In archipelago, big dry area (4)

I believe the answer is:

gobi

'area' is the definition.
(Gobi is an example)

'in archipelago big dry' is the wordplay.
'in' indicates a hidden word.
'GOBI' can be found hidden inside 'archipelago big dry'.

(Other definitions for gobi that I've seen before include "arid area" , "Desert of central China" , "Mongolian expanse" , "Large desert plateau of southern Mongolia and northern China" , "Large, mainly Mongolian, desert" .)

I've seen this clue in The Telegraph.
