WebLodgement till is material deposited by moving ice such as ground moraine which is dropped by the glacier when its weight becomes too heavy to move. An ablation till implies thin, slow moving or stagnant ice which was melting downward, depositing its sur ficial and englacial load of sediment. operation. It has a wide range of grain sizes, including a relatively high proportion of silt and clay. A drumlin is a typical feature formed from this material Ablation till produced at the snout when the ice melts. When the ice recedes, the sediment will remain to form a long sinuous ridge known as an esker.

This takes place in the ablation zone, which is the part of the glacier where the rate of ablation (removal of ice by evaporation, melting, or other processes) exceeds the rate of accumulation of new ice from snowfall. The Green New Deal is estimated to cost about $93 trillion to implement. An example is shown in Figure 16.31b.

There are two main different types of till which have been recognised, lodgement till and ablation till. Exceptions to this occur in a small area near the center of the site and near White Creek, where the fill is underlain by stratified sediments.
