Has anyone ever found or placed a letterbox in an underwater location?
I'm not talking about the ones that have ended up in the drink through
some mishap or other, or ones where the placer wasn't paying attention
to high water marks, but ones that have been knowingly and purposefully
hidden in a location that is under the water's surface at least part of
the time?
If so, what kind of container was used? How was it anchored in place
to keep it from floating away (to keep the contents dry, it would have
to have air in it, and therefore be bouyant)?

No answers, but love the idea!
One thought... don't have a log book, just a stamp.

I considered doing so previously (and still have my idea about what/where to
do it) but have not come up with a great solution.
Here are my thoughts:
a) People already seem to have a hard enough time putting back together
above-water boxes (i.e. sealing up the ziplock bags, putting stuff back in
as they found it, etc
b) People seem to have a hard enough time putting the box back into it's
hiding spot at all.
c) Noting a) and b), my faith that an underwater box would be properly
re-packed and re-placed is low. I would hate to see the box become
water-logged, and the log book ruined.
My thoughts were on a box that was sunken, and hauled out via a rope. This
means that it's got to have no airspace left within, and needs to be full of
something heavy. I didn't want a buoyant box b/c I didn't want others
accidentally discovering it.

There was one placed in Lake Michigan once upon a time, that required scuba
diving at a shipwreck, IIRC. But I can't recall who placed it. Someone
else might remember.

I've seen temporary boxes at the end of a line in a pond and a night event box planted on a dock with glow sticks.?? I've discussed planting some along Darby creek and a couple of islands on Hargus lake accessible only by kayak or canoe but they are not likely to have many visitors.? You would just need to attach the box to a brick or use a larger lock and lock with concrete in the bottom third or so.? Fisherman would probably snag the line if tied to shore if care is not taken.? Unless we are talking SCUBA here.

These containers wouldn't solve the bouyancy problem, but in mid-
Missouri the waterproof container of choice is the lock 'n lock...it
easily withstood the rigorous scientific testing we subjected it to,
which you can read about at http://midmoletterboxing.blogspot.com/

I too have considered an underwater placement, but have dismissed the
idea as impractical.
There are some really terrific water proof containers such as Pelican
boxes or Zero Boxes, but unfortunately they are really pricey. I have
run some surprise unofficial tests on both brands here on the Kern
River as well as some other rivers. A war surplus ammo can would work
for a while, if you found one with good seals, but in the long run
someone may not close it properly.

I found one in Oklahoma several years ago. It was inside some kind
of waterproof bag with a rock to weigh it down, attached to a rope
hanging from a dock in a small pond. The clues said nothing about
where it was, just go to the end of the dock, so was fun to figure it
out. It was dependant on each finder resealing the bag correctly, so
a waterproof box would be good for redundancy.
I have thought about placing a box for snorklers in shallow water so
you could get to dry land to stamp in. I thought about using
threaded PVC pipe with caps on each end to house the log and stamp.
I figure if PVC is made to contain water without leaking, it should
keep water out, too. Just not sure how it would last in salt water
and exposure to sun. If it was in fresh water in shade, it might
work. Of course, it would eventually get green and slimy, but maybe
that could be the theme of the box. Beware the Green Slime!

It was BindleBabe of Michigan who placed it. She hid it off the shore
of Milwaukee, WI and you are correct it required a dive. I was sorry
my dad was no longer among the living so he could retrieve it for me.
If I remember correctly, it was first found by a geocacher, even though
it was a letterbox. Not sure what the current status is...

I was musing about how to overcome the bouyancy factor. Part of it would be putting weights inside the box, and the other would be putting it under a rock. Methinks some tests are in order.....

Paul in SF planted one of the first, if not THE first underwater boxes. I believe it had something to do with Atlantis?
Probably could find the clue if you did a little sleuthing.

Marine dry boxes, scuba soft weights, and a lock & lock letterbox inside,
everything double bagged, tied to something with sturdy nylon rope. Works like
a charm!!!

Cool data. It would be interesting to see how it fares in a
freeze/thaw cycle, as water expands when it freezes and may do some
unpredictable stuff.

The real test will be when it is opened and resealed (or not) by

Actually, I would think that the *real* test would be if someone tries
to open it while still under water :-O

I have hunted for one that was missing. This one was anchored by
fishing line in a stream. I found one that was in perfect shape that
was inside a lock 'n' lock, with the log inside a small rafting dry
bag and weighted on top with a large rock.
I have always wondered about the safety of that Bindle Babe box.
According to the clue, it was as 90 feet, requiring a bounce dive. At
that depth an exit and immediate re-entry would be a very poor idea.
You would have to do an extended surface interval to prevent
decompression sickness. As much as I would've loved to have gone for
that one, I didn't make it happen. As far as I know, it had at least
one recorded find. Funhog

I'm experimenting now with PVC pipe.? I'm getting good results, but I still need to tweak the volume to ballast ratios.I'll let you know.There must be some mathematical formula out there that'll tell me this without having to do this trial and error stuff.

Here it is.Good ol' internet search....
Buoyancy is a factor of the weight of the water being displaced by the object.If the object weighs less than the volume of water it displaces, the object has positive buoyancy, and will float.If the object weighs more than the volume of water it displaces, the object has negative buoyancy, and will sink.If the object weighs the same as the volume of water it displaces, then it has neutral buoyancy.The total downward force is the weight of the object, and the total upward force is the weight of the water displaced.
So all I have to do to figure out how much ballast to use is to figure out the volume of water displaced, and then figure out the weight of?that amount of?water.That number of pounds (I'm using lead fishing sinkers for ballast; gravel just doesn't cut it), plus the weight of the container itself should be more than enough to keep it on the bottom.

Hey, Pakrat,,,
You can figure out the weight, etc. and keep it on the bottom,,, IF
it's non-moving water... if it has a current, it may tend to bobble,
if the weight isn't sufficient... I'm guessing you're going to have
it tethered with something so it won't head off towards an ocean, if
it IS moving water... :-)

Weight of water: A pint a pound. (roughly)

I was looking for some unrelated stuff at an outdoor outfitter site
and stumbled upon a product called Aloksak. These are waterproof bags
that are advertised to stay dri to a depth of 200 feet. I'm not sure
I'd rely solely on one of these, but they might work inside another
container, and they could conceivably be loaded with ballast. Here's a
link to what I believe is the manufacturer's site. There are different
sizes, and options to purcchase sets of mixed sizes. The price doesn't
seem too bad, considering the product claims. Check out this site:

The volume of water (and thus, the weight) also depends on the temperature.?When water gets colder and freezes it expands, which could throw off the formula somewhat. When dealing with buoyancy issues, you generally?have to be more precise than that (re: a pound a pint). It works out to 1.0425 pounds per pint. If you're talking about a little thing like a letterbox it probably doesn't matter, but that .0425 pound would certainly add up if we're talking about big stuff like submarines.
