Pick up from bottom of skiing slope (5)
I believe the answer is:
glean
'pick up' is the definition.
(thesaurus)
'bottom of skiing slope' is the wordplay.
'bottom of' indicates one should take the final letters.
'slope' becomes 'lean' (I've seen this before**).
The last letter of 'skiing' is 'g'.
'g'+'lean'='GLEAN'
'from' is the link.
(Other definitions for glean that I've seen before include "Collect bit by bit, often with difficulty" , "Pick up (information)" , "Gather after reaping" , "Collect gradually from scattered sources" , "Gather (info or the harvest)" .)
