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.
Drumheller's water tower is definitely a good size, and hard to miss. Certainly it is much larger than the one in Airdrie, and also of a completely different design. We had to place the cache this distance away as there is another cache in the park right beside the water tower.
You are looking for a non-traditional cache container containing a bison tube.
Obviously there is no shortage of things to do in Drumheller after finding a few caches. Enjoy your visit!
