Insights into the frictional rheology and hydrology of a rock slope instability from in-situ monitoring near Columbia Glacier, Prince William Sound, Alaska

Since 2023 we have instrumented a large, creeping bedrock landslide near the calving face of Columbia glacier in Prince William Sound, Alaska.  With an eye towards better mitigating the hazards associated with large rock slope instabilities in coastal Alaska, I will highlight some of what we have learned about the mechanical and hydrological behavior of this landslide from our instrumentation.
