Dale Altman and his grandson Josh Doran live on a 5-acre (2-hectare) plot atop a hill on Hawaii's Big Island by the erupting Kilauea volcano, where they grow medical marijuana. They are the last remaining residents on Halekamahina Hill, after two roiling streams of lava spouting from ground fissures and flowing into the sea, completely cut off the community. Altman, 66, estimates they have $100,000 worth of marijuana in the field that they are harvesting. "That's why we didn't leave. It's taken a lot of work." Altman says he doesn't want to evacuate, leaving behind his home and marijuana crop with no income and nowhere to live. And atop the hill, the house is safe from the lava flows and its attendant fires. "We're not stupid. We thought this out," Altman says. I came by boat to this now desolated piece of paradise that drew retirees like Altman and adventurers like his grandson to come live under the shadow of one of the world's most active volcanoes.
