Ankara - Elma Dag

In the 1930s a solitary black pine (pinus negra) growing on a north-facing slope half way up Ankara's "Apple Mountain" (Elma Dag: 1,862m/6,111ft; a few kilometers southeast of the city) came suddenly to scientific prominence. With the help of other evidence it enabled the geographer Herbert Louis to demonstrate that large parts of Central Anatolia were formerly forested.
