Abstract

An abandoned auto tunnel in south central Alaska in an elevation of 118 m above sea level seemed to be a perfect laboratory for studying the evolution of ice speleothems in a yearly cycle. More than 1,500 ice forms like stalagmites, stalactites, columns in various shape and arrangements, developed in just 2 month to a high up to 6 meters and lasted for another 5 to 6 month. In October just the remains of the melted ice in rings and rectangular patterns of a white powder could be found. Unfortunately the mostly sealed tunnel was opened in January 2014 by melt water stream which was redirected by a huge avalanche.

The perfect “ice cave conditions” were destroyed abruptly (HOLLANDER & THERIAULT, 2014; NASA; 2014a).

Climate Study In An Abandoned Auto Tunnel In Alaska, Usa
