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.

An ultra-prominent peak, or Ultra for short, is a mountain summit with a topographic prominence of 1,500 metres (4,900 ft) or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence.
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.
Chuprene Glacier is a 2.1 nautical miles long glacier draining the northwest slopes of Imeon Range on Smith Island in the South Shetland Islands, Antarctica. It is situated northeast of Bistra Glacier, southwest of Yablanitsa Glacier and northwest of Krivodol Glacier, Pashuk Glacier and Rupite Glacier, and flows southwest of Drinov Peak and Popovo Saddle, and west of Slatina Peak and Varshets Saddle southwestward along the northwest slopes of Antim Peak and Evlogi Peak into Drake Passage south of Villagra Point and north of Garmen Point. Bulgarian early mapping in 2009. The glacier is named after the settlement of Chuprene in northwestern Bulgaria.
