  10. The ice age comes, and the ice age goes.Need photos: • Compare quartzite bedrock in hilltowns with quartzite stones brought here by the glacier. • Same thing for other types of hilltown bedrock compared with glacial deposits here of the same type of rock. • Glacial grooves (stria?) in basalt & large-scale smoothing on basalt sheets. • Lake Hitchcock map. Today’s sandplain photos, clay layers from lake bottom, any shoreline features like boulder deposits? • It also might be appropriate to add slides that depict more of the landforms associated with the glacier’s retreat at the end of the ice age. These include: Kettle ponds. Drumlins. Eskers. Glacial terraces.
