AbstractChultunes— underground pits carved into bedrock — have been reported by the hundreds in the Maya region, yet debate on their principal use continues to this day. Sincechultuneshave not yielded solid data to answer the questions posed by Maya archeologists, they are sometimes not completely excavated or reported in detail. This article presents a review of previous work onchultunesin the Maya lowlands, followed by the presentation of new data from sixchultunesexcavated at archaeological sites in northwestern Petén, Guatemala. I argue that, although these underground features were primarily used for utilitarian purposes, there is strong evidence thatchultunesalso had ritual importance to the ancient Maya. The variability in the shape, size, and associated cultural materials, including macrobotanical remains, justifies further in-depth investigations ofchultunes. Archaeologists should consider investigating these features more systematically, as a larger comparative sample ofchultunescould aid in assessing whether there are local patterns of construction, use, and reuse. Thus, excavations of these features should be encouraged.
