Details
“Soft, creamy sand-like crunch with a whisper of petrol on the finish.”
Yellowstone is a rare, hand-foraged Montana clay from Taste Montana, collected personally by forager Samantha Hokulani from the rugged terrain around Yellowstone National Park. Sold in irregular, hand-broken mustard-yellow chunks, it offers a soft, slightly sandy, non-gritty texture with a medium crunch and a genuinely distinctive flavour — grounding muddy topsoil and petrichor, with some pieces carrying a faint, true-to-geology whisper of gas or oil.

Good to Know
- Comes in a reusable plastic container rather than plastic-free packaging — source copy notes this is a deliberate exception to Earthy Crunch UK's usual no-single-use-plastics approach, needed to keep this product damp.
- Best kept slightly damp in an airtight container; a few drops of water will restore moisture if it dries out.
- Source description calls this "a rare and limited find, never before stocked in the UK" — availability may be limited.
Safety & Disclaimer
Earthy Crunch UK sells natural clay and chalk for sensory, hobby, collecting and ASMR use. These products aren’t sold as food, food supplements or health products, and they’re not food-grade certified. Under UK rules I can’t market them as food or encourage eating or swallowing them.
I recognise and respect that for some people in the pica and geophagy communities, tasting, crunching, chewing, spitting or swallowing clay and chalk is an important part of their personal experience. I don’t dismiss or judge that. But I can’t guarantee any product is suitable to eat, and I don’t make claims about its safety for consumption or any health benefits.
Sourcing matters just as much. Research sellers carefully, think about where products actually come from, and look for clear information on composition and any testing. Be wary of sending money to unknown or unverified sellers you’ve come across in Facebook groups or other online communities without doing your own checks first. A seller being popular, or recommended by another customer, doesn’t on its own mean a product is safe. For what it’s worth, everything here goes through a proper checkout with secure payment, and my reviews are public. I’d want the same from anyone I bought from.
Where testing information is available, read it and understand its limits. Testing is useful, but it doesn’t automatically mean a product is suitable to swallow, and Earthy Crunch UK can’t certify any product as safe to ingest. If you choose to taste or swallow anything, you do so entirely at your own discretion and risk.
If you’re pregnant, breastfeeding or getting strong cravings for clay, chalk or ice, speak to your GP. Cravings like these can be linked to things like low iron, and it’s worth ruling out. Adults only. Keep away from children and pets.
Products are repackaged in the UK in a clean home environment.

To keep your clays and treats fresh, crunchy, and full of flavour, always store them in an airtight container in a cool, dry place away from moisture, humidity, and strong odours. Exposure to air or dampness can alter both texture and taste.
We highly recommend using our stash boxes, available on the website — designed specifically to protect and organise your clay collection with ease.
