Just over 160 years ago, a physician, geologist, paleontologist and hipster-beard progenitor by the name of Dr John Strong Newberry, a member of the San Juan Exploring Expedition led by Captain John N. Macomb, jotted down the following:
“The Mesa Verde is, geologically, but a portion of the high table-lands which border the Upper San Juan; the northern margin of which is followed by our route from the ford of the Chama to the Mancos.”
This rather dry sentence isn't particularly notable, other than the fact that it contains the first official recorded use of the Hispanic name "Mesa Verde", though the way in which Newberry writes implies that the term had been in common use for some time.
As is often the case with human endeavours, the San Juan Exploring Expedition was tilted toward the military and political, rather than the more pure enterprise of simple exploration, its primary intention being to discover a path to move military equipment west from Santa Fé, New Mexico to Utah, and while doing so map unknown portions of the geography of the western United States.
As we all know, Mesa Verde means "I'm awfully hot waiter, could I trouble you for a sugar-free sparkling ginger ale with a sprig of mint and a little lemon twist?" or, more commonly and less hydrationy, "Green Table", due to the area thus named being generally verdant and, to a large extent, relatively flat.
