This is a 3 Stage Multi that should be easy for geocachers of all ages. Some simple addition, subtraction and division will be required to determine the final coordinates.
At the posted coordinates (first stage) there is a sign with a map of the park and a key to the trails and Park Amenities. Use the information in the Map Key to determine the values of "A" and "B". Let "A" = total number of trails listed. Let "B" = the number of letters in the first word of the park amenity that starts with the letter'E'.
Now proceed to the second stage. Count the number of vertical posts that hold up the shelter located there and let it equal "C".
Use the values you determined for "A", "B" and "C" above to find the Final coordinates.
The Final is located at: N 45 00.(A)(B)(B-A) W092 57.(C-3)(B-A-1)(B divided by 2)
