Today, a few friends from my running club and I went hiking out west of Banff. We did the Johnston Canyon hike. It consists of two sets of large waterfalls- the Lower and Upper. 6 km to the top of the Johnston valley is the Ink Pots- six clear greenish pools filled with spring water. This water stays roughly 1 deg Celsius all year round. It was an awesome hike and the weather was beautiful. It took ~ 5 hours including a nice long lunch (with wine!).
