If Quzah is inaccessible, what about standing elsewhere within valid Muzdalifah after Fajr?

Book of Hajj: Prayers, Standing at Muzdalifah, and Departure to Mina

• Only the summit of Quzah qualifies
• The pilgrim must return to Arafat
• Any pause after Fajr is prohibited
• It is valid; closeness to Quzah is not a condition
