Partway up a 350-foot tree, botanist Marie Antoine (at right) passes a slender core sample of its wood—750 years of redwood biography—to canopy ecologist Giacomo Renzullo. Research now shows that the older such trees get, the more wood they put on. See more pictures from the October 2009 feature story, "The Super Trees."

This Month in Photo of the Day: Adventure and Exploration Photos
A volcanologist strides through a murky expanse of steam on Mutnovsky Volcano during an expedition to Kamchatka, Russia. The steam billows from a fumarole, or a vent created by heated groundwater and rising volcanic gas, and it serves as a visible reminder that the peninsula is one of the most volcanically active regions in the world, with some 29 active volcanoes.

The long retention of low temperature favored the icing of small Sopot waterfall on Medvednica mountain. The red sky comes from the city lights of nearby Zagreb. Sopot waterfall is the only one in the area, therefore alpinists from Zagreb use every chance for climbing it and staying in shape. (This photo and caption were submitted to Your Shot.)

Following the guideline her life depends on, a diver threads the needle through a stalagmite forest in Dan's Cave on Abaco Island. A single, misplaced fin kick can shatter mineral formations tens of thousands of years old. See more pictures from the August 2010 feature story "Deep Dark Secrets."

Climber John "Razor Sharp" Benson weaves through skin-ripping pinnacles. In Malagasy, the formations are called tsingy, meaning "where one cannot walk barefoot." The terrain resists intrusions from hunters, hungry cattle, and wildfires. See more pictures from the November 2009 feature story "Living on a Razor's Edge."

The crash of rapids surrounds expedition leader David Gill, left, and Herb Laeger near the entrance of Ora Cave. Hot acidic waters welling up from deep underground, combined with drainage from heavy rains, have carved a maze of tunnels and chambers through New Britain’s young limestone. See pictures from the September 2006 feature story "Raging Danger."
