The crest line begins at Monte Comunitore and leads up to the peak of Macera della Morte (standing at 2,073 metres where the three Italian regions intersect).
Living in this mountainous zone are numerous species of wild animals including the Apennine wolf, deer, badgers, and the extremely rare Marsican brown bear.
[1] The area is known for its vast and lush forests of beech, white pine, oak, chestnut, maple, basswood, ash, elm, and holly trees.
In times past these structures were rather rare and functioned as important transportation routes connecting Rome and the surrounding region of Lazio with Abruzzo and the Adriatic Sea.
Traditionally, the herds travel to the area to spend the summer in these high, and relatively cooler, elevations, escaping the lowlands where little grass grows thanks to low rainfall.
For the past century and a half, on a high pasture known as Piano Roseto (a location midway between the villages of Cortino, San Giorgio and Crognaleto), a livestock raising celebration, known as the Fiera della Pastorizia has taken place in early July.
