River makes camp too unsafe? (7)
I believe the answer is:
potomac
'river' is the definition.
(I've seen this before)
'camp too unsafe?' is the wordplay.
'unsafe?' is an anagram indicator (I've seen 'unsafe' mean this).
'camp'+'too'='camptoo'
'camptoo' anagrammed gives 'POTOMAC'.
'makes' is the link.
(Other definitions for potomac that I've seen before include "to which banks in Washington have access" , "Capital outflow" , "Water flowing" , "Washington's river" , "River of Washington DC" .)
