Athletic Bard taking in area around Grand Canyon - wow! (5)
I believe the answer is:
amaze
'wow' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for amaze that I've seen before include "Greatly surprise, fill with wonder" , "Stagger" , "wow!" , "Greatly surprise, astound" , "Stun" .)
