422. A GeoMystery Field Trip to the Anton Escarpment
|
| Primary Leader: David C. Noe |
| Field Trip Description: Everybody loves a mystery. One of Colorado's great mysteries is the origin of the "Anton escarpment" that crosses eastern Colorado's high plains for nearly 100 miles. Was it formed by movement along a fault? If so, what is the timing? Or is this straight-line feature a product of massive, late Pleistocene erosion? The highlight of this field trip will be the examination of new research trenches dug into the slope of the 80-ft-high escarpment. We will look at trench stratigraphy and archeology, and (if present) indicators of seismogenic movement. Because these trenches will be dug later in 2007, even the field trip leaders don't know exactly what we'll see! |
| Field Trip will span: 1 day |
