Admit a glacier could be transformed by this snapper (7,6)
I believe the answer is:
digital camera
'transformed by this snapper' is the definition.
'digital camera' can be an answer for 'snapper' (something that takes snaps cryptically). I'm not sure about the rest of the definition.
'admit a glacier could be' is the wordplay.
'could be' indicates anagramming the letters.
'admit'+'a'+'glacier'='admitaglacier'
'admitaglacier' anagrammed gives 'DIGITAL-CAMERA'.
Can you help me to learn more?
(Other definitions for digital camera that I've seen before include "Gadget" , "Picture taker" .)
