WHY UNDR

No expert required. Ten minutes, your own mailbox, nobody on your property.

See your ground’s stats. How it drains, how it leans, what grows well in it.

Unearth value. Gold, silver, platinum and the rare earths.

Private and confidential. We never sell your results.

Learn your land, and how to care for it. What it’s made of, how it behaves, what it responds to.

A report you’ll want to share. Plain English, your land’s type, real comparisons.

Two things show up in the mail.

An open UNDR kit with the shovel, gloves, pouches and prepaid mailer laid out
First—the kit

Shovel, gloves, sterile pouches, prepaid mailer. Dig, seal, drop it in your own mailbox.

An UNDR report open on a laptop
Then—the report

Your scoop, element by element, in plain English. Posts to your account days after your sample lands.

  • 1. Dig

    A small shovel and a card telling you how. Ten minutes. Gloves in the box, and the kids will want a turn.

  • Mail-in soil sample kit with envelope and test vials for home land testing

    2. Mail

    Seal the pouch, and drop it in the prepaid envelope.

  • 3. Find out

    Receive your report and analysis in your UNDR account portal.

Everything about your place has been looked at. Except the land.

The inspector checked the roof and the wiring. The county knows your lot line to the inch. Nobody was ever asked to look at the dirt, so the biggest thing you own is the part you know nothing about.

What we go looking for
Precious metals
Rare earth elements
Oil
Heavy metal toxins
Petroleum contaminants
45 standard elements

Six categories of things we can look for. Your kit decides which of them get run, and the report says plainly what showed up and what didn’t.

The report

This is what comes back.

Not a lab printout. Real pages from real reports:

Your short answer

Two of ten heavy metals showed up, both under the common range. Your land reads Volcanic, and your iron is in the range of samples from Iceland.

One plain paragraph at the top, before any chart.

Real numbers from a Treasure Hunting report. Over 400 times above normal.

Your land's type An UNDR report naming the sample's land type and where that type is found

A map of where else on earth the ground runs the same way, and the U.S. survey sites closest to yours.

The fingerprint An UNDR report plotting every element against the typical range

Everything screened, on one chart, against the national range.

Famous comparisons An UNDR report comparing a sample's readings to well-known regions

Readings in every report get lined up against somewhere you've heard of.

Carson and Mari, founders of UNDR
Why this exists

We built the lab because we couldn't get the answer either.

We're Carson and Mari. We got curious about the land under our own house and found that knowing took either a lot of money or a job in the industry, so we built the lab.

Every sample is run here in the U.S., on the same instrument with the same protocol, and a person reads every report before it goes out.

"What if it comes back boring?"

Every one comes back with a type, a map, two famous comparisons and a page per element. If yours tells you nothing you didn't already know, email us and we'll refund it.

"What if it comes back high?"

Then you'll know. An elevated number comes with a name, the usual reasons it shows up, and who handles it. A number you never looked up gets none of that.

Pick your kit.

Every kit ships with the shovel, gloves, pouches, prepaid mailer and the full report.

FREQUENTLY ASKED QUESTIONS

Is this really like 23andMe?

In the way that matters: you mail in a sample, a lab runs it, and you get a report you'll read more than once. We're not connected to them. We just thought the land deserved the same treatment.

Which spot should I test?

The one you're most curious about, or the one the kids use most. Premium and Plus kits take two samples, and you can always send another.

Does it have to be my land?

Your yard, your parents' place, family land, or anywhere you have permission to dig.

How accurate is it?

Accurate for the sample you send. Lab-grade instruments, recognized methods, and every number shows its own detection limit and margin of error. One scoop doesn't describe a whole property.

When will I get my results?

Three to five business days after your sample reaches the lab, 1-2 on Premium. We post it to your account and email you.

What happens to my information?

We never sell your results.

Can I give it as a gift?

Yes. Pick the gift option at checkout and we'll take it from there.

You’ve walked over it a thousand times.

One scoop, our own lab, and a report that tells you what’s actually down there. Kits from $99.

Some people wonder. Some people find out.
