US peak — top it in style (2,7)

I believe the answer is:

el capitan

I'm a little stuck... Click here to teach me more about this clue!

'us peak' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'top it in style' is the wordplay.
'top' becomes 'cap' (both can mean to beat or outdo).
'in' indicates putting letters inside.
'style' becomes 'elan' (synonyms).
'cap'+'it'='capit'
'capit' put inside 'elan' is 'EL CAPITAN'.

Can you help me to learn more?

(Another definition for el capitan that I've seen is " Spanish officer - Yosemite rock face".)

I've seen this clue in The Times.
