Mountain lake (4)

I believe the answer is:

tarn

'mountain lake' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for tarn that I've seen before include "High water" , "Small mountain lake" , "Mountain pool: French department" , "Scottish mountain lake" .)

I've seen this clue in The Times, The New York Times, The Mirror, the Evening Standard, The Independent, The Guardian and The Telegraph.
