Project Details

---

• Project ID:

  1552

• Nickname/Abbreviation:

  Tonsina

• Parent Project:

  Hydrology & Surficial Geology Section projects

• Status:

  Complete

• Description:

  Evaluated slope instability between Richardson Highway MP 80-82 using drillhole data collected during a field program with AKDOT&PF. Provided AKDOT&PF with a written report with recommendations for mitigating slope instability. Funded through an RSA with AKDOT&PF. Followed by study of tree-ring data from cores of spruce trees to better understand the timing and disturbance of an historically unstable slope between milepost 80 and 82 on the Richardson Highway; funded by Gas Pipeline Corridor CIP; Cooperative work with students and faculty from St. Lawrence University
