Track across icy glen apparently leads to cool forest (5)
I believe the answer is:
taiga
'cool forest' is the definition.
'taiga' can be an answer for 'forest' (I've seen this before). I am not certain of the 'cool' bit.
'track across icy glen apparently leads' is the wordplay.
'leads' indicates taking the first letters.
The first letters of 'track across icy glen apparently' is 'TAIGA'.
'to' is the link.
Can you help me to learn more?
(Other definitions for taiga that I've seen before include "Northern region" , "tree-covered region" , "Swampy forest south of tundra" , "northern forest" , "Forested northern land" .)
