Geocache Description:

Only available between 7 AM and 11 PM!

Once, long ago, Dublin Avenue Park was host to a quick and easy multi-cache. A gravel trail greeted visitors at the end of the street and wound its way through wooded bottomland. Searching a sycamore tree brought forth a small container with the final location: an ammo can under a log. Since then, much has changed.

Columbia's growing trail system eventually reached the small park utterly altering its appearance. A raised boardwalk was installed to skirt the former terminus at the Columbia Audubon Nature Sanctuary. Cement replaced gravel, and the path was straightened. Those traversing the new trail system can easily pass through the park and never know its origins.

However, if one is adventurous, they can discover bits and pieces of the past! Start from either parking location (Dublin Avenue is closer) and make your way to the coordinates. There, you will discover a fairly new park bench. A small plaque at the center lists a couple of dates. Take note of the oldest year. You'll be using it to find the location of the geocache!

Trail CloudsDo you have the oldest year? Good! Let the year equal ABCD. For example, if the year is 2003, A would equal the first digit, 2, B would equal the second digit, 0, and so on. Take these numbers and substitute them into a couple of easy arithmetic equations.

E = B - C
F = E + A

Now, plug your values into the following coordinates:

N 38° 56.FEB W 092° 23.CDA

It is at this location that you may find the geocache! Be sure to replace the container as it was discovered.

Permission to hide this geocache was graciously provided by Lida Gouchenour of the City of Columbia Parks and Recreation Department.
