Trendies, alas, ruined Pacific location (6,6)
I believe the answer is:
easter island
'location' is the definition.
(I know that Easter Island is a island)
'trendies alas ruined' is the wordplay.
'ruined' indicates an anagram.
'trendies'+'alas'='trendiesalas'
'trendiesalas' with letters rearranged gives 'EASTER ISLAND'.
'pacific' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for easter island that I've seen before include "Pacific site famous for its monolithic human head statues" , "Pacific spot with large carved heads" , "Pacific location with large carved heads" , "Pacific site of many monolithic statues" , "Remote place with large standing heads" .)
