Early formation of gnammas (weathering pits) in a recently glaciated area of Torres del Paine, southern Patagonia (Chile)

Authors(s) and Affiliation(s)



The gnammas were located on the granite blocks of a lateral moraine deposited during a Late Holocene neoglacial advance. They were measured for maximum and minimum depth, length, and width in addition to other observations, in the Francés Valley of Torres del Paine. Based on these measurements, the surface area and the volume of the gnammas were calculated. Finally, the Francés Valley population is compared with an older gnamma population to discuss the significance of the results for gnamma morphometric analysis
