To move aimlessly into a great deal of snow (5)
I believe the answer is:
drift
'to move aimlessly' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for drift that I've seen before include "move around without end" , "General idea (of snow?)" , "Implication of what's been said" , "go with the tide" , "General trend - current travel" .)
