  • The Skutustadir Pseudocraters

  • What does this formation of craters have to do with water works?  The key to the answer is in the origin.  Lava flowed over wetlands or shallow lake-bottom sediments near present-day Myvatn Lake in Iceland.  The resulting steam pressure built up and blasted holes repeatedly through the same weaknesses in the overlying lava d[...]
  • Cascade from Orange Rock

  • On the highest parts of southern Utah's plateau country, characteristically orange desert rock layers have been uplifted thousands of feet into altitudes where lakes and forests cover them. Water draining Navajo Lake has tunneled a conduit through the ochre-toned sediments, rushing out of this rock wall before plunging stepw[...]
  • Frisco Hail

  • Once it was readily apparent that a supercell I had been tracking was in no substantial danger of producing a tornado, I found a drive-through overhang at a closed bank and backed in.  This would let the supercellular vault region (a notorious place for precipitation size sorting of this nature) pass overhead, with windshiel[...]
  • 22-degree Halo

  • Light from the sun or moon, bent through hexagonal ice crystals in cirrus clouds, often forms a ring removed at a 22-degree angle from the position of its source.  The coloring looks similar to a primary rainbow, but in reverse, with reds on the inside grading through yellow and green to blue and purple hues on the outside. [...]
  • Abstractions in an Icelandic Paint Pot

  • Staring into an Icelandic geothermal mud pond, also known at Yellowstone as a paint pot for obvious reasons, one can become mesmerized at the continually evolving bands of dark and light mid, deforming and stretching this way and that as the mud flows both horizontally and vertically through the system.   Zooming in to the f[...]
  • Godafoss Sunset

  • Though modest in height by Icelandic standards, Godafoss (Waterfall of the Gods) rightfully is renowned as once of Iceland's most inspiring and beautiful.  That's especially true when paired with one of those lengthy sunsets of a high-latitude summertime.  To balance the light for this shot, I employed either a 2- or 3-stop [...]
  • Scaling Hydrology

  • Purposefully composed for ambiguity of scale, this image of fluid natural artwork initially makes one unsure if the height of the photographer is closer to 3, 300, 3,000, or 30,000 feet. Stream flow courses and erodes in similar ways at vastly different scales—in this case, the best answer being 3 feet.  The best give-away i[...]
  • Crystal Daggers

  • After and despite all the destruction an ice storm can bring, the first clear, cold day that follows can offer opportunities to appreciate the peculiar spectacles in the frozen scenes.   As a gentle breeze swayed limbs in the background, making them sparkle and crackle in rhythmic pulsations of color and noise amplified by t[...]
  • Downstream Maelstrom

  • Just downstream from Dettifoss (Europe's largest waterfall) and under the plume of spray, a fluidly abstract scene roiled and roared along in the form of the  snowmelt-swollen Jokulsa a Fjollum River.  The high water, flood-producing in a few places upstream and downstream, ran a deep, muddy gray, laden with volcanic silt an[...]
  • Night Storm over the Platte River

  • Nebraska treated me well weatherwise and otherwise in 2017, despite missing out on springtime storm-intercept opportunities there.  A March trip to see the sandhill crane migration dazzled us with the experience of seeing a huge flock of them flying through a rainbow (along with snow geese, too!).  Just a couple hours before[...]
  • Summertime Supercellular Sunset

  • On our way northwest to set up for eclipse viewing two days later, we noted a massive, heavy-precipitation supercell on radar erupting out of a pre-existing, small area of thunderstorms to the distant north, in north-central Nebraska.  Too late in the day to drive closer than about 80 miles to the storm before darkness set i[...]
Lines of Inundation
  • Lines of Inundation

  • Somehow, two things conceptually as ugly as a muddy water and a chain-link fence can combine to form an abstractly interesting, uncommonly depicted, and perhaps even beautiful pattern.  I suppose, in a photographic sense, this is the equivalent of a Reuben sandwich for me:  corned beef, kraut and dressing that I wouldn't con[...]
