The company

Volcanic ground, worked by one family.

Our pumice fell from the sky more than 7,000 years ago, when Mount Mazama erupted over what is now Crater Lake.

Beaver Pumice is a family-owned operation in Oregon's interior, mining 100% natural airfall pumice from that same deposit. The combination of a high-purity resource and a modern processing facility lets us produce a wide range of mineral products with consistent quality in every gradation.

An onsite testing laboratory means we can customize products to a customer's needs without ever compromising the standard of what leaves the mine.

Applications

A volcanic mineral that earns its keep across industries.

Lightweight, porous, and hard: the physical properties of pumice make it useful far beyond the quarry.

All applications

Pumice used in construction: lightweight concrete and block Pumice filter beds treating water at an industrial facility Pumice in horticulture: soil conditioning and drainage A natural pumice stone held in hand, used for personal care

Origin

From Mount Mazama to the mine gate.

Every ton we ship began as airfall from one of the largest volcanic events in North American history.

  1. 7,000+ years ago

    Mount Mazama erupts

    A catastrophic eruption in Oregon's southern Cascades throws enormous volumes of pumice into the sky. The mountain's collapse leaves the caldera that holds Crater Lake today.

  2. The airfall

    Pumice settles across the region

    Airborne pumice falls back to earth and blankets the surrounding landscape, building deep, remarkably clean deposits, laid down by air rather than crushed from rock.

  3. The deposit

    A high-purity resource near Crater Lake

    Beaver Pumice works one of these airfall deposits near Chemult, Oregon. Because the material fell as it is, it needs nothing added. What we mine is 100% natural pumice.

  4. Today

    Mined, milled, tested, shipped

    A modern processing facility and onsite testing laboratory turn the raw deposit into consistent, specified gradations for industries across the country.

Operations

Consistency you can spec against.

The quality of a pumice product is decided twice — once by the deposit, and once by the people processing it. We hold both ends.

  • Modern processing facility producing a variety of mineral products
  • Consistent quality across every gradation in the line
  • Onsite testing laboratory for verification and custom work
  • Products customized to customer requirements without compromising standards
80+years of combined material-processing experience
