Not At Posted Coordinates.
Hidden on Pi day. See some of the awesome views that the CCL has to offer! Choose correct path and there will be all trail hiking with very minor bush avoiding more than whacking... 
To get the correct coordinates you will have to work out a couple of equations using Pi:
The circumference of a circle is 3039.52 inches, what is the diameter of the circle? Only use the first 3 digits of Pi, use the first 3 digits of the diameter as the last 3 digits of the Latitude.
The radius of a circle is 16.34 inches, what is the area of the circle? Only use the first 3 digits of Pi, use the first 3 digits of the area as the last 3 digits of the Longitude.
The regular hazards like poison oak, stickers, star thistle, ticks and snakes can be found in the area and possibly some larger wildlife as well.
Great Views in the area. Please replace the cache as found after logging. BYOP. Have Fun! 
You can validate your puzzle solution with certitude.
