After bad weather, died on mountain (7)
I believe the answer is:
snowdon
'mountain' is the definition.
(Mount Snowdon in Wales)
'after bad weather died on' is the wordplay.
'after' says to put letters next to each other.
'bad weather' becomes 'snow' (snow might be considered bad weather).
'died' becomes 'd' (abbreviation next to the year of someone's death).
'snow'+'d' is 'snowd'.
'snowd'+'on'='SNOWDON'
(Other definitions for snowdon that I've seen before include "Highest point of England and Wales" , "Highest mountain in Wales" , "that is looked up to in Wales" , "High spot in Wales" , "Welsh mountain" .)
