Concurrently, along a different axis, it is the low point between two peaks, so as such, is the likely 'optimal' high point in a pass if the saddle is traversed by a track, road or railway. USGS topographic map of ridges and saddles near Hazelton, Pennsylvania (closer view).
A topographic saddle is analogous to the mathematical concept of a saddle surface, with a saddle point marking the minimum high point between two valleys and the lowest point along a ridge. [2] [3] On a topographic map, passes can be identified by contour lines with an hourglass shape, which indicates a low spot between two higher points. [4]
Contrast between topographic isolation and prominence. In topography, prominence or relative height (also referred to as autonomous height, and shoulder drop in US English, and drop 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.
The Saddle has two summits: the westerly one has a trig point, but it is not obvious which one is the true summit. Munro baggers had better climb both. To descend back to the starting point, one can either retrace the ascent route, or drop south and then south east to reach the Bealach Coire Mhalagain, at NG944125 .
A view from the Saddle Mountain trail. Saddle Mountain was created around 15 million years ago in the Miocene epoch when lava flows poured down the old Columbia River valley. When the lava encountered the water at the Astoria Sea, great steam explosions and thermal shocks occurred to create a large pile of basalt rocks.
A popular and intuitive way to distinguish mountains from subsidiary peaks is by their height above the highest saddle connecting it to a higher summit, a measure called topographic prominence or re-ascent (the higher summit is called the "parent peak"). A common definition of a mountain is a summit with 300 m (980 ft) prominence.

Hippos (Ancient Greek: Ἵππος, lit. 'horse') [1] or Sussita (Aramaic, Hebrew: סוסיתא) is an ancient city and archaeological site located on a hill 2 km east of the Sea of Galilee, attached by a topographical saddle to the western slopes of the Golan Heights.
