It's all hands on deck in an effort to save a humble Oregon butterfly, the Oregon Silverspot. We join the Lloyd Brothers, who spent the last 70 years exploring the overlooked giant of the Washington Cascades. Then, we follow scientists in their search for a rare, but beautiful lily in the bogs of southern Oregon. And enjoy a winter dawn at Hosmer Lake.
