On the north-west side of the great central cone of Mount Ossa a wide fissure runs right across the mountain from Mega Keserlì to Tságezi. On the south side of this fissure and at the base of the central cone lies the village of Spiliá, which is to be distinguished from another village of the same name near Laspochori at the eastern entrance to Tempe. To the north of the fissure rises a peak known as Pláka, which is the part of Ossa that directly overhangs Tempe. A little below the bare rocky summit of this peak, which rises to a height of at least 3,500 feet, and on its south side about an hour's walk from Spiliá, is a cave, which, though long known to the inhabitants of the district, has never before been visited by archaeologists.
