Queen in arena, diva's perhaps showing range (6,6)
I believe the answer is:
sierra nevada
'range' is the definition.
(Sierra Nevada is an example)
'queen in arena diva's perhaps' is the wordplay.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'in' indicates putting letters inside.
'perhaps' indicates an anagram.
'arena'+'divas'='arenadivas'
'arenadivas' with letters rearranged gives 'siranevada'.
'er' put into 'siranevada' is 'SIERRA NEVADA'.
'showing' acts as a link.
(Other definitions for sierra nevada that I've seen before include "Mountain range in Spain or E. California" , "Mountains" , "Range of Western US" , "Andalusian mountain range" .)
