.003 Megaton Cache
That's the amount of explosive force this geocache could release if I converted it to a nuclear bomb. .003 megatons is the equivalent of 3000 tons of TNT!
A truly staggering amount of destructive power given that the container I used for this cache is barely the size of my thumb.
I sense your skepticism so let me run the numbers for you.
My point of comparison is the US military’s B61 thermonuclear gravity bomb:
Mass: 715 lbs.
Length: 141 in.
Diameter: 13 in.
The B61’s standard warhead contains 2 kg of uranium-235 and has a variable yield but let's just set it at 300 kilotons to make the math easier.
Measuring less than 2 inches, the Megaton cache container is roughly 1% the size of the B61.
Thus a nuclear bomb scaled down to the size of this geocache would yield 3,000 tons (300,000 x 1% = 3,000) of explosive energy.
To put this destructive force in perspective, if this geo-nuke were to detonate, every structure between the hide location and Lake Nagog would be destroyed or severely damaged.
The Halifax disaster of 1917 provides a historical comparison. A cargo ship laden with explosives detonated in the harbor of Halifax, Nova Scotia. The explosion, which was estimated to have the explosive force of 3000 tons of TNT, killed 2000 people, injured over 9000 and destroyed thousands of buildings.
So there you have it folks, the .003 Metaton Cache!
This will all make sense once you find the cache…if you can overlook the fact that turning a geocache into a nuclear bomb is an utterly ludicrous idea.
The Metaton Cache is hidden on the slope of a small stream valley so I would advise against searching for it if the ground is wet or snow-covered.
This cache is above the ground and its hide location is of modest proportions.

Please be nice to nature.
Also, please note the location and orientation of the cache container before you retrieve it and put it back just as you found it.
Thank you for your consideration.
