I am trying to solve this Puzzle based Geocache.

It is simply this string on dots and dashes

--.-..-....-.---...--.--.---..-..--..-..---.--.--..--..--.---..-..---.-..--..-..--..---.-..---..--.--..-.---..---.--.---.--.--..--..---.-...--.-..---..--.--.--..--..--..-.---..--.---..-..-..--..---.-..---.--..--..-..---.---..-.--..---.--..-..--...---.-.--

Initially I thought it might be Morse code, however I'm not sure as there is no way to determine where the spaces are. I've been unable to find something that is this close to morse code.

There is one hint with is:

Fence not ladder

The answer to this puzzle should be a set of GPS coordinates. (Most likely is this format: N 54° 58.300' W 001° 35.075')

    $\begingroup$ Doesn't look like true Morse code because there are many more - dashes (140) than . dots (115). If I remember, Morse was devised to use slightly more dots than dashes because dots take less time. $\endgroup$

    $\begingroup$ @humn: That presumable assumes standard english words/sentences. I believe that there are 14 morse letters that have equal or more dashes than dots and you could probably easily form some kind of coded message that uses the majority those. Likewise numbers have an equal spread of dashes and dots so something numeric could easily not have a typical spread (though the strucure here doesn't lend itself to being lots of digits). $\endgroup$

    $\begingroup$ Well, I went and solved it. It's not Morse code. The hint actually was helpful, as was the "related web page". However, as a fellow geocacher, I really don't feel like spoiling the solution here. That just seems to go against the etiquette, and probably against the wishes of the cache owner. Mystery caches aren't supposed to be that easily solvable by googling. (In fact, given that it's a premium cache, even just posting the encoded coordinates here in your question might be considered kind of bad form. After all, presumably the CO had some reason to make it premium in the first place.) $\endgroup$ Sep 12, 2017 at 20:57

    $\begingroup$ Hmm. A hint would certainly seem more reasonable, but I'm not sure what I more I could say than I already did without spoiling the solution outright. Once you figure out what the code actually is, the solution is really quite trivial. (I suppose that kind of counts as a minor hint in itself.) $\endgroup$ Sep 12, 2017 at 21:40

    $\begingroup$ FWIW, I posted a question about the appropriateness of geocaching puzzles here on the meta site. Feel free to chime in there if you want. $\endgroup$ Sep 13, 2017 at 0:44

I am new to this and have less than 50 rep, that's why I am leaving a comment as an answer. I'm sorry.

This could be binary. dash = 1, dot = 0. Also, it is exactly 255 characters long.

    $\begingroup$ Good spot! Welcome to PSE. I'd say this is the beginning of an answer: if you convert the code into binary, and from there convert it into ASCII using an online interpreter, then this would be a fully-fledged answer. It may not necessarily be the correct answer, but it would be a good attempt. $\endgroup$

  • $\begingroup$ Hey @Vuudi, thanks for your answer. It's a good one but wouldn't the fact that 8 doesn't go into 255 stop it from being binary? $\endgroup$
