    Frozen Water on Mercury, NASA Confirms

    Mercury, the planet closest to the Sun, may hold at least 100 billion tons of ice in permanently shaded craters near its north pole, NASA scientists announced Thursday. The findings come as NASA’s MESSENGER spacecraft nears its second year of orbit around Mercury. MESSENGER’s lead investigator, Sean Solomon, is director of Columbia University’s Lamont-Doherty Earth…

    Tree Rings to Investigate Chimborazo’s Past Climate

    The landscape around Chimborazo resembles the high desert in parts of the western United States. The terrain approaching Chimborazo is arid and rocky in appearance, with mostly small grassy and shrub-like vegetation growing on it. Finding trees large enough to sample above 4000 meters was, needless to say, a bit of a challenge, but they…

    Putting Up Weather Station Chimborazo

    Changes in glacier mass will have significant social and economic consequences for cities around Chimborazo and I’m hoping the specially built weather station will shed more light on the climate factors contributing to glacier loss.

  • After Sandy, Testing the Waters

    After Sandy, Testing the Waters

    During Hurricane Sandy the seas rose a record 14-feet in lower Manhattan. Water flooded city streets, subways, tunnels and even sewage treatment plants. It is unclear how much sewage may have been released as plants lost power or were forced to divert untreated wastewater into the Hudson River. Four days after Sandy, the environmental group…

    Cotopaxi Skies

    Because of Cotopaxi’s almost perfectly conic shape, the climb appears be a straight line to the top. It isn’t. In fact, the climb winds past spires of ice and vast blue crevasses the size of small canyons. Cotopaxi is a beautiful mountain.

  • Sleepless in Cayambe

    Sleepless in Cayambe

    The night is spent enduring the constant pinging of text messages, music and lights being turned on in the sleeping area every time someone comes or leaves. One thing to avoid before an Alpine Start (12.30am) is a night without sleep.

    Sandy’s Surge Affected More Than 1.4 Million in 11 States

    Based on a model used by the U.S. Federal Emergency Management Agency (FEMA), the map shows coastal areas likely to have been inundated by the storm surge resulting from Hurricane Sandy, in relationship to residential population.

  • Next, Imbabura

    Next, Imbabura

    Today was a much longer climb up Imbabura, passing through more páramo until reaching our first Polylepis trees. Conveniently, they were marked by a little wooden sign. These are the trees that I hope to sample next week on Chimborazo.

    After trudging through the paramo, our route becomes a high-altitude scramble on an exposed rocky granite spine with sheer drop-offs on either side. The surge of adrenaline keeps our minds off the thin air.
