Slide 47 of 66
Notes:
Here is a view of the 60 m tall badland slopes and part of the pediment surface that leads from the base of the badlands to the modern level of the Fremont River. Examples of the sandstone gravel-capped surfaces grading to the Wisconsinan terraces along the Fremont River are shown by the red arrows. Based upon the geometric relationships and the fact that the badlands never extend above the level of these gravel remnants, the interpretation is that a pediment level over the entire area formed at the time that Wisconsinan gravel terraces formed along the Fremont River, which corresponded to glaciation in the mountains west of this site. This pediment surface led from the sandstone scarps to the Fremont River, and were capped by sandstone shed from the actively-backwasting scarp. Dissection of the Wisconsinan pediment has resulted in the badlands seen here.
