“The Petrified Forest of Arizona” by E.A. J. Seddon, Associate Editor, Southern Division in The Mountain States Monitor, September 1918.

The Petrified Forest of Arizona is an area covered with the fossil remains of prehistoric trees. The name “Petrified Forest” is somewhat of a misnomer: the word “forest” suggests standing trees, but these trees fell over long ago and have been preserved in stone. At one time, they formed part of a forest of gigantic trees. They proudly reared their heads above the surrounding country, but they were conquered and laid low by some force of nature.

Then began the process of embalming and preserving these fallen monarchs. They were buried thousands of feet beneath the bottom of an inland sea. This was a vast pickling vat where the wood was slowly converted into living gems. We can tell this because volcanic cones and mineral springs still exist in the area. 

Water containing minerals slowly forced its way into the trunks and limbs and roots of the fallen monarchs under a terrific pressure. Eventually, the woody material was gradually replaced by silica, a type of rock. Iron oxides were present in the silica. These oxides created brilliant and beautiful brown, yellow, and red colors in the rock. 

Eventually, the sediment containing the petrified trees was thrown up from nature’s subterranean chemical laboratory. The wrappings of the dead monarchs were slowly washed away by erosion and corrosion. Then the glorious sun shone upon the trees once again. They were no longer rulers of the kingdom of flora, but preserved for all time as agate, jasper, opal, and other forms of silica.

Every day it seems, new inventions surface that promise to add value to our day-to-day lives. But did you know, many of the inventions we interact with on a daily basis were developed completely by accident?

Take the microwave, for instance. This accidental invention was developed by engineer Percy Spencer who, upon experimenting with a microwave-emitting magnetron, found that the candy bar in his pocket had begun to melt. Spencer was then able to harness this radiation into the microwave we use today to make snack time a speedy process!

Perhaps one of the most well-known accidental inventions of today, the potato chip was born when a customer kept requesting that his french fries be sliced thinner and made crispier. Though chef George Crum responded with the chips as a joke, they quickly became a favorite snack around the world!

Even the match is a result of accidental invention. When pharmacist John Walker was stirring chemicals, he noticed that the end of his stirring stick had dried into a hardened lump. When attempting to scrape the dried residue off, a flame sparked, and so did Walker’s idea to turn this accident into a helpful tool!

So, the next time your science experiment doesn’t go as planned, or you burn what you have cooked on the stove, keep in mind that some of today’s most valued inventions were discovered when the inventor least expected it!
