Originally published in 1556, Georgius Agricola's groundbreaking book De Re Metallica remained the leading scientific journal of mining and metallurgy for over two hundred years. It was the first book about mining to be based on field research and observation. The massive tome was also the first to offer detailed illustrations of the various, highly specialized mining techniques, relevant to the period.

Agricola was born March 24th, 1494, arriving on the threshold of the Renaissance. De Re Metallica contains an unprecedented volume of material on alluvial mining, surveying, smelting, alchemy and more, and provides an otherwise unavailable glimpse into the world of medieval mining.

Georgius Agricola passed away on November 23rd, 1555 at the age of 61. Agricola had completed writing De Re Metallica by 1550, but the book did not go to press until 1553. Ironically, Agricola did not live to see his masterful volume published.

In 1912, Herbert Hoover and his wife Lou Henry Hoover translated De Re Metallica from it's original Latin text into English. This new edition was made available only in very limited copies, and was quickly bought up by libraries, historians and book collectors. Long out of print, this rare edition has itself grown in value. In 1950, the book was once again published in hardback, including all 289 of the original woodcut illustrations. These unusual, and highly detailed drawings offer a glimpse into the daily lives of medieval mining communities, and the curious devices they contrived.

Much credit is due Agricola, as his contributions to the sciences of the ages is without precedent. He is credited with advancements in Geology, Mineralogy, Mining Engineering and much more. Agricola was a scientist. He had little use for alchemy, and those who would be alchemists. He explored soil mechanics, tunneling procedures, and even expounded on a simple but profound understanding of potential dangers permeating the ground, and the release of deadly gasses, which he referred to as exhales.

The world has changed dramatically since the first publishing of De Re Metallica, as has the science of mining and metallurgy. Still, Agricola's work remains an irreplaceable scientific journal and indeed, one of a kind. The book is highly recommended to anyone interested in the history of medieval mining. The book can be difficult to find, but don't fret, copies are available. If you have trouble locating one right away, you just may need to do a little digging.

A Guide to Grand Canyon National Park

The magnificent Grand Canyon. There is nothing else quite like it on Earth. Located in northern Arizona, this spectacular geological feature has formed over a period of six million years. Created by a process of ‘uplift’ normally associated with mountain ranges, the scenic views are vast and unforgettable. Layers of ancient rock formations cast striking images, not soon forgotten.


The Grand Canyon

Each year thousands of visitors from around the world come to experience the canyon, and you can too! However, before you start packing there are a few things you may wish to consider. The Grand Canyon is located in an area of high desert, carved by the mighty Colorado River as it winds it's way through portions of the Kaibab, Coconino, and Kanab Plateaus. Stretching nearly three hundred miles, the canyon is home to a bevy of wildlife, and countless recreational opportunities, including hiking, white-water rafting, bird watching, photography, oh and pack mule excursions for the brave of heart.

Designated a national monument in 1908, and a national park in 1919, Grand Canyon National Park remains one of the oldest national parks in America. Access to the canyon is limited, however, with most visitors entering the park from the south rim via Arizona Highway 64 near Tusayan. Park headquarters are located at Grand Canyon Village, a short distance from the park entrance. In all, approximately thirty miles of the south rim are accessible by road. There are no open roads connecting the north and south rim of the canyon.

Although the vistas are stunning, one should keep in mind that most parts of the Grand Canyon are extremely remote and obviously dangerous. When visiting the canyon, be sure to stick to the developed roads and trails. Many remote locations can be reached by backpacking, but be sure you plan your visit wisely.

An annual national parks pass can be purchased at the gate for a fee of $80.00. For some, this pass may not be a wise investment, but for those who simply can’t resist the allure of the outdoors, it is worth every dime.
