Who Knew?

Then, people remembered Mountain Man Jim Bridger’s tale of the “Two Ocean Pass,” a place on the headwaters of the Yellowstone where creeks crossed the continental divide. Explorers had documented the existence of the pass, but it wasn’t until 1891 that the U.S. Fish Commission sent an ichthyologist to the area.

Mark Miller tells how it's possible for a fish to swim across North America from the Pacific to the Atlantic. Discovered at Twitter via @earthskyscience.

This tiny creek connects the Atlantic and Pacific Oceans. A fish could swim across U.S., from sea to sea! http://t.co/eSvUtIMSpF
