Two Coasts, Two Clocks

Use coast records to compare quick and very slow Earth events.

Read the coast records

The lighthouse crew studied two rocky places near the same coast. Read the records. Notice what changed and how long each change took.

Records from Beacon Point and Gull Rock Cove

Record 1: At Beacon Point, a strong wave struck the cliff. A small rock broke loose and fell onto the shore in 3 minutes. The crew saw the fall from the lighthouse window.

Record 2: The crew compared photographs of Beacon Point taken in 1970 and 2020. The cliff edge was 2 meters farther inland in the newer photograph.

Record 3: At Gull Rock Cove, the crew compared a pebble collection from 1820 with one from 2020. The newer pebbles had smoother edges. The two collections were made 200 years apart.

Record 4: Markers on the ground showed that Gull Rock Cove rose about 4 centimeters between 1800 and 2000. People would not notice this change during one visit, but the measurements showed a difference over 200 years.
