The cache is not at the posted coordinates. Feel free to visit the building during it's operating hours as it's filled with geological information.
To get the coordinates to the final location of the cache you have to glean the proper numbers from the stratigraphic section below and enter them into the coordinate equations. To get the numbers you will want to put each stratigraphic unit into the correct order of deposition. There are stratigraphic laws that can help you in this task. Once completed, label the oldest unit as one and continue up your list. These are the numbers to be used in the equations. It's pretty straightforward but I have thrown in a twist or two! Expect to do some research!
Final Coordinates
North 52 [Int2-Till1+ST4][ST3].[LS1+SS2][ST2][Soil1-SS1]
West 106 [Int1-LS4][SS3+Cg1+ST4].[Till1-SS6][ST1][LS5]
Have Fun!!!!
