Canopy found in the heart of Columbian shoreline wetlands (8)
I believe the answer is:
umbrella
'canopy' is the definition.
(I know that umbrella is a type of umbrella)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for umbrella that I've seen before include "Type of pine tree" , "protective cover" , "Lure lamb under it in the rain" , "Rain shield" , "The old song urges to let a smile be yours" .)
