Missing Rock Record on Vancouver Island Episode 1

Much of Vancouver Island is covered by a layer of 230-million-year-old basalt, but erosion at select beaches has exposed layers of both older and younger rock that tell a story of continental collision and massive gaps in the rock record.

The Mysterious Folded Limestone of Quadra Island Episode 2

On the hard-to-reach Quadra Island is a small bay with a mass of swirling rock that appears almost liquid.

A Five-Mile-Deep Sandstone Bed in Leavenworth Episode 3

Three Generations of Volcanoes at Mount Rainier Episode 5

The Naches Peak Loop trail is popular for its views of Mount Rainier, but there are more volcanic stories to be found if you know where to look. Rocks just off the trail leave clues to a large volcano out in the Pacific Ocean, and to a newer volcano that sent dikes of magma up through the ancient ocean rock – all before Mount Rainier started to grow.

The Hidden Green Rocks of the Teanaway Episode 7

The granite of Mount Stuart dominates the skyline outside of Cle Elum, Washington, but a unique green rock can also be found all along the trails of the Teanaway. The green look of the Bean Peak serpentinite tells a deep ocean story, but did it combine with Mount Stuart here in Washington or way out in the ocean?

Slate Peak: The Highest Road in Washington State Episode 8

The road out of Mazama, Washington eventually leads all the way up to Slate Peak and the highest road in Washington at 7,440 feet. Scattered around this perch in the Cascades are signs that the rocks that now sit more than a mile up were once down at sea level. Fossilized snails and ancient mud tell a story of our distant past and the region’s landscape during the time of the dinosaurs.
