The rough limestone offered purchase enough to prevent sliding or slipping, and the mass of stones was held by its own weight and could even take the thrust of a beam of juniper or pine inserted into the walls to support other building elements or shelving structures. The stones were so cunningly fitted together that no chink of light showed through, and no errant blasts of winter wind could find an opening. The effect was also quite attractive, with a pleasing texture, especially seen from outside.

Inside, the stone windbreak wall was all but hidden by a second wall made of panels of rawhide-untreated leather that dried stiff and hard-attached to wooden posts sunk into the dirt floor. The panels began at ground level but extended above the stone walls vertically to a height of eight or nine feet. Ayla recalled that the upper panels were lavishly decorated on the outside. Many of the panels were also painted with animals and enigmatic marks on the inside, but the colors seemed less bright because it was darker inside. Because Marthona's structure was built against the slightly sloping back of the cliff, underneath the overhanging shelf, one wall of the dwelling was solid limestone.

Ayla looked up. There was no ceiling except the underside of the stone ledge some distance above. With the exception of occasional downdrafts, smoke from fires rose over the wall panels and drifted out along the lofty stone, leaving the air essentially clear. The cliff overhang protected them from inclement weather, and with warm clothing the dwellings could be quite comfortable even when it was cold. They were fairly large, not like some of the cozy, easy to heat, fully enclosed, but often smoke-filled little living spaces she had seen.

While the wood and leather walls offered protection from wind and rain that might blow in, they were designed more to define an area of personal space and provide some measure of privacy, at least from eyes if not ears. Some of the upper sections of the panels could be opened to admit light and neighborly conversations, if desired, but when the window panels were closed, it was considered courteous for visitors to use the entry and ask for admittance, not just call out from outside or walk in.
