Water for the Gods – How the Maya Directed the Rain

LiDAR scans of newly mapped Ocomtún alongside classic sites Tikal, Edzná and Palenque reveal hidden reservoirs, canals and zeolite sand filters. These hydraulic networks blended engineering, ritual and power, shaping Maya city planning, agriculture and myth in the tropical lowlands for centuries of sustainable prosperity.

Jüngste DNA-Analysen enthüllen Maya-Kontinuität trotz Kollaps: Kinder-Opferknaben in Chichén Itzá bestätigen den Hero-Twins-Mythos; Copán-Genome belegen mexikanische Einwanderung ab 400 n. Chr. PSMC-Modelle zeigen Bevölkerungs­höhepunkt 730 n. Chr., gefolgt von dramatischem Einbruch. Krankheiten nach 1500 selektierten schützende HLA-Varianten.

Valeriana Revealed: 6,500 Hidden Maya Structures Change History

It was after midnight when doctoral student Luke Auld-Thomas stumbled upon a forgotten 2013 LiDAR scan of southern Campeche. Stripping away the jungle canopy on his laptop, he watched 6,500 ghost-white structures surface across nearly 50 square miles—a metropolis later christened Valeriana, hiding in plain sight beside Highway 261. Follow Auld-Thomas’s “Google-Earth moment” as archival laser data rewrites Maya geography, reveals twin monumental precincts, a dammed reservoir and population estimates of 30–50 thousand—rivaling Calakmul. Paired with the deep-jungle find of Ocomtún, the discovery proves LiDAR can unveil both highway-adjacent megacities and wilderness strongholds. Dive in to see how ancient urban engineering is inspiring today’s climate-resilient design—and why ethical tourism matters more than ever.

Los Abuelos – a 3,000-year-old Maya city emerges from the jungle

Hidden for 3,000 years beneath Guatemala’s Petén canopy, the newly revealed Los Abuelos Maya city—part of a perfect triangular network with Petnal and Cambrayal—boasts grand-parent statues, a solar-aligned “Group E” observatory and jungle canals. Discover what the find means for Maya history—and how adventurous travellers can explore the region.
