Two women start their descent of Structure I (as seen from Structure II) at the ancient Maya (no, not Mayan) ruins of Calakmul, México:

Structure I (a.k.a. Pyramid I) is the highest at Calakmul (by virtue of its being built on a small hill), but not the tallest. Its neighbor Structure II (a.k.a. Pyramid II) is the tallest at the site, and the largest (in bulk) too — standing about 50 meters / 160 feet tall (these numbers vary depending on the source you’re looking at). Structure I is just a few meters shorter than Structure II, meanwhile Structure II’s base is some 120 meters (390 feet) square.

Translation: they’re both really big…
