Why have few physical remains survived from many pre-Hispanic Colombian cultures?

Few physical remains have survived from many pre-Hispanic Colombian cultures primarily because of the materials and environments involved in their construction. These indigenous groups built their structures largely out of wood, a material that does not endure well over time, particularly in the tropical regions of Colombia that experience moderate to high rainfall.1

Because these societies relied on perishable building materials rather than the stone or masonry often used by other major civilizations, they left behind relatively little archaeological evidence of their architectural achievements. While some cultures, such as the San Agustín, created durable stone carvings, and others like the Tairona built significant cities that were only identified through later excavations, the reliance on wood and the challenging tropical climate remain the primary reasons for the scarcity of physical remains across many of these ancient cultures.1
