The high points are generally seen in the narrow crevices, while the rooms of generous length and breadth are usually low, many of the largest having an average of five feet or even less. Although there is frequent intersection of crevices, and each chamber has passages leading out on every side, the general direction of the cave is said to be northwest-southeast.
We were now on the chasm’s brink, looking down into its unfathomable depths. This gigantic rent, hundreds of feet in width and thousands in depth, indicates that northwest-southeast line along which the volcanic forces of Ararat have acted most powerfully.
They are strung along a northwest-southeast line, their volcanoes standing in two parallel rows as if reared along two adjacent lines of fracture or folding. In the northwestern islands the volcanoes have long been extinct and are worn low by erosion. In the southeastern island. Hawaii, three volcanoes are still active and in process of building.
