Here is the question :
WHAT IS THE “PARADOX” IN COLORADO’S PARADOX VALLEY?
Here is the option for the question :
- The valley isn’t actually a valley
- The valley floor is completely barren
- Its river runs perpendicular to the valley
- There is no paradox
And, the answer for the the question is :
[STC00977] The Dolores River holds the key to solving the riddle of the enigmatic paradox that has been plaguing Paradox Valley. Since the sandstone canyon walls that surround the valley are almost a thousand feet high and run from north to south, geologists would anticipate the river that runs through the valley to flow in the same way as the canyon walls. On the other hand, in a particular section of the valley that is about five miles long, the river runs in a direction that is perpendicular to the canyon walls and travels from west to east. The unusual occurrence of this paradox is due to the fact that a salt dome was pushed under the river. The salt was dissolved by the groundwater that made its way into the dome, which led to the dome’s eventual collapse into a basin. Therefore, the river began to flow across the valley rather than down it, which resulted in the peculiar topographical feature that served as the motivation for naming the valley.
