@J.R.: Summit and apex are also used outside of topographical or geographical context. Maybe the question is probing in that direction. – KeyBrd Basher Oct 4 '13 at 7:04
    
@Key - I'd like to see the question probe in that direction – or any direction. – J.R. Oct 4 '13 at 8:00

According to these definitions, they are completely interchangeable:

Peak -

the highest level or greatest degree

Summit -

the highest point

Apex -

the uppermost point

I don't think you can refer to the apex of a turn as the summit of the turn. – Jim Oct 4 '13 at 1:21

"Peak" also has unique usages. "He peaked too early." – Lumberjack Oct 4 '13 at 1:30
    
You say, "According to these definitions". Where did you find these definitions? Did you write them yourself? If you copied them from somewhere, please acknowledge the source and, if possible, give us a link so that we can check the correctness, authority and completeness of the definitions. Thanks. – chasly from UK Sep 30 '15 at 11:26
