| Notes | About 7,600 years ago, Mount Mazama exploded in a massive volcanic eruption which led to the formation of Crater Lake. The eruption reshaped the surrounding environment in profound ways. Huge quantities of glowing pyroclastic debris were laid down, and for a time the area was uninhabitable. This publication looks at changes on the North Umpqua River that caused a series of terraces to be formed. The streamside terraces consist of original ash deposits as well as re-worked and re-deposited ash, and more recent floodplain deposits. There is evidence that humans were back in the North Umpqua area within a few hundred years of the eruption. Subsequent events such as a change in climate also affected human occupation of the area. If you are interested in the geology, geography and archeology of the region, this book chapter is a valuable find. |
