These lumen prints were created by rubbing directly onto a small sand bank in Squamish River, a glacier-fed river which supports multiple species of salmon. Glaciers are disappearing rapidly all around the globe, intensifying risks of landslides and imbalances in freshwater fish habitat. The deep crimson is a result of the unusually warm and dry October afternoon during the salmon spawning season. Pacific salmon cannot tolerate warming rivers and are vulnerable to heat stress and mortality when water temperatures exceed 20 degrees Celsius. Photographs such as these provide a micro-window into the movements and components of our surroundings.

The ecological processes on Mars are just as complex as our own; wind and ice sculpt troughs and dunes in the valleys and mountains, ancient river systems and lava channels remain embedded in the regolith, revealing legacies of energy, fire and water. The Martian imagery was collected under the direction of the University of Arizona's Lunar and Planetary Laboratory by the ongoing HiRISE (High Resolution Imaging Science Experiment) project, whose telescope has been orbiting and photographing Mars since 2006. I selected images I was drawn to directly from the HiRISE catalogue.

Both series document the repercussions of atmospheric breakdown in the landscape. Dendritic patterns and substrate compositions mirror one another in their interplanetary relations, contemplating what is to come.
