The fossil reef holding Carlsbad Caverns dates from the Permian period, about 250 million years, with the caves less than a tenth as old. these caves formed and grew as the surrounding land rose well above sea level and mildly acidic rainwater percolated through natural faults and fissures, slowly dissolving and expanding the gaps. Around every turn a wonder of water works appears on scales … [Read more...]
High Plains Vista
During an unusually moist springtime, and especially after prolonged drought, relatively undisturbed parts of the American Great Plains erupt in carpets of color. Here, a dark-sky background from a stormy core and indirect sunlight through a thin spot in clouds above helped to accentuate the gaudy show of Texas Panhandle wildflowers, including vast carpets of Plains hymenoxys (Tetraneuris … [Read more...]
Morning at Öxarárfoss
Any morning spent at a big waterfall is a great use of the forenoon hours. This beautiful cascade tumbles over columnar basalt in Thingvellir National Park of western Iceland, a marvelous delight for all the senses and for the geologically curious mind. Photographing waterfalls in the daylight, with feathering, is a challenge—the key (as done here) being to maximize exposure time through some … [Read more...]

In the process, its condensation cloud underwent numerous shape changes, in and out of heavy precipitation. The lack of storm movement allowed time for plenty of simple … [Read more...]
Reunion Reflections
On a fine Dallas twilight, Reunion Tower's new LED light show sporadically displayed a geodesic-dome rendition of the American flag, while the downtown Omni Hotel did its usual psychedelic color dance, all reflected off Trinity River floodwaters. This unusual shot was the culmination of a great evening of observing and photography downstream and upriver from the Sylvan Avenue bridge. Dallas TX … [Read more...]
Horse Attitudes
While we observed the wonderfully lit scene of an onrushing gust front, these friendly horses came over for some company—and in one case, a much-craved scratching of the forehead. Their casual mood and ours each would change abruptly within minutes, and from prior experience with this storm, we knew it. A blustery plume of dirt and grit carried by the leading edge of the outflow slammed through … [Read more...]
