Mount Swannell
Mount Swannell, 1821 m (5974 ft), prominence 771 m, is a mountain in the Fawnie Range of the Nechako Plateau in the Central Interior region of British Columbia, Canada. It is located to the south of the outlet of the Entiako River into Natalkuz Lake, which is part of the Nechako Reservoir. The northernmost of the summits of the Fawnie Range and is in the northeastern end of Entiako Provincial Park, it is the only named summit of the Fawnie Range within the park. Name origin Mount Swannell, like other similar names in British Columbia, is named for Frank Swannell, a notable British Columbia Land Surveyor who mapped much of the province by foot and horseback in the late 19th and into the mid 20th Century. He mapped this region in the 1920s, producing detailed topographic and trigonometric surveys, leaving such publications as: *''Sketch Map of the echakoRiver and Lake System, 1920-21-22'' *''Topographic plan 14T1: Morice, Nanika, Tahtsa Lakes, 1923'' *''Topographic ...

Topographic Prominence
In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) 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'' (the highest col surrounding the peak) is a unique point on this contour line and the ''parent peak'' is some higher mountain, selected according to various criteria. Definitions The prominence of a peak may be defined as the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following way: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''key Saddle point, saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting pat ...
