (3,898 m).  The western summit (3,823 m; on the international border) is named "Piz Spinas" and is the only one not covered by ice.  The eastern summit (3,882 m; within Switzerland) is named "Piz Palü Orientale".  The name "Palü" derives from the Latin "palus", meaning a swamp, and the mountain is said to be named after the "Alpe Palü", a high alpine pasture some 4 km to its east.
