Clue: Salient, good point following a lot of rubbish (5)
Answer: BULGE
Explanation: Definition: Salient
A charade of BUL[l] ('rubbish') minus the last letter ('a lot of') plus G ('good') plus E ('point' of the compass). I think of 'salient' as angular, but BULGE as rounded, but they are both prominences.
