On a really basic level, stalagmites and stalactites are rock formations caused by mineral deposits over a really long period of time.

Walking through caves and all, but one aspect takes the bacon, if you will.  There’s a type of formation called a “sheet” formation.  Sometimes it’s flowy and colored such that it looks like bacon.  In fact, it’s often referred to as “cave bacon”.  The worst part of all is that it’s rather frowned upon to bring a baconator into the caves, so you have to wait to snack until afterward.
