Short summary

Frozen debris lobes (FDLs) are slow-moving landslides in permafrost. Several FDLs are located adjacent to the Dalton Highway in Alaska's Brooks Range, and may pose a risk to adjacent infrastructure as their rates of movement increase. Through a comprehensive overview of eight FDLs, we found that FDL movement is asynchronous, surface features suggest that increased movement rates correlate to general instability, and the closest FDL will reach the current Dalton Highway alignment by 2023.
