Hunt for the Lost Civilization

Codebroken: One of the ammo cans had an error for its own puzzle
Last week I took a long walk in the Assinaboine Forest with a friend & fellow geocacher and found a few hidden stashes. Of the half-dozen we found, most were the normal type – you enter a set of coordinates into your GPS, try to get to the marked location (‘ground zero’) and then find the hidden container.
The last one we attempted was a puzzle cache called Lost Civilization; an older cache that had been transferred to a new ‘owner.’ To get the coordinates, we were supposed to decode a set of dots and dashes provided along with the description… except that after some research, the encoding turned out to be broken.
For anyone interested, the correct code should be:
.. ….| .. || .. ..| 0
…. ..||| ….|| . || |
More information about this puzzle can be found on its cache page; you may need to be logged in to view it.
