The top part of this formation has moved sideways over the years. It looks like it is balanced precariously and will fall over at any moment, but it will probably be hundreds or thousands of years before that happens.

This is the "famous" Balancing Rock formation. The lower portion is a softer rock and has eroded faster than the top "balancing" portion, which is supported by a small piece of a harder layer. The view from the parking area does not convey the immense size of the balancing rock...

...as you walk down the trail, it gets bigger and bigger, until you realize it is about the size of a two or three bedroom house! You would think it should have squashed the lower, softer rock long ago.

One of the unique features of the desert landscape is the cryptobiotic crust. This crust of cyanobacteria, mosses, lichen, fungi, and algae binds the loose soil, absorbs water, and provides a bedding platform for other plants.

|
Some of the best examples of cryptobiotic crust are at Natural Bridges National Monument.

Here is a closer view of the cryptobiotic crust and a few plants that have taken root. It is extremely fragile, and a single footprint may take years to "grow back".
