I believe the answer is:

heap

I'm a little stuck... Click here to teach me more about this clue!

'there's plenty to be' is the definition.
I can't tell whether this definition defines the answer.

'in the apennines' is the wordplay.
'in' indicates the answer is hidden within the clue.
'HEAP' is hidden within 'the apennines'.

'found' acts as a link.

Can you help me to learn more?

(Other definitions for heap that I've seen before include "Mound, stack" , "Pile (of scrap?)" , "good deal" , "Wreck of a car" , "Loose pile" .)
