Tas-Salvatur Hill (Saviours Hill) is formed around yellow sandstone which also has been formed around the Qbajjar Qolla (il-Qolla s-Safra). This would suggest that both hills are formed in the same manner but that they were at different stages of being created. Is the creation of Qollas literally a line going from Qolla Bajda (The White Qolla) to Il-Qolla Is-Safra (The Yellow Small Hill) then to Tal-Merzuq Hill (Ray of Light Hill or its modern name of Tas-Salvatur Hill)?
