Distribution
While the species presently has a broad range across the western part of North America, its distribution in the early Holocene era is known to have been a different one. From pollen core data, a portion of the prehistoric distribution of this species has been mapped; for example in the Late Wisconsin period, Escobaria vivipara occurred in the Waterman Mountains (Coconino County) of northern Arizona, (the Waterman Mountains are in SE Arizona), although the species does not occur in this location in the present time.

“My topic for Army reunions ... this summer: How to prepare for war in time of peace. Not by fortifications, by navies, or by standing armies. But by policies which will add to the happiness and the comfort of all our people and which will tend to the distribution of intelligence [and] wealth equally among all. Our strength is a contented and intelligent community.”
—Rutherford Birchard Hayes (1822–1893)
