Definition

From impenetrable + -ness.

He did not know why it was, but the beetling crags above him, the consciousness of the marvellous plains below, the rhythmic murmur of the wind in the pine trees near at hand, the curious impenetrableness of the old earth, the kingship of death asserting itself in the motionless brute which he had killed, but which he was powerless to make alive again--all these weird and unaccustomed influences seemed to be clutching at his imagination, taking liberties with his sense of identity. — Peak and Prairie: From a Colorado Sketch-book, Anna Fuller
