Amos, you do not understand potatoes. Like most, you think of them as tubers growing on the roots of plants.

NOTHING COULD BE FURTHER FROM THE TRUTH!!!

Potatoes are tiny, blind creatures similar to nemotodes which crawl underground searching for a plant's root system upon which to "suckle." The very best plant for this are the various varieties of Solanum tuberosum (or "Tubas of [St. Francis] Solanus" -- the reason for this name is irrelevant here). Potatoes can sense these plants many miles away and will literally bore through mountains to get to them. Once there, they attach themselves to the plant's roots so firmly that the plant literally grows around them and the potato loses it's own identity into that of the plant.

Once, Idaho (for example) was a high, flat plateau stretching from Montana to the Oregon and Washington borders. Early settlers planted
Solanum tuberosum (the original settlers lived on camas roots) and attracted the potatoes. This mass migration of potatoes from one place to another caused the soil and rock to collapse, as a sinkhole does when the water below is pumped out. This gave birth to Idaho's mountains. The same happened in Maine and Ireland, where the collapse of the land formed the immense central plain -- were it not for the potato Dublin would be an alpine resort.
