Sample 17 is a striated and faceted stone embedded in a sandy diamictite matrix. The erosional surfaces of the pebble suggest that it was in direct contact with mobile basal ice. The flattened (faceted) surfaces of the pebble were formed as the pebble scraped along the bedrock beneath the moving basal ice. The striations that appear as parallel grooves etched into the faceted surface of the pebble record the direction of ice movement.
This sample is from the Storeelv Formation in eastern Greenland.
The sample is 10 cm across at its widest point.
