Note 783 — Chapter XII · —Continents And Their Peninsulas

The one strong segregating feature in primitive America was the Cordilleras, which held east and west apart. In the natural pockets formed by the high intermontane valleys of the Andes and the Anahuac Plateau, and in the constricted isthmian region, the continent afforded a few secluded localities where civilization found favorable conditions of development. But in general, the paucity of large coast articulations, and the adverse polar or subpolar location of most of these, the situation of the large tropical islands along that barren Atlantic abyss, and the lack of a broken or varied relief, have prevented the Americas from developing numerous local centers of civilization, which might eventually have lifted the cultural status of the continents.783
