Regular readers may recall that I put a visit to Tulainyo Lake on my bucket list a few years ago. Last week I did it.
Impossibly remote, otherworldly beauty, and an enduring mystery. Just how deep was this lake? Wikipedia claims not to know. Measuring it is non-trivial. A worthy challenge.
The skinny: This relatively small alpine lake is about 117 m deep! That makes it the 25th deepest natural lake in North America, and by far the deepest lake on Earth for its size.
