apexes
Where mountains end
Apexes is the plural of apex, meaning the highest point, peak, or tip of something.
A mountain has an apex; so does a career, a crisis, or an argument building to its climax.
The apexes of the surrounding peaks were lost in cloud.
The Latin plural apices appears in technical writing but sounds stilted in everyday speech.
