The Fiery Furnace gets its name from how it appears in the warm light of sunset.
Here's a sunset reflected in a park sign about the Fiery Furnace.
Because of some difficult passages, and because of the likelihood of getting lost, you need a special permit to enter the Fiery Furnace, and most people go in the company of a ranger guide. Photos showing things like the scene above discouraged Teddie from going on the hike, and so Carl went alone.
We start off on our hike into the Fiery Furnace in the company of a park ranger.
Immediately the trail got a bit difficult.
Down in the Furnace among the numerous, high, very vertical rock formations.
Fiery Furnace hike.
Lots to see, including looking up. The photography was difficult because of the strong contrast between lit and shadowed areas.
Fiery Furnace hike. This is our first arch on the hike, called "Step Through Arch". It was quite dark in this spot, hence the slow shutter speed and the blurred look.
Near Step Through Arch, this is a multi-image pano looking from straight up overhead down to the ground ... Hard to get the feeling from photographs!
Looking up from one of the many canyon floors.
An official "Arch" must have a 3-foot wide opening. This little arch is thought to be the smallest official arch in Arches National Park. And, yes, that is me squeezing through it, and pushing my backpack through it. Thses shots taken by a fellow hiker.
Step Through Arch. From this one you can get a good sense of the strong contrast in light making it difficult to do photography.

Fiery Furnace hike. This Pothole was still full of water. We stopped by it to rest and to get a lecture from the ranger about the kind of life that lives in such potholes, even when they go dry. Roll your cursor up and off this caption to see the bottom of the photo.
An example of the microscopic life that lives in the Photholes, even in the soil after they go dry in summer. It is incredibly durable, as evidenced by the next slide ....
Water Bears, the common name for the microscopic animal in the previous slide, are incredibly durable. They can survive almost anything ... except people walking on the dried pothole soil!
Fiery Furnace hike. Above us at the pothole hung this spectacular arch, the Twin Arch.

An alternate name for Twin Arch is Skull Arch.
The ranger supervises maneuvers over one of the many difficult places in the hike.
This transition required a controlled slide down the rock; there was no stopping oneself.
