Beginning in 2026, EarthDate is managed by Switch Energy Alliance and hosted by SEA's founder Dr. Scott W. Tinker. Together, we explore earth systems, natural resources, and their relevance to everyday life, with a focus on clear, accessible science education for broad audiences. EarthDate is written and directed by Emmy-winning filmmaker Harry Lynch, and researched by Lynn Kistler. We search for captivating stories to remind listeners that science can enlighten, educate and entertain.","last_synced_at":null,"page_url":"https://stenobird.com/podcast/earthdate-7713094"},"episode":{"title":"The Great Shrinking Salt Lake","slug":"the-great-shrinking-salt-lake","published_at":"2026-05-12T14:00:00+00:00","page_url":"https://stenobird.com/podcast/earthdate-7713094/the-great-shrinking-salt-lake","show_page_url":"https://stenobird.com/podcast/earthdate-7713094","url":"https://blubrry.com/3957418/153852828/the-great-shrinking-salt-lake/","audio_url":"https://media.blubrry.com/3957418/content.blubrry.com/3957418/EarthDate_S14_E05.mp3","summary":"Utah’s Great Salt Lake may seem like a wasteland, ringed by toxic deposits of mercury and arsenic, and filled with water so salty that only brine shrimp can live in it. However, those shrimp feed 10 million migrating birds. And the lake provides eight thousand jobs and two billion dollars in industry, harvesting salt and other minerals. It’s vital to the region’s ecology and economy. But the lake is in danger. Great Salt Lake is the remnant of Lake Bonneville which, in ancient times, was nearly as big as Lake Michigan. Then, 18,000 years ago, the lake found a drainage path to the Pacific Ocean through the Snake River Valley, and its level fell 400 feet. Fifteen thousand years ago, as glaciers retreated from the region, the climate became drier. The lake became landlocked again and started to evaporate, falling another 600 feet to stabilize at its modern size. But over the past century, its been gradually shrinking. In 2022, it hit a record low. This is due to rising temperatures and drier summers in the region, and, importantly, to lower inflow—as the rivers that feed the lake have been increasingly diverted for agriculture and mining. So, Utah began water conservation measures. Then 2023 saw the most snowfall in 70 years, which may lead to record runoff. Only time will tell if Utah’s people, and weather, can save the Great Salt Lake.","meta_description":"Utah’s Great Salt Lake may seem like a wasteland, ringed by toxic deposits of mercury and arsenic, and filled with water so salty that only brine shrimp c…","key_points":[],"chapters":[],"topics":[],"duration_seconds":120,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/earthdate-7713094/episodes/the-great-shrinking-salt-lake/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/earthdate-7713094/the-great-shrinking-salt-lake.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
