Mitigation Options to Reduce Icing and Thaw Instability Problems on the Denali Park (Alaska) Access Road

Ted S. Vinson (Department of Civil, Construction and Environmental Engineering, Oregon State University, Corvallis Oregon 97331, USA)  
Only one access road leads into Denali Park. The serviceability and safety of this gravel road is obviously of paramount importance to the National Park Service (NPS). Since the late 1950s and mid-1960s major icings and a landslide, respectively, have occurred along the Denali Park access road. During the summer of 1990 the landslide activity intensified. The central section of the Park through which the access road traverses is designated as a wilderness area. Consequently, off road field exploration required to quantify the hazards and remediation activities that may be proposed to mitigate icings and stabilize the landslide, are severely restricted and closely scrutinized by the NPS. The results of an evaluation of (1) the current state-of-the-practice to control icings, and (2) thaw stabilization techniques that could be applied to the northwest corner of the landslide are presented herein. The recommendations which followed, respecting the wilderness area designation for the Park, are also presented.
