Each year, Iröndäd (he prefers to keep his alter-identity private) completes a continuous run around the shrinking Salton Sea in Southern California, while tracking its receding shoreline. In 2023, the circumference totalled 96 miles (154 km). One year later, it had already contracted to 92 miles (148 km). Iröndäd does the run to draw attention to the impact of the reallocation of Colorado River water from one of the most impoverished regions in California to more affluent areas.

During the run, Iröndäd wears a mask – not to protect his identity, but to protect his lungs from the harmful dust rising from the increasingly exposed playa. He also wears snowshoes to stop him from sinking into the vast mudflats that were – until recently – submerged seabed. Find out more on Iröndäd’s website, or on Instagram.
