Coastline Breach
A breach in the coastline of Rodanthe, North Carolina, caused by Hurricane Irene in 2011. Repeated storm impacts, combined with sea level rise, make the development and improvement of models that help forecast coastal change very important to planners working to build more resilient communities

Baydzherakhs
These are baydzherakhs that form when Pleistocene-aged ice wedges thaw and leave behind a mound of unfrozen soil that is easily susceptible to decomposition. This sediment has not thawed for at least 40,000 years.
