Dating Lava Flows on Mauna Loa Volcano, Hawaii
For hundreds of thousands of years, lava flows have created intricate patterns on the slopes of Hawaii's Mauna Loa volcano. Until the mid-1970s, it was impossible to know when each of the flows occurred. However, as this video segment describes, a researcher has discovered a way to date the flows by determining the age of carbonized plant remains that they covered. The segment is four minutes thirty-three seconds in length. A background essay and discussion questions are included.
