Sernftal

The Panix Pass at 2407 m connects the Sernftal with the anterior Rhine valley in Grisons.

A scale model of the feature is on exhibit in the American Museum of Natural History.

The name Sernf (earlier also Sernft) is of pre-Germanic origin, either Celtic or an example of Old European hydronymy.

It derives from a hypothetical *Sarnivos, containing a PIE root *ser "to flow".

[2] The word fünf "five" is the only genuinely German word with this ending, the others are early loanwords, including Hanf "hemp" (from kánnabis) and Senf "mustard" (from sinapis), and the toponym Genf "Geneva", from Genava.
