Just beyond the Great Rotunda exists the Lake of Mystery; it’s the furthest our tour can go, as water levels beyond this point get so high the only way to go through it is floating on your back and breathing with about an inch between the end of your nose and the ceiling. Thanks to an intrepid bunch of explorers in 1955, we know that once the Lake of Mystery has been conquered, there are two similar lakes beyond. The explorers were forced to stop beyond the second lake, as a rock fall prevents any further forward movement.//Notice the measuring stick–used to monitor the lake’s level, which rises and falls with spring rains. The white is the current level—which is also what’s considered the “normal” level. During the June floods, it had reached the 22” mark (indicated in yellow).
