The ridge of sediment found by the geologist in the middle of a river, especially in the context of noticing a glacier in the distance, is likely a moraine. Moraines are accumulations of earth and stones that have been carried along and then deposited by a glacier. They can occur near glaciers and sometimes can be found in river settings where glacial activity has influenced the landscape.
