Competing Interpretations: Internal Ramp vs. Stepped Core. Jean Pierre Houdan proposes an internal spiraling ramp used during construction. Keith Hamilton and others argue the same density pattern could be a stepped core rather than a ramp. Wallace's Mysteries of Antiquity suggests the denser band may represent an external ramp used to build the step core.

Jean-Pierre Houdin sees the denser spiral as evidence of an internal construction ramp for the upper portion, while some researchers argue the same density pattern could be a stepped core rather than a ramp. Debate continues!
