Imagine going back million years ago when dinosaurs ruled the land and the climate was so warm that the poles were ice-free and reptiles frolicked. Early August, Undergraduate Elli Ronay, graduate student Hehe Jiang and I found ourselves traveling across the desert southwest in search of opals, agates, silicified fossils and volcanic ash. Elli has been characterizing the chemistry and mineralogy of Cretaceous ash beds in west Texas for her senior honors thesis with the hopes of better quantifying the flux of volcanic ash and the extent to which volcanic ash can be dissolved to serve as a biological nutrient. She spent the last year developing the method to perfection and she hopes that she can put new constraints on the timing of fluid flow events, from diagenesis to tectonically induced fluid flow. And this is why we went west. Much of the southwest currently lies at high elevations, a kilometer or so above sea-level. This region of elevated topography is known as the Colorado Plateau, but back in the Jurassic and Cretaceous and most likely the Paleogene, this region was submerged below sea level as part of a continental-scale seaway that extended from present day Mexico all the way up into northern Canada.

Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages. Knowing when a dinosaur or other animal lived is important because it helps us place them on the evolutionary family tree.

In areas where the basalt is from old formation dating back to the Jurassic, the are then those found in an ecotone ranging from woods to continental steppes.

Erosion resulting from the Missoula Floods has extensively exposed these lava flows, laying bare many layers of the basalt flows at Wallula Gap , the lower Palouse River , the Columbia River Gorge and throughout the Channeled Scablands. As the molten rock came to the surface, the Earth’s crust gradually sank into the space left by the rising lava. This subsidence of the crust produced a large, slightly depressed lava plain now known as the Columbia Basin or Columbia River Plateau.

The northwesterly advancing lava forced the ancient Columbia River into its present course. The lava, as it flowed over the area, first filled the stream valleys, forming dams that in turn caused impoundments or lakes. In these ancient lake beds are found fossil leaf impressions, petrified wood , fossil insects, and bones of vertebrate animals.

Both flows are similar in both composition and age, and have been attributed to a common source, the Yellowstone hotspot. As hot mantle plume materials rise and reach lower pressures, the hot materials melt and interact with the materials in the upper mantle , creating magma. Once that magma breaches the surface, it flows as lava and then solidifies into basalt.

As we learned in the previous lesson, index fossils and superposition are effective methods of determining the relative age of objects. In other words, you can use superposition to tell you that one rock layer is older than another. To accomplish this, scientists use a variety of evidence, from tree rings to the amounts of radioactive materials in a rock. In regions outside the tropics, trees grow more quickly during the warm summer months than during the cooler winter.

Each dark band represents a winter; by counting rings it is possible to find the age of the tree Figure

Fossil carbon, with a conventional age of million years, repeatedly dates to as low as 4, years. In scientists found wood buried 69 feet in a basalt.

With classic California cuisine and a lively bar at the center of everything, Basalt lets locals and visitors alike know that this is one Napa restaurant where you can get a killer cocktail. The result is an inviting space that says come as you are to wine-tasting travelers while still appealing to locals looking for drinks after work.

We sourced 80 percent of the furniture and lighting pieces from local artisans in the Napa area, with most of the rest coming from other parts of the U. The goal was to create something that felt familiar and native to Napa Valley. Higher up above the fruit crates, stacks of newspapers offer a counter balance.

It is a central feature of seafloor terrain that is more varied and more spectacular than almost anything found on dry land, and includes a collection of volcanic ridges, rifts, fault zones, and other geologic features.

At nearly 60, kilometers 37, miles long, the mid-ocean is the longest mountain range on Earth. The vast majority of volcanic activity on the planet occurs along the mid-ocean ridge, and it is the place where the crust of the Earth is born. The material that erupts at spreading centers along the mid-ocean ridge is primarily basalt, the most common rock on Earth. Because this spreading occurs on a sphere, the rate separation along the mid-ocean ridge varies around the globe.

In places where spreading is fastest more than 80 millimeters, or 3 inches, per year , the ridge has relatively gentle topography and is roughly dome-shaped in cross-section as a result of the many layers of lava that build up over time. At slow- and ultra-slow spreading centers, the ridge is much more rugged, and spreading is dominated more by tectonic processes rather than volcanism.

Scientists study the physics, chemistry, and biology of mid-ocean ridges gain insight into how Earth works in very fundamental and often surprising ways. In , WHOI scientists made a discovery that revolutionized our understanding of how and where life could exist on Earth and other planetary bodies. An ultrasound for the Earth?

Isamu Noguchi American. Water flows over this stone fountain almost invisibly. The fountain, created especially for this space, is one of the last sculptures by Isamu Noguchi, the American-born sculptor and designer. Noguchi made the work in Japan: the light stones in the fountain bed come from the Isuzu River—which flows near Ise Shrine, one of the most sacred Shinto sites—while the dark basalt stone that forms the fountain itself is also from Japan.
