On November 16, 2022, we visited a strange landscape of tortured red rock, slot canyons, and blue sky:  the Valley of Fire State Park in Nevada. The Aztec Sandstone in the area is so red, that a traveler in the early part of the 20th century who happened to travel through it at sunset said that it looked like the whole valley was on fire.  The name stuck.  
There are many nice hikes in the park.  One of these goes to Mouse's Tank.  This is an interesting "waterhole" in a deep recess in the rock.  
One can only imagine how the early travelers through this area must have appreciated the water in Mouse's Tank on a hot summer day, but why is it named after a mouse, a very small and not very impressive animal?  Well, it is not named after the animal, but rather after a notorious outlaw. 
According to the Utah Adventure Family website, Mouse was an outlaw, and he hid out in the Valley of Fire near Mouse's Tank.  Nobody else seemed to know about it, and Mouse could stay there until things cooled down. Even though he was in the desert, he usually had lots of water to survive.  Apparently the tank, does not always have water, but on our visit the water was cool and deep, as can be seen in the picture below.  

It is hard to imagine a more serene and awe-inspiring place than Zion Canyon in southern Utah.  Today it is the centerpiece of Zion National Park, the second most-visited national park in the USA. The Mormons, who arrived in Utah in 1847, explored the canyon in the 1850s and were obviously just as impressed as we were in 2022.  They named it Zion. “Zion” is a hill in Jerusalem but is also used in a general way to refer to a holy place or to the “kingdom of heaven.” 
Frederick Vining Fisher, a Methodist minister from Ogden, Utah, visited the valley in 1916, and was equally impressed.  He seems to have felt that only biblical names could do justice to the beauty of some of the geological features of the canyon.  He named three prominent sandstone peaks along the Virgin River after Abraham, Isaac, and Jacob of the Old Testament.  Today they are known as the Three Patriarchs.
The Mormons added a fourth to the three.  A nearby peak was named after the Angel Moroni, who was reported by Joseph Smith, founder of the Mormon religion, to be the guardian of the golden plates which are believed by Mormons to be the source material for the Book of Mormon.

In the photograph of the Three Patriarchs below, the three white-capped sandstone peaks from left to right are named Abraham, Isaac, and Jacob.  The red-topped peak between Isaac and Jacob (more or less in front of Jacob) is Mount Moroni.
