Valley of Fire

 ...because of the waters of the flood. Genesis 7:7

"Valley of Fire is located 50 miles northeast of Las Vegas.
The name Valley of Fire comes from the red sandstone formations in the valley, called the Aztec Sandstone, which often appear to be on fire beneath the rays of the sun.
Consulting the reinterpretation chart of figure 2 we can see that a

“uniformitarian age” of 150 million years is somewhere around the Jurassic. Alongside this age the green arrow indicates it is towards
the top of “Floodwaters rising”.
In other words, the sandstone was deposited during Noah’s Flood some 4,500 years ago as the floodwaters were rising and as they were nearing their peak. On this diagram, notice the blue arrow, which indicates that after the Cretaceous the floodwaters were falling. 

Also notice that there is some overlap on the arrows to indicate that the exact location (e.g. between rising and falling) can vary depending on the area we are considering.

Long-age geologists will automatically assume that these beds were deposited by wind, rather than by water, because it would take a flood of Biblical proportions to deposit such huge dunes from water.

However, this is no problem for a Biblical interpretation because we would expect to see lots of evidence of large-scale watery catastrophe.
And that is what we see.

The enormous beds of sandstone were deposited by great volumes of

flowing floodwaters. 

The Wikipedia article on the Valley of Fire reports that other important rock formations in the area include limestones, shales, and conglomerates (composed of large rocks). 

All these were deposited as the waters of Noah’s Flood were rising."
