Hollow atop volcano (6)

Ross

I believe the answer is:

crater

(Other definitions for crater that I've seen before include "Bowl-shaped cavity, in a volcano say" , "Bowl-shaped cavity as on volcano peak" , "Lunar surface dent" , "Volcanic cavity" , "Fissure in the earth's crust" .)

I've seen this clue in the Sydney Morning Herald.
