That is, the <a href="/wiki/Drainage_divide" title="Drainage divide">drainage divide</a> is a ridge along the high point of the saddle, as well as between the two peaks and so defines the major reference axis. A saddle can vary from a sharp, narrow gap to a broad, comfortable, sway-backed, shallow valley so long as it is both the high point in the sloping faces which descends to lower elevations and the low area between the two (or three or four.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup>) flanking summits. 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. </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Cliffs_Saddles_Traverses_Passes_Ascents_%26_Peaks--_from_Sources_of_Nesquehoning_creek_from_hzlt93sw-Rot90cw,_LargerType.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/f/f2/Cliffs_Saddles_Traverses_Passes_Ascents_%26_Peaks--_from_Sources_of_Nesquehoning_creek_from_hzlt93sw-Rot90cw%2C_LargerType.png/400px-Cliffs_Saddles_Traverses_Passes_Ascents_%26_Peaks--_from_Sources_of_Nesquehoning_creek_from_hzlt93sw-Rot90cw%2C_LargerType.png" decoding="async" width="400" height="225" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/f/f2/Cliffs_Saddles_Traverses_Passes_Ascents_%26_Peaks--_from_Sources_of_Nesquehoning_creek_from_hzlt93sw-Rot90cw%2C_LargerType.png/600px-Cliffs_Saddles_Traverses_Passes_Ascents_%26_Peaks--_from_Sources_of_Nesquehoning_creek_from_hzlt93sw-Rot90cw%2C_LargerType.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/f/f2/Cliffs_Saddles_Traverses_Passes_Ascents_%26_Peaks--_from_Sources_of_Nesquehoning_creek_from_hzlt93sw-Rot90cw%2C_LargerType.png/800px-Cliffs_Saddles_Traverses_Passes_Ascents_%26_Peaks--_from_Sources_of_Nesquehoning_creek_from_hzlt93sw-Rot90cw%2C_LargerType.png 2x" data-file-width="3840" data-file-height="2160" /></a><figcaption>USGS topographic map of ridges and saddles near Hazelton, Pennsylvania (closer view).
