Our project for the Summer of 2016 was to create a computerized database for all the minerals in the John Weber Collection. A team of people worked to take the collection which had been managed as a manual system by John and transform it into a searchable electronic database. Thanks to the team of Chuck Ludovissy, Chris Burhart; Jeff Connolly, Jack Malpass, Kara Malpass and Marsha Malpass, the Museum now has a phase one database of 2, 927 minerals that John collected over his lifetime. The minerals are housed in 102 special plastic bins noted in the photo. There are 619 species of minerals with 2,187 coming from the US and of those 1,190 are from the state of Arizona. Australia was well represented with 693 minerals. Every mineral has an identifier, source, description, bin locator, weight, size and photograph, with other details to be added. More of our collection will be added to the databse over time.
Pinal County is booming and it's growth is projected to continue at a rapid rate. Within this mainly rural area are some of the most pristine and available sites for exploration and collecting. Located halfway between Tucson and Phoenix, the quaint City of Coolidge lies waiting for the rock enthusiast. The area is known for the many mines that dot the area and are a magnet for the collector. All we need is YOU!
The Pinal Gem & Mineral Society is resident in the Artisan Village of Coolidge at 351 N. Arizona Blvd in Coolidge, AZ 85128.
Coolidge is also the home of the Casa Grande National Monument and the surrounding desert is a mecca for rockhounding.
The Casa Grande National Monument in Arizona features the Casa Grande, a “Great House” of the Hohokam people that lived in the Gila Valley from approximately 300 CE to 1450 CE. The Casa Grande is one of the largest prehistoric structures ever built in North American and the structure’s purpose remains mysterious despite extensive archaeological excavation. Needless to say, it carries powerful intrigue for the modern-day visitor. Walk around the Casa Grande structure and wander the desert landscape that surrounds the site to expose yourself to the mystery of America’s ancient human history.

Wednesday, December 21, 2016 - Precambrian Geology and Mineral Deposits of Arizona with emphasis on Pinal County by Ray Grant.
The Precambrian is anything older than 541 million years. Two billion years ago there was no Arizona or Pinal County. North America was much smaller and there was only ocean where Arizona is today, and the North American continent ended in Colorado. The continental crust started to form in northern Arizona about two billion years ago and continued to form south across Arizona ending about 1.6 billion years ago in southeastern Arizona. The oldest rock in Pinal County is called the Pinal Schist and it is about 1.7 billion years old. Learn about this old rock and the other Precambrian events in Arizona and Pinal County.
Wednesday, January 18, 2017 - Australia Night at the Museum. Our Museum has an outstanding collection of Australian minerals from the John Weber collection; come and see these specimens. From 5 to 7:30 PM we will have light buffet and refreshments while you look at the Australian collection and talk to Dehne McLaughlin from Tasmania, Australia who supplied most of these specimens. The meeting will start at 7:30 and Dehne will be our speaker.
