Ship's parts stuck, to begin with, in a gateway to the Dales (6)

'a gateway to the dales' is the definition.
I can't tell whether this defines the answer.

'ship's parts stuck to begin with in' is the wordplay.
'ship's' becomes 'haes' (I can't explain this - if you can you should give a lot more credence to this answer).
'parts' indicates an anagram (I've seen 'parts of' mean this).
'to begin' says to take the initial letters.
'with' becomes 'w' (abbreviation).
'in' means one lot of letters goes inside another.
The first letter of 'stuck' is 's'.
's'+'w'='sw'
'sw' with letters rearranged gives 'ws'.
'haes' going around 'ws' is 'HAWSES'.

Can you help me to learn more?
