If you're trying to excavate something that you believe is buried deep underground, you may want to contact a company that offers core drilling. With core drilling, you can pull up a sample of earth from the ground and analyse what exists at each level. That can help you hone in on where to dig.
This type of drilling is showcased in the documentary Atari: Game Over. This documentary explores one person's quest to find a giant cache of buried copies of ET the video game. Although he's digging in the New Mexico desert, there's lots of lessons from this film that you may want to keep in mind as you prepare to hire someone to do core drilling for you.
1. Study Potential Risks in the Area
Before you start excavating, you need to know which potential risks you may face. For instance, the people who wanted to find the old ET video games, looked into the history of the area, and they found out that over 50 years earlier a family in the area had accidentally fed their pigs feed that had been laced with mercury. After severely poisoning the family, the pigs were buried, and there were fears that an excavation could release the toxins. Ideally, you should know what you're getting into before you start digging, but a core sample can help you hone in on risks before you really start moving lots of dirt.
2. Keep the Core Intact
In the documentary, the researchers kept the core intact so they could identify where each sample came from. This is a key benefit of core drilling. When you hire professionals to help you, make sure that they can take the core sample to their labs and look at the whole thing at once. This gives you a virtual map to the underground.
In the case of the people searching for old video games in the documentary, they looked at dates on old wrappers or other types of rubbish in the core sample, and they used those dates to let them know if they needed to dig deeper or look more shallowly.
3. Use Core Drilling for Deep Drilling
In the Atari: Game Over documentary, the researchers wanted to find a video game that was allegedly buried in September 1983, approximately 30 years prior to the excavation. As the cartridges were buried in a landfill, the documentary makers knew that they had to dig through decades worth of potential rubbish. However, they also knew that core drilling was perfect for the job core drilling can go as deep as 10 kilometres in some cases. If you need to find something that you think is deep underground, core drilling can be a great place to start, and it can go extremely deep.
