Our first cache named "Sky Liquid" was placed at the old water tower in Airdrie, Alberta. You've probably seen it as you drive past Airdrie on the Number 2 highway. We think these old relics are quite interesting and definitely give the towns of Alberta a distinctive look, so we plan on placing a few more at different locations and making "Sky Liquid" a series.
While this is not exactly a "tower" per se, it is still an interesting landmark relating to water storage in Carstairs and fits in with our theme. It is somewhat similar to the tower in Didsbury, but obviously not as tall. Still, we thought it was a pretty cool and unique looking water container for the town of Carstairs.
From the official Carstairs website: "Residents in the Town of Carstairs receive their water from the Anthony Henday Water Treatment Plant at Innisfail, a safe, reliable source of potable water for our citizens. This water treatment plant incorporates state-of-the-art membrane filtration."
You are looking for a non-traditional container which contains a bison tube.
