The peak is a valley inverted
The inverted valley is a peak
"When a tourist coming from a well-explored country, suddenly reaches the borderland of a terra incognita, hedged in, and shut out from view by a formidable barrier of impassible rocks, he may still refuse to acknowledge himself baffled in his exploratory plans. Ingress beyond is forbidden. But, if he cannot visit the mysterious region personally, he may still find a means of examining it from a short distance as can be arrived at.
Helped by his knowledge of landscapes left behind him, he can get a general and pretty correct idea of the transmural view, if he will only climb to the loftiest summit of the altitudes in front of him.
Once there he can gaze at it, at his leisure, comparing that which he dimply perceives with that which he has just left below, now that he is, thanks to his efforts, beyond the line of the mists and the cloud-capped cliffs."
