It would be a foolhardy man who risked his life under the leaning, waiting avalanches of rock in that gigantic split. Yet how many years had they leaned there without falling! At the bottom of the incline was an immense heap of weathered sandstone all crumbling to dust, but there were no huge rocks as large as houses, such as rested so lightly and frightfully above, waiting patiently and inevitably to crash down.
