Theo "Ted" Orchard, the man who built Idaho Travertine, passed away August 10 at 91.

Ted joined Idaho Travertine in 1969 leading production, eventually owning the company for decades.

His work included the Idaho Supreme Court building, the Nauvoo Illinois Temple, the Salt Lake City Conference Center, and many other buildings across the country. As a devoted member of The Church of Jesus Christ of Latter-day Saints, he took special pride in the temples and church buildings he helped build.

He especially loved doing the work alongside family, a legacy that continues at Yellowstone Rock today.

His dedication, counsel, and example will be missed.

Continental Buff Cross-Cut on an Oregon estate pool deck.

This project uses a custom black fill color to blend with other stones on site and change the overall aesthetic of the stone. The customization of our stone through fill color makes it unique among other American stones.

Today's the day. Our Virtual Quarry Tour starts at 9:00 AM MST.

In the hour presentation you'll see the quarries, hear the geology behind the stone, and get technical and design perspectives from stone professionals. If you work with natural stone or specify it, this is worth your time.

We're honored to be featured by the Natural Stone Institute's Quarry Advocacy Group this week. Join us for a one-hour virtual tour of our Idaho quarry and production — Thursday, April 23, 11:00 AM to 12:00 PM ET.

The Quarry Advocacy Group, powered by the Natural Stone Institute, is hosting a Virtual Quarry Tour: Yellowstone Rock on Thursday, April 23, 2026 (11:00 AM–12:00 PM ET) and Women in Stone invites you to join us!

This one-hour virtual experience offers a rare look inside an active quarry, exploring the story, science, and design potential behind natural stone. It’s a great opportunity to deepen your knowledge, connect with the material at its source, and engage with the broader stone community.

We encourage all women in the industry (and those looking to get involved!) to attend, learn, and be part of the conversation shaping the future of natural stone.

60 years of American travertine. Same stone. Same source. Same standard of craft.

What started in 1966 and became Idaho Travertine is still quarrying and fabricating domestic stone today as Yellowstone Rock, from the same volcanic region in Idaho and Montana.

We're proud of where we came from and we're just getting started.

We are grateful to Stone World for sharing our story. 60 years of American-quarried travertine, from the Greater Yellowstone region to projects across the country. The full feature is linked in their post. Give it a read.

Twenty-six years ago today, the Conference Center of The Church of Jesus Christ of Latter-day Saints opened its doors in Salt Lake City. Our team, then known as Idaho Travertine, quarried and fabricated over 300,000 square feet of granite to clad the exterior of one of the largest auditoriums ever built.

The Church required stone to match the same granite used to build the adjacent Salt Lake Temple more than a century earlier. The quarry permit was contested. The extraction window was seasonal. The deadline was fixed.

We delivered 300,000 square feet of finished stone in under 24 months. Domestic sourcing and in-house fabrication made it possible then. It is still how we work today.

Doing what others would deem impossible is the legacy we are built on and the standard we still work to match.

AT&T's Whitacre Tower in downtown Dallas has been clad in our Continental Buff Travertine since it was built in 1984. When it needed restoration 40 years later, our stone matched seamlessly.

The restoration covered 320,000 sq ft of exterior stone on the primary tower. Replacement panels were cut directly from field measurements using the same stone from our quarry in Southeast Idaho.

It's a great example of why domestic, American-quarried travertine matters. When you need to match stone decades later, you need a consistent quarry that's still here.

Great work by Dee Brown, Inc. on the restoration!
