Discover caribou near the hides (7)
I believe the answer is:
unearth
'discover' is the definition.
(to unearth is to discover or find)
'caribou near the hides' is the wordplay.
'hides' says the answer is hidden in the clue.
'UNEARTH' can be found hidden inside 'caribou near the'.
(Other definitions for unearth that I've seen before include "Exhume" , "reveal" , "Discover" , "Track down" , "Cut a certain wire" .)
