What is “Big Blue Switch” day and what does it have to do with Geocaching?

On May 2, 2000, just past midnight, the U.S. government discontinued its use of Selective Availability in order to make GPS more responsive to civil and commercial users worldwide. Twenty-four satellites around the globe processed their new orders, and instantly the accuracy of GPS technology improved tenfold. Tens of thousands of GPS receivers around the world had an instant upgrade. Prior to this date, only the military had the ability to receive accurate GPS readings. Now, the entire world can pinpoint precise locations. This is often referred to as the flipping of the “Big Blue Switch”.

On May 3rd, 2000 the first-ever geocache was hidden. (Original Stash Tribute Plaque)  A black five-gallon bucket was placed in the woods by Dave Ulmer. The coordinates were then listed on the internet and the modern-day geocaching was born.  Three days later, the container was located by Mike Teague. Now, twenty years later, geocaching has become a global phenomenon!

We are honored to have been selected to host this event!
