0 years ago. These lava dams blocked the river for tens of thousands of years, and the lakes behind them had to fill with sediment before the river was able to transport sand and gravel over the dam crest and carve through the dams. Once incision through the dams began, it was several times greater than the average long-term rate of canyon formation. The resulting landscape of flat, broad lava layers capping steep cliffs of softer sediment is conducive to landslides, some of which in turn dammed the river and produced large floods when the dams failed. Thus, well beyond the lifetime of the lava dams, the lava flows indirectly continue to affect the river canyon landscape.

The history of life on Earth is recorded in the stratigraphic record. Stated another way, the rocks that make up the Earth itself are a book that contains the story of our planet's tumultuous history. The interactions between climate, biology, the oceans, and the atmosphere are all preserved in the rock record, and it is the job of geoscientists to decipher these events. As expected, however, deciphering this history gets increasingly complex the further back in time one chooses to look. A particularly large stumbling block to the study of Earth history in deep time (many hundreds of millions of years ago) has traditionally been our inability to determine precise and reliable dates and durations of ancient global change events. Bradley D. Cramer of the Kansas Geological Survey and colleagues combine a series of recent advances in analytical chemistry together with recent a
