GCTPEX Insidious VI - Hidden Secrets (Multi-cache) in Massachusetts, United States created by emmett

This cache has been archived.

emmett: It is time to finish with archiving my caches. I understand some may be interested in completing this series. The containers are still out there as far as I know so you can still log finds but I will not be doing any maintenance. I don’t want them listed on GC.com any longer and will not be working on any of them unless and until I have the time to modify and publish these as new caches on another site.

Geocache Description:

The Insidious series has been created to provide a variety of tough tests, especially suited for those who prefer more of a challenge. For those not inclined to tackle this series at maximum difficulty, an alternate, easier means of conquering the Insidious collection is available by acquiring the "hidden secrets" available at the posted coordinates.

Hidden Secrets

The “hidden secrets” of the Insidious Series are revealed on a clue sheet provided at stage one of this cache. The sheet has fourteen pictures of sites from the first four Insidious caches, including parking areas and all subsequent micros and stages for Insidious I, II, III, and IV, except Red Herrings.

Those who have struggled at another Insidious cache, or those who have not attempted any, may now use these pictures to help find micros and caches that might otherwise have been quite difficult to spot. The pictures won't necessarily guarantee success, but they will dramatically reduce the risk of failure.

If you visit stage one merely to grab the "hidden secrets" for help in finding other Insidious caches, please post a note on this page to document your visit and mention your use of the "hidden secrets" when posting logs for the other I-caches.

About this hunt

This is the final cache of the Insidious series. Unlike the other hunts in this series, all the hides are pretty straightforward. The difficulty rating has been set at 4.0 only because this hunt requires knowledge that must be obtained by first completing other Insidious caches.

It’s a four stage multi located in Wittenborg Woods, a Framingham Conservation land that abuts Sudbury Conservation land and property owned by the Sudbury Valley Trustees. Parking is on Wayside Inn Road in Framingham near the Sudbury line.

The trail system here connects to Nobscott Mountain to the east, home of several other caches. The Wittenborg Woods and associated trails also connect to Henry Hill to the west, home of another cache. For a trail map of Wittenborg Woods and other nearby areas, visit the Sudbury Valley Trustees web site (visit link)

The posted coordinates above are for stage one where you will be searching for a small container, less than ten feet from the trail, with "hidden secrets" clue sheets inside. The fourteen pictures if Insidious sites have been ordered randomly and each has been given a value at the top left corner. Your task is to determine the correct order and then assign a letter for each picture in proper order, “a” thru “n,” beginning with the parking area for Insidious I (“a”) and ending with the final cache location of Insidious IV (“n”).

Next, you must assign the value at the top corner of the picture to the corresponding letter. For example, if the number at the top left corner of the picture of the Mount Ward Kiosk (parking for Insidious I) is 15, then a = 15. If the number at the top of the picture of the Insidious IV final cache is 40, then n = 40. You will then use these values to complete the equation below.

Stage two is located at N 42 20.xxx, W 71 27.yyy

xxx = a + c + e + g + i + k + m + o
yyy = b + d + f + h + j + l + n + p

o = 501, p = 248

At stage two, you will find the coords for stage three, and at stage three, you will find the coords for the final cache. All stages are very close to the trails. No bushwacking is needed. Total round trip is about two miles.

After you find stage three, you may be tempted to backtrack. Your best option is to continue on the trail in the same direction. It will eventually make a sharp turn towards stage four.

Caution: The micros at Insidious I and Insidious IV were specifically numbered. When completing the stage one task for this cache, make sure you order the pictures of those micro locations in accordance with the actual cache page instructions, which may or may not be the order in which you found them. As of October 20, 2008, micro number one at Insidious IV is no longer in play but the Hidden Secrets clue sheet still contains a picture of that spot. To allow cachers to identify and sort the pictures properly, a description of the original micro one location has been placed inside one of the Insidious IV Red Herring containers.
