The geology of Saba represents a young Pleistocene volcanic island. The oldest rocks are overlain by the Sugar Loaf-White Wall Formation shallow marine limestone. Mt. Scenery is the island's highest point and records a pyroclastic volcano that is the highest point in the Kingdom of the Netherlands. Zion's Hill or Hell's Gate is part of a basaltic andesite lava flow. [1]
South Georgia and the South Sandwich Islands (SGSSI) is a British Overseas Territory in the southern Atlantic Ocean. It is a remote and inhospitable collection of islands, consisting of South Georgia and a chain of smaller islands known as the South Sandwich Islands. South Georgia is 165 kilometres (103 mi) long and 35 kilometres (22 mi) wide and is by far the largest island in the territory. The South Sandwich Islands lie about 700 kilometres (430 mi) southeast of South Georgia. The territory's total land area is 3,903 km2 (1,507 sq mi). The Falkland Islands are about 1,300 kilometres (810 mi) west from its nearest point.
Ross Island is an island formed by four volcanoes in the Ross Sea near the continent of Antarctica, off the coast of Victoria Land in McMurdo Sound. Ross Island lies within the boundaries of Ross Dependency, an area of Antarctica claimed by New Zealand.
This article lists extreme locations on Earth that hold geographical records or are otherwise known for their geophysical or meteorological superlatives. All of these locations are Earth-wide extremes; extremes of individual continents or countries are listed in separate articles under the Extreme points by region section. For other lists of extreme places on Earth, see Lists of extreme points. For more detailed meteorological and climatic records, see List of weather records.
In topography, prominence measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's key col is a unique point on this contour line and the parent peak is some higher mountain, selected according to various criteria.
This is a list of the extreme points of Ireland – the points that are farthest north, south, east or west in Ireland. It includes the Republic of Ireland and Northern Ireland.
This is a list of the extreme points of Europe: the geographical points that are higher or farther north, south, east or west than any other location in Europe. Some of these positions are open to debate, as the definition of Europe is diverse.
A list of highest points typically contains the name, elevation, and location of the highest point in each of a set of geographical regions. Such a list is important in the sport of highpointing. A partial list of highpoint lists is below:
The topographic isolation of a summit is the minimum distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point. It can be calculated for small hills and islands as well as for major mountain peaks and can even be calculated for submarine summits.
