This pic shows the relative position of the band of limestone which was quarried for David Hutchinsons lime kiln. Local "knowledge" is that these are "Maori Caves" showing the lack of appreciation in the general community, for North Otago's industrial heritage. The limestone may have been won by mass excavation of the face of the bluff until it became so far below the surface that a bit of room-and-pillar quarrying was justified. IT looks like some 30 or 50 cubic metres of limestone may have been extracted from the small chambers excavated into the thin seam (700 - 100 thick) before the operation ceased. Much still needs to be researched about this location and its hidden of missing kiln before the geological reserve can be properly appreciated.
