From the Tuxtlas to San Lorenzo: moving a mountain without wheels
The basalt blocks for the colossal heads were transported from the Tuxtlas over tens of kilometres.

History and context
The basalts of the heads and thrones came from the volcanic region of the Tuxtlas, tens of kilometres away. Transporting blocks of many tonnes required combining slopes, rollers or plausible sledges and, above all, fluvial corridors that brought the rock to the centre.
No manual of the route has been preserved. The achievement lies in the planning visible in the result: selecting a rock, gathering food and labour, avoiding droughts and floods, and keeping intact a mass destined to change meaning.
Selecting the block in the Tuxtlas was only the beginning. It had to be freed, descent sections prepared, and ropes, wood, boats, food and people gathered without breaking a rock destined for monumental carving.
The Coatzacoalcos basin offers plausible fluvial corridors, alternated with terrestrial portages. The itinerary had to respond to rains and droughts, but no complete route has been marked: the museum can show logistical options, not a step-by-step filmed expedition.
Evidence and interpretation
Documented fact: the monumental basalt of San Lorenzo was imported over long distance from the Tuxtlas. Interpretation and caution: the exact routes and devices are not directly documented; rafts, sledges and rollers are engineering hypotheses, not a verified sequence. Expanded documentation: Geology links the basalt of San Lorenzo monuments to sources in the Tuxtlas volcanic region, tens of kilometres away. Expanded interpretation and caution: Rafts, rollers and sledges are technically possible solutions, but their exact combination and the number of participants are not documented.

The traces of movement are not a complete route
The rear of Colossal Head 2 preserves square perforations that the National Museum of Anthropology tentatively interprets as points for lifting or supporting it with timbers. They are concrete marks on the object, different from the proposed fluvial routes at regional scale. The same label suggests that part of the work could begin at the stone source and end at the destination. Observing these evidences allows separating extraction, transport and finishing. The perforations alone do not reconstruct the journey from the Tuxtlas nor prove that all monoliths were moved by an identical procedure.
