Imaggeo on Mondays: Ephemeral winter wonderland
Today’s text is brought to you by the author of this impressive picture, Patrick Klenk (Heidelberg University, Germany). This photograph is part of a series of images which I took in Death Valley National Park on a brisk December morning in 2011. In this case, we were close to Aguereberry Point, a mountain viewpoint located at 1961m above sea level, overlooking the central part of this “vast ...[Read More]

Friday Photo (58): Active Geology – Striations on a Fault Surface, Greece
An active fault surface in Greece – one of the most seismically active places on Earth. The striations on the surface can be used to measure the direction of movement on the fault. The exposed surface can be dated at various heights (using dating systems such as Beryllium-10) to infer the rate of slip. (c) Geology for Global Development

Polygons, columns and joints
Over on her Georney‘s blog, Evelyn Mervine has recently posted a nice piece with some spectacular images of columnar jointing. This seemed like a good opportunity to dust off some field photos, with some more examples of polygonal joint sets in lavas from a variety of settings, to illustrate the diversity of forms that cooling-contraction joints may take in volcanic rocks. The first example ...[Read More]

Imaggeo on Mondays: Gullfoss, Iceland
For anyone who spent the 1980s jamming to British band Echo & the Bunnymen, this is a familiar sight. The cover of their third studio album, Porcupine (1983), features the band nonchalantly standing in front of the gushing white foam of Iceland’s Gullfoss waterfall. Mentioned in local written stories and beamed across the world in music videos, the Gullfoss falls occupy a mythical place in hum ...[Read More]

Friday Photo (57): Active Geology – Sinking Buildings from Ancient Greece
These foundations were once part of a building in ancient Greece. Over thousands of years, active faults have lowered the land and the foundations have sunk below sea level. Geology can have a big impact on relatively short timescales. (c) Geology for Global Development
