Historian and author David Nicandri joins Clay in the LTA Airstream in Olympia, Washington, for a conversation about lingering mysteries of the Lewis and Clark Expedition. The first question was why Meriwether Lewis’ journal remained silent when he finally reached the Pacific Coast, which was the primary purpose of his transcontinental expedition. It was a dereliction of duty for the leader of the expedition to fail to write about reaching the Pacific after 18 months of gruelling travel. Clay and David attempt to make sense of Lewis’ silence. The second mystery they tackled concerns the enduring appeal of the Lewis and Clark story after 230 years. There are several dozen interpretive centers for Lewis and Clark, none for Zebulon Pike, who was exploring the Mississippi River drainage at the same time, and none for John C. Fremont, a generation later. Why? This episode was recorded September 9, 2025.
