My previous photo ( http://365project.org/schmidt/365/2017-07-11) of geocaching containers was a precursor to this one. We placed 37 caches along the North Saskatchewan, but they were all puzzle caches, which allow you to have a virtual location show up on the site map.
Using virtual locations allows you to arrange them into patterns called "geo-art" - in this case, I arranged them into the shape of a paddle and called the series "North Saskatchewan Power Paddle".
