BARS::Pi Jeep Trail in Joshua Tree Natl. Park in California

These jeep trail signs were found in the Joshua Tree National Park in California.

The jeep trail signs say...

   +-----------------------+
   |       Jeep Trail      |
   | Pinkham Canyon    7mi |
   | Interstate 10    20mi |
   +-----------------------+
   +-----------------------------+
   |     Roads Not Maintained    |
   | 4-Wheel Drive Vehicles Only |
   +-----------------------------+

   the numbers are:  7  10  20  4

   the math is:  (20 + sqrt(4)) / 7^log(10) = Pi

   observe...
      sqrt(4) = 2
      20 + 2 = 22
      log(10) = 1
      7^1 = 7
      22 / 7 equals Pi truncated to two decimal places

   off-by-one math:  20 / 10 + 4 = 7-1
   off-by-one math:  20 - 10 - 7 = 4-1
   off-by-one math:  sqrt(20 - 4) + 7 = 10+1
   off-by-one math:  sqrt(20 - 7 - 4) = 4-1
   off-by-one math:  sqrt(20 - 7 - 4) = sqrt(4)+1
