In Notebooks and Journals - Vol II, under the note for Allerheiligen is
a note "C went down & visited the waterfalls."  I suspect he was
referring to the Büttensteiner Waterfalls, known today as the All
Saints Waterfalls.  

Can anyone verify this?  From Wikipedia:

"The waterfalls belonged for centuries to All Saints' Abbey, the ruins
of which are only a few hundred metres away. Because they lie in a
deeply incised and narrow valley, they were inaccessible for a long
time. Not until the early 19th century were they discovered with the
aid of ladders. In 1840 the forestry authorities built a path that
enabled access to the falls via several flights of steps and bridges.
Because it receives so many visitors it has had to renovated several
times already."

They are mentioned in Baedeker's guidebook which was reportedly used by
Twain.
