The light brownish area surrounding the peak shows a distinctive radial drainage pattern that is quite common for stratovolcanoes as the terrain falls away from the main peak.
The cave's uniqueness lies in its impressive drainage pattern, which can be shown by the presence of more than seven layers on the walls, with lateral benches and three cornices.
It allows a landowner to make reasonable alteration to the drainage pattern of his parcel, with liability only occurring when the alteration causes unreasonable harm toward neighboring parcels.
Drainage pattern, typical of hilly terrain, is sub-dendritic, sub-parallel and sub-radial, which is dictated by the structure and lithology of the area.
