White Dome Geyser & Aurora
The Aurora extended to southern Montana and into Wyoming just before and after midnight on Sept 30/Oct 01. The rising full moon spotlighted the erupting White Dome Geyser in Yellowstone National Park. — Robert Howell
Scientists from the University of Southampton have identified a repeating trigger for the largest explosive volcanic eruptions on Earth.
By analysing crystal cumulate nodules (igneous rocks formed by the accumulation of crystals in magma) discovered in pyroclastic deposits of major eruptions, the scientists found that pre-eruptive mixing within the magma chamber — where older cooler magma mixed with younger hotter magma — appears to be the repeating trigger in large-scale eruptions.

a greater adventure awaits
A massive explosion aboard the Deepwater Horizon oil rig in the Gulf of Mexico in April 2010 led to largest crude oil spill in the history of the petroleum industry. Photographer Daniel Beltrá, in his continuing devotion to celebrating the world’s ecosystems via his camera, captured these remarkable images to document a horrific disaster that continues to impact the economies and the natural environs of Gulf region inhabitants. Entitled Spill, the collection of aerial images is, visually speaking, equal parts beautiful and tragic.

Sunset Crater Volcano National Monument
Sunset Crater Volcano! Roughly 900 years ago, the eruption of this volcano reshaped the surrounding landscape, forever changing the lives of people, plants and animals. Hike the trail through the lava flow and cinders and you’ll likely discover colorful, ruggedly dramatic geological features coexisting with twisted Ponderosa Pines and an amazing array of wildlife.
Rio Grande River
A truly grand river.
The Giant’s Causeway (known in Irish as Clochán an Aifir or Clochán na bhFómharach) is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption. It is located in County Antrim on the northeast coast of Northern Ireland
But coral reefs are not lost and will not be if we take proper action — and science is showing us the way. Abandoning hope for coral reefs not only is reckless and dangerous for those who depend on these amazing ecosystems — it is one of the most unscientific things a conservationist today could do. — Stephanie Wear, Nature Conservancy director of coral reef strategy
