That is an easy one.
First, you have to find the median temperature for Gnome, Alaska on the date of December 11, 1967. Write this down it will be important later.
Next, you need to find the hypotenuse of the Great Pyramid of Giza, then find the square root of that to the nearest 8 digits.
Next, you will need a copy of the Wall Street Journal from ... you guessed it, Dec 11, but 20 years later, 1987.
Take the median temperature, (absolute value) and then square that. Go to that page of the Wall Street Journal and go down that many lines in the page. Get the first number that is shown on that line.
This is Karin's number no doubt. If you do not believe that, then look at the number from the pyramid on the same page. Count back that many characters from the bottom of the page. Again ... Karins number. Miracles are everywhere you look
If you need any more miracles like this, I am always around.
