Exactly where the Corps of Discovery was when William Clark took men to a beaver dam that day no one really knows. Historians guess the place was once somewhere above Macy, Nebraska; but wherever it was, it isn’t. Too bad.
It’s not altogether clear what kind of gear they employed to catch fish. Clark described the technology this way: “the men picked up Some Small willow & Bark [and] we made a Drag.” A seine of some sort, I’m sure, which would have required a couple of the men to drag the ends through the water to thereby trap fish within.
