Rubble found by young socialites touring Rhode Island (6)
I believe the answer is:
debris
'rubble' is the definition.
(synonyms)
'young socialites touring rhode island' is the wordplay.
'young socialites' becomes 'debs' (short for debutantes).
'touring' means one lot of letters goes inside another (touring can mean going round).
'rhode island' becomes 'ri' (US postal abbreviation).
'debs' enclosing 'ri' is 'DEBRIS'.
'found by' is the link.
(Other definitions for debris that I've seen before include "Scattered wreckage" , "Broken remains" , "Evidence of destruction" , "Refuse remains" , "Remains - wreckage" .)
