Uncovering Hidden Fossils on the Grand Canyon's South Rim

As you stand at the edge of one of the world's most iconic natural wonders, the Grand Canyon, you're not just gazing upon a breathtaking expanse of red rock – you're also witnessing the remnants of a 270-million-year-old sea floor. The Coconino Sandstone, exposed in the Grand Canyon's South Rim, holds secrets of an ancient past, waiting to be uncovered by curious explorers.

Geology 101: What is Coconino Sandstone?

Coconino Sandstone is a type of sandstone formed from the remains of ancient sea creatures, including coral, shellfish, and even dinosaur tracks. The sandstone's distinctive red color is due to iron oxide present in the minerals. At the Grand Canyon, the Coconino Sandstone lies above the Toroweap Formation and below the Hermit Formation.

Where to Look for Fossils

To find fossils in the Coconino Sandstone, head to the following locations:

• Desert View Point: A scenic overlook with stunning views of the Colorado River. Look for exposed rock faces and take a closer look at the sandstone's surface.
• Grand Canyon Village: Explore the village's many trails, including the Bright Angel Trail, which passes through areas with Coconino Sandstone outcroppings.
• Yavapai Point: A viewpoint that offers panoramic views of the Grand Canyon. Take a short walk to explore the surrounding rock formations.

Tips for Fossil Hunting

• Bring binoculars and a hand lens or magnifying glass to examine small details on exposed rock faces.
• Wear comfortable hiking shoes and bring plenty of water, as fossil hunting can be physically demanding.
• Consider joining a guided tour or seeking advice from park rangers to increase your chances of finding fossils.

What to Expect

As you search for fossils, keep in mind that the Coconino Sandstone is an extensive layer, spanning millions of years. Finding fossils will require patience and persistence. Be prepared to spend hours scanning rock faces, and don't be discouraged if you don't find anything immediately.
