How Geocaching Works

Please note Use of services is subject to the terms and conditions in our disclaimer.

Geocache Description:

This cache is intended to show you some interesting local historical structures, to test your skills on the use of your GPS unit, and to take you to a location you might otherwise not visit. The cache is a combination of a three part virtual cache plus a physical micro-cache. All virtual parts are optional.

The cache location is on public land open for various public activities. While the location is easily accessible by well-traveled local roads, it may take a little bit of work to actually find the only route to the cache.

All three parts of the virtual cache are done from the same location, which is also the location of the physical cache. Please bring your own pen to sign the logbook. Please return the micro-cache container to the same exact location as where you found it. Some stealth may be required as this is a popular area. No bushwhacking is required. Ample free parking is available. No long walks either. Enjoy seeing the other interesting activities and views from this cache location!

Proceed to the initial co-ordinates above to start Part 1 of the three-part virtual cache and to find the physical cache. Binoculars are helpful for Part 2, but not required. Binoculars are required for the optional Part 3. A telescope works well too.

Virtual Part 1:

To see the two cache structures, look from the initial cache co-ordinates above towards a bearing of 215 degrees. The structures are .16 miles away. You can get to within 270 to 300 feet of the structures on public land. The structures are on private property so please honor the “no trespassing” signs.

This is a good opportunity to test your skills on the use of your GPS unit by using bearings and distances to find the target when co-ordinates are not given.

Virtual Part 2:

Set your GPS to the following co-ordinates:

N44 DEG. 33.516 MIN.
W87 DEG. 59.653 MIN.

From the location of the initial cache co-ordinates, look towards the new co-ordinates. You should see a small island. This is the original location of the two cache structures.

Virtual Part 3: (Optional)

Binoculars are required for Part 3. While standing at the initial cache co-ordinates, reset your GPS to the following co-ordinates:

N44 DEG. 35.782 MIN.
W87 DEG. 59.048 MIN.

Look for a manmade structure on this long wooded peninsula. This structure is approximately 2.7 miles beyond the island you located in Part 2. This one can be tough to see even with binoculars. A clear day with good visibility is required. The structure is almost as tall as the majority of the trees on the peninsula. It is located centered between the white channel marker on the left and the green channel marker on the right. Enjoy the challenge!

To get credit for finding this cache, you must find the physical cache. Virtual Parts 1, 2, and 3 are optional. Please do not post the answers to the questions in your logs. E-Mail the cache owner by selecting the owner profile and send your answers to the following questions:


Virtual Part 1:

What is the long horizontal structure you are standing next to at the initial cache co-ordinates?

What are the two cache structures?

Virtual Part 2:

What is the bearing of the island in Part 2 as viewed from the initial cache co-ordinates?

Virtual Part 3 (Optional):

Is the old structure to the left or to the right of the island you located in Part 2 as viewed from the initial cache co-ordinates?

What do you think this old structure was?

What material is it made of?

Cachers who submit answers to the questions will receive a reply with additional history and some historic photos. For those who would like copies of the historic photos along with their virtual reply, please send another E-Mail address as the address will not allow me to attach photos.
