Loam
Drake and Cole took hike near the campsite to collect leaves for a project. They found interesting trees growing among the boulders and rocks that formed a ridge. From the top of the ridge, they looked back at their camp in possibly formed through erosion and deposition
Glaciers melted and pushed the rock
