Geocache Description:

3 waypoints have been listed along with a distance from each point to the final cache. You will have to use some math to figure out where the cache is located.

UPDATE: Over time a micro-cache went missing, others got wet. As a result there is no need to look for the micros, since the distance is now given.

The top coordinates will take you to the parking lot.

I have listed three waypoints, along with the distance from those waypoints to the final cache. You will need to find the point at which all these distances intersect. There is no need to physically visit these three locations.

You will not be required to cross or enter the river.

I suggest using true north for this cache, as it makes drawing a map much easier.
Make sure your calculator is in degrees!

Once you find the cache, please “show your work” by leaving all your math calculations, maps, or other method in the cache for others to see.

A hint for finding the cache:
Cosine law:
given any triangle with sides a,b,c
let A be the angle opposite of side a
a^2=b^2+c^2-2bc*cos(A)

Feel free to email me the final coord, for a confirmation.
