This week’s Imaggeo on Mondays image was taken by Prof. Konstantinos Kourtidis, in Alykes, along the southern coast of Thassos island, where he photographed the beautifully white marbles that outcrop along the coastline. The Greek Island of Thassos is located in northeastern Greece, close to the coast of Thrace in the Aegean Sea, although geographically it belongs to the Macedonia region. There is ...[Read More]

Imaggeo on Mondays: The Final Effort
We’ve all been there: long hours in the field, a task that seems never ending but which has to be finished today. This week’s Imaggeo on Mondays image is brought to you by Patrick Klenk who highlights the importance of how ‘getting the job done’ relies on good team work! Two years ago I posted this picture to imaggeo as a tribute to everyone who ever experienced the perils and pitfalls of outdoor ...[Read More]

Imaggeo on Mondays: Paramo Soil
What lies between 3000m and 4800m above sea level in the mountains of the Andes? A very special place dominated by an exceptional ecosystem: The Páramo. Picture lush grasslands with a unique population of flora and fauna, some of which is found nowhere else on Earth. Páramos stretch from Ecuador to Venezuela, across the Northern Andes and also occur at high elevation in Costa Rica. The climate her ...[Read More]

Imaggeo on Mondays: Trapped air
Can you imagine walking into the depths of an icy, white, long and cavernous channel within a thick glacier? That is exactly what Kay Helfricht did in 2012 to obtain this week’s Imaggeo on Mondays photograph. Tellbreen Glacier is a small glacier (3.5Km long) in the vicinity of the Longyearbyen valley in the Svalbard region of Norway. Despite its limited size, it is an important glacier. One of the ...[Read More]

Imaggeo on Mondays: A massive slump
One of the regions that has experienced most warming over the second half of the 20th century is the Potter Peninsula on King George Island in Antartica. It is here that Marc Oliva and his collaborators are studying what the effects of the warming conditions on the geomorphological processes prevailing in these environments. “Permafrost is present almost down to sea level in the South Shetland Isl ...[Read More]

Imaggeo on Mondays: The Valley of the Souls
Simon Gascoin captured this image of the badlands of the Palca canyon. The Palca canyon is located near the city of La Paz, Bolivia. Like much of the geology in the vicinity of La Paz, the canyon comprises mainly unconsolidated glacial formations, which are highly susceptible to wind and water erosion. The imposing spires, which can reach up to 200m in height, are fluvioglacial deposits that resul ...[Read More]

Imaggeo On Mondays: Loch Leven
Over hundreds and thousands of years, glaciers reshape the landscape beneath them. As they creep forward, the combined weight of the glacier and the perpetual forward movement means the ice continuously erodes away the rock below, permanently changing the terrain. During the last Ice Age much of Scotland and northern Britain were covered by a thick sheet of ice. Where there might have been once a ...[Read More]

Imaggeo on Mondays: Fossil dunes
Desert winds continually rework the sands on their surface, shifting grains up the stoss side of a dune to pile the sand higher… until the pile gets too steep and collapses under its own weight. This slipping of material along the front of the dune, allows it to move forward and migrate. The movement of the sand grains up and over the crest of the dunes is recorded in the internal structure of the ...[Read More]

Imaggeo on Mondays: Beneath a star-studded sky
Marco Matteucci captured this image of the night sky on the slopes of Mount Rosa, the second tallest peak in Alps. Mount Rosa straddles the border between southern Switzerland and Italy the pink mountain’s name comes from the Franco-Provençal word rouése, meaning glacier. Much off the Swiss side of the mountain is enveloped in the ice of Gorner Glacier, the second largest glacier in the Alps. On t ...[Read More]

Imaggeo on Mondays: Spectacular splatter – the marvels of a mud volcano
Mud volcanoes, unlike many others, do not extrude lava. Instead, they release glutinous bubbling brown slurry of mineral-rich water and sediment. They range in size from several kilometres across, to less than a metre – the little ones are known as mud pots, reflecting their diminutive nature. The world’s largest, though, is Lusi: a mud volcano in East Java that released an astonishing 180,000 cub ...[Read More]
