摘要: Modern deglaciation in Sierra Nevada. Morphogenetic effects, new data and outlook regarding future studies. During the Little Ice Age a small glacier occupied Veleta cirque (Guarnon glacier, Nevada, Spain). The successive melting disappearance of during first half 20th century were followed by construction talus cones located at foot wall. Debris buried residual ice body. At present are fed clasts from wall show peri- glacial processes as gelifluction ice-creep. These mainly controlled persistence snow cover. Among periglacial landforms rock is most interesting feature. Therefore, thermal morpho- metric monitoring undertaken. obtained results point to degradation alpine permafrost.
