This suggests that cave sandals were valuable objects, worth storing for future use rather than discarding after a single trip.

Or that they were left as part of a ritual practice of deposition — placing objects in the cave as an act of meaning rather than merely abandoning what was no longer needed.

The petroglyphs — carved line glyphs — include geometric designs: cross-hatched patterns, rectilinear shapes, spirals.

These were not casual scratches.

They were deliberate and organized, requiring time to execute in an underground setting.
