Tethered to the frozen Mackenzie River, these small water clocks or “clepsydras” were once fluid. However, at minus thirty degrees Celsius, the duration they attempted to measure became interrupted, leaving the clocks frozen in place and time. The installations were created utilizing a Canada Water Survey team’s drilled holes and sticks, after the surveyors recorded the river’s depth, current velocity, and ice thickness at each location.
Sincere thanks to the hydrometric supervisor, Canada Water Survey, Fort Simpson.
