Summit

Point on a surface with a higher elevation than all immediately adjacent points

A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term top (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation.
