Tucked inside Dorset Mountain is the world’s largest underground marble quarry, spanning an area of about 16 football fields and stretching for over a mile – all underground. There’s one entrance to the Vermont Danby quarry, and it’s the same one that’s been in use for over 100 years.
Colorado Marble is prized for the stone’s pure color, pure composition (99.56% calcium carbonate), light veining, and consistency of the pattern throughout the formation. These attributes and beauty – in addition to the sheer quantity of stone present – give Colorado marble a place of prominence in the world market.
The story of Rocky Mountain Quartzite is a classic American success story that brings together all the necessary elements: favorable geology, a product that could distinguish itself from others, and a business plan and workforce that could develop the company to its full potential.
Every block of stone holds a story. Not just in its geologic past, but also in the ways that stone becomes part of human history. Behind every successful quarry is a collaboration between the forces of nature that created the stone, and human inventiveness that built it into a successful venture.
