The real coordinates are:
N 101001° 100111.11011100111'
W 1010110° 1011.001010011011'
These coordinates are in binary.
Binary is somewhat similar to our normal number system (known as decimal), but there are several differences. In decimal, each place value is ten times the value of the place to its right. In binary, however, each place value is only twice the value of the place to its right.
Also, binary uses only two numbers (0 and 1). This is because any positive whole number can be formed by adding some of the binary place values.
Binary is used internally in most computers. Whenever you type a lowercase "a", the computer registers it as its ASCII code which is 97 in decimal and 01100001 in binary.
To convert a binary number (e.g. 10010.11) to decimal:
- Find the place values for all the digits.
16s |
8s |
4s |
2s |
1s |

Halves |
4ths |
1 |
0 |
0 |

- Add the place values for all the digits with a 1. (Skip the digits with a 0, since that represents nothing.)
16 + 2 + 1/2 + 1/4 = 18.75
- The sum is the same as the decimal equivalent of the binary number, so the binary number 10010.11 is the same as the decimal number 18.75.
You will need to convert the cache coordinates to decimal. You can do this either by using an online converter, or you can convert them manually using the method above. Caution: Some online binary-to-decimal converters don't work for digits after the decimal point.
Note: When you have finished converting the coordinates, round them to the nearest 3 decimal places.
The cache is a small Lock-n-Lock container with room for some small trade items. Bring your own pen/pencil to sign the log. The original trade items were a keychain, a 1937 buffalo nickel, and a 1920 Canadian cent.
Happy hunting, and remember, binary rocks!
