HCN prides itself on digging deep, but this month we literally go underground, accompanying Emily Benson into a Wyoming cave, where scientists who study cave formations hope that 100,000-year-old weather data can help us understand climate change. This summer’s flooding damaged property around Yellowstone National Park, but in the long run it might refresh the ecosystem. Despite a recent Supreme Court decision, the Environmental Protection Agency can still shut down polluters. There’s money in restoring landscapes ravaged by extractive industries, while Arizona citizens hope to protect groundwater with the help of a ballot initiative. Have you ever thought the land might be better off under new management — maybe the original management? The LandBack movement has suggestions. On the Navajo Nation, Indigenous farmers like Graham Biyáál are reclaiming traditional growing techniques and preserving seeds and recipes. If Biyáál’s blue cornmeal mush doesn’t fill you up, try visiting California’s Punjabi dhabas. We also review an enchanting new short-story collection and struggle to keep up with Cassie da Costa as she runs her first half marathon.
