Imaggeo On Monday: Contorted Streams on the Gates Glacier

Allen Pope December 20, 2021

Supraglacial streams in ogives, Gates Glacier

Annual ridges and troughs (called wave ogives) are formed as the ice of the Gates Glacier (in Alaska’s Wrangell Mountains) flows through a steep icefall. Down-glacier, as the ice melts, the rushing meltwater is funnelled into streams, carving ice canyons as it flows, but ultimately directed by these topographic constraints.

High altitude karstic environments often preserve permanent ice deposits within caves, representing a lesser-known portion of the cryosphere. Despite being not so widespread and easily reachable as mountain glaciers and ice caps, ice-caves preserve a great deal of information about past environmental changes and paleoclimatic evolution. Since one of their main characteristics is to have ground-ice ...[Read More]

Aerial view of the Chuquicamata copper mine in Northern Chile. This is the largest open pit copper mine in the world by volume (at the time of sharing). At this location the copper and molybdenum is extracted from a porphyry deposit that was formed beneath a volcano in the Andean subduction zone. Description by Martyn Unsworth, after the description on imaggeo.egu.eu. Although much o ...[Read More]

The Mutnovsky Geothermal Power Plant is the largest geothermal power plant in Russia (the time of writing). It is located near to volcanic mountain Mutnovsky at altitude of 800 m and has a capacity of 50 MW. The Mutnovsky Geothermal Power Plant has resolved the problem of raising the stability of the power supply for the Kamchatka region, at the expense of using the richest stocks of thermal heat ...[Read More]
