Dateline – Near Salida and Cañon City, Colorado. It seems counterintuitive, a misnomer. The Arkansas River heads in the high country of southern Colorado, and a portion of northern New Mexico. It’s the fourth longest river in the United States, obviously named for an encounter in its namesake state. But it seems like it ought to be called something else, like the “Rio Truchas” or “Boulder River” or “Pike’s River.” Its moniker doesn’t fit, here at least. Zebulon Pike passed through here under Jefferson’s watch in his zealous attempt at exploring the then-northern Spanish colony. Pike got arrested for his endeavor, and in the complex outcome, was paroled in Mexico. For it all, he got a peak named after him; its waters feed the Arkansas.
