There are two types of ways dead ice can melt: backwasting and downwasting. Backwasting is when the dead ice melts parallel to an ice-wall or ice-cored slope. Backwasting is more likely to occur when an area is fully ice-cored. Downwasting is when dead ice melts at its top and bottom surfaces. Both

Dead ice is created when a glacier or ice sheet experiences an increase in melting and accumulates debris from various sediment sources. The debris seeps into the ice, effectively covering the surface area. This leads to the affected area becoming mixed with different types of debris, ultimately

dead ice melting rates depend on the climate condition of the area it is in; however downwasting has several other factors that contribute to its process. Another factor that affects both melting rates is the type of debris that covers the dead ice.

slowing the glacier's melting rate. This process continues over and over, creating layers of ice and debris, until it forms dead ice. Dead ice most commonly occurs on
