Quagmire

That quagmire regularly ‘swallows’ caught-up hikers’ boots

Never did I see a more dreary and depressing scene. Miles on miles of quagmire, varied only by bright green strips of comparatively solid ground, and by deep and sullen pools fringed with tall rushes, in which the bitterns boomed and the frogs croaked incessantly: miles on miles of it without a break, unless the fever fog can be called a break.

"And what was this, my beloved brother, but a vain yielding to unbridled imagination, which, like a spring confined to one spot, collects its pure clear waters, and in at once a beauty and a blessing; but which, allowed to spread abroad in every direction, oozes through the marshy earth, becomes stagnant, and is habited by the loathsome reptile. That which would have been a green haunt, with its fair fountain, is a dreary and useless quagmire. Is it not thus with the mind, Guido?"

The only way to know Shakespeare is through his works, and his works are textual quagmires.
