Geocaching HQ Admin: The City of Portland has a new [url=https://www.portlandoregon.gov/parks/66338]geocaching policy[/url] for geocaches placed on Portland Parks & Recreation (PP&R) property. The policy is intended to support the growing recreational activity of geocaching while also ensuring it does not negatively impact parks, properties, assets, staff or the public.

PP&R welcomes geocaches in many of its parks and properties. However, the property where this geocache is located is one that does not allow geocaches according to the [url=https://www.portlandoregon.gov/parks/66338]new policy[/url]. (Note: Forest Park is divided into three management units - the northernmost unit between Germantown Road and Newberry does not allow geocaches.)

There are many reasons a park may not allow geocaches, based on the determination of the staff who manage each particular site. These reasons can include that the property’s primary focus is on habitat values, the potential conflicts with other park users, among other factors. Because this geocache is in a park that does not allow them, it been archived. As the geocache owner, you are expected to retrieve the geocache container and any associated physical stages within 2 weeks. After August 27th, your geocache may be removed by parks’ staff or other designated persons.

For questions about this policy, please contact Bryan Aptekar, Portland Parks & Recreation, [url=mailto:Bryan.Aptekar@portlandoregon.gov]bryan.aptekar@portlandoregon.gov[/url].

Geocache Description:

The cache is not at the above listed coordinates.

This puzzle was inspired by a similarly-themed puzzle in AZ (The Wheel Cipher, by Wily Javelina), and some coincidental research I’d been doing recently regarding early colonial encryption techniques. It seemed appropriate to launch it during the Presidents' Day weekend.

Jefferson, the principal author of the Declaration of Independence, was the third US president. During his tenure, he doubled the size of the US through the Lousiana Purchase and chartered the Lewis and Clark expedition. Thomas Jefferson is also credited with the invention of the Wheel Cipher for encrypting communications, to keep his correspondence with Madison and a select few others secret from the British.

An example of a wheel cipher is shown below. It is a series of wheels, each with a randomized alphabet, on a single screw.

Cypher Wheel

To code a message, you would take the first letter, find it on wheel one, and write the corresponding letter on wheel two. You would then take the second letter of the message, find it on wheel two, and write the corresponding letter on wheel three. Once you hit the end of the wheel (eg – after letter 23 for a 24-wheel cipher, like the one above), you start again with wheels one and two. Essentially, this becomes an interlacing of 23 individual substitution ciphers. For short messages in those times, it would have been a near-impossible task to crack the code without the key, especially if the author had played with spacing and punctuation.

In the example below, we have a 5-wheel cipher and an unrandomized alphabet (which essentially turns this into a derivative of a Vigenere Cipher with a 4-letter key). With the wheels set with the keyword "Cache", the phrase “First to Find” becomes “Dkwpr vt Cgpi”.

Sample Wheel

Thomas Jefferson also founded the University of Virginia, the first fully secular university in America, which included education in scientific subjects not available at religious institutions at the time. He frequented the campus and was fond of meeting and dining with both faculty and notable students. Not long ago, during some preservation work on one of the original dorms (which housed one of the more famous of the early UV students), the following message was found behind some masonry along with a broken 9-wheel cipher. Fortunately for us, the orders of the letters on the wheels were all in alphabetical order (no randomizations) and it appears that the punctuation and spacing were unaltered. The message reads as follows:

PS vvtw, cnf gqi lakpjvi hwru? “Sf pqzs cjatm vfjcjo uw ds jwfaoqcpah inbvvss ka kvz Eftjvks.” Tkyt rv? Xfv fwsw’v. Df zcbinf wcwwh vxxasvosccch tmeiajtetu.

Can you decrypt the message and find a secret stash Jefferson might have ordered to be hidden in Oregon?

The cache is initially loaded with items relating to America and great American principles – including a copy of the Federalist Papers, the release of a United We Cache geocoin, and the book “How to Talk Your Way out of a Traffic Ticket.” Also contains the First finder spoon of happiness and success.
