Yalour Islands (65°14?S 64°10?WCoordinates: 65°14?S 64°10?W) is a group of islands and rocks 1.5 miles (2.4 km) in extent in the south part of the Wilhelm Archipelago. The group lies 1 mile (1.6 km) northwest of Cape Tuxen, Graham Land. Discovered and named by the French Antarctic Expedition, 1903–05, under J.B. Charcot. Named for Lieutenant Jorge Yalour, Argentine Navy, an officer of the Argentine corvette Uruguay which came to the rescue of the shipwrecked Swedish Antarctic Expedition in November 1903.

The rocks observed on the Yalours and surrounding areas are predominantly igneous intrusives that have cooled deep under ground. The main rock type is grey to black gabbro composed of small crystals of grey-white feldspar and black pyroxene. The rocks here were formed by much the same process that the rest of the peninsula was formed; the Pacific plate sliding under the Antarctic Peninsula in an ocean/continent subduction-type tectonic event. This process, called orogenesis, is one of the most common ways for a mountain chain to form. The Andres and the coast ranges of North America are other classic examples of this type of tectonism. The mountain building has nearly stopped though; it is only at the very tip of the peninsula and in the South Shetland Islands that the process continues. For the rest of the peninsula, it erosion and gravity’s turn to shape the landscape.

About 8,000 pairs of Adelie penguins nest in the Yalour Islands.

Windermere is the largest natural lake in England.[1] It is a ribbon lake formed in a glacial trough after the retreat of ice at the start of the current interglacial. It has been one of the country’s most popular places for holidays and summer homes since the arrival of the Kendal and Windermere Railway’s branch line in 1847. It is in the county of Cumbria and entirely within the Lake District National Park.

The Lake District, also commonly known as The Lakes or (particularly as an adjective) Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous not only for its lakes, forests and mountains (or fells), but also for its associations with the early 19th century poetry and writings of William Wordsworth and the other Lake Poets.

Historically shared by the counties of Cumberland, Westmorland and Lancashire, the Lake District now lies entirely within the modern county of Cumbria. All the land in England higher than three thousand feet (914,4 m) above sea level lies within the National Park, including Scafell Pike, the highest mountain in England. It also contains the deepest and longest lakes in England, Wastwater and Windermere, respectively.
