Walking south from Estructura III you come to Estructura I, Calakmul’s second great pyramid, which is nearly as big as Estructura II. (American botanist Cyrus Lundell named the site Calakmul, Maya for ‘two adjacent mounds,’ in reference to the pair of then-unexcavated pyramids that dominated the site.) The steep climb pays off handsomely with top-of-the-world views.
