Abstract: Construction of fixed facilities on rock glaciers is rarely undertaken. These masses of ice/rock aggregate move downhill under the influence of gravity and are subject to ablation of the ice. The Big Sky Tramway project required construction of a major facility on a rock glacier near Lone Mountain, Montana. Through careful engineering and research, appropriate mitigation techniques were developed that allowed for construction of the facility. Discussion is provided of the technical issues involved and the engineering solutions that were used to address those issues. Evidence of the success of this work is the continued operation of the tramway system five years after installation. The base terminal of the tramway may require installation of a thermosyphon system that was planned for during the initial construction if ice ablation is later found to affect the facility.
