Reconstruction boundaries Snow of late Quaternary in the range of site Rig

Territories glacier Rig site in the south province Chahar Mahal and Bakhtiari was studied with the aim tracing evidence of glacier activity, determining boundaries snow the, reconstruction of conditions past humidity and temperature, determining balance line of water and ice of late Quaternary and reviews link between scattering cirques with aspects inequalities. with aspects. From method Interpolated in reconstructing of climatic and hydrological data and also study method Porter Cirque floor and Wright method was used to determine the past boundary of the snow. The results from Porter's method, altitude 2812 and also of the method Wright, altitude 2836 meters shows as past boundary snow. Also water and ice balance line obtained has been in the altitude 2109 meters. The results represents the shaping are about 89/32 % of the Cirque at the slopes of to pole and the 66/25 % other in the slopes to the the equator.
