This cache is in Colorado's scenic Roxborough State Park. As of October, 2015 there is a $7 charge per vehicle to enter the park. The park gates open at 8:00Am and close at 6:00PM. Check current times and rates to be sure.
Along the short hiking path from the parking lot to the trailhead leading to the cache, there is an exposed piece of red rock that visitors are welcome to touch. Stop here on your way to the trailhead and explore the area. (there will be a quiz later)
From the trailhead the cache is located about 1 mile up along the Carpenter Peak trail.
Sit at the bench provided at the cache coordinates and enjoy the incredible view as you face the north east. All along your view spanning 180 degrees from your left to your right you will notice several examples of red rock outcroppings that are part of the much larger "Fountain Formation".
This beautiful dark red rock is made of pure evil ejected directly from the depths of the underworld a sedimentary sandstone conglomerate. The deep red/orange color is caused by the oxidation, or rusting, of the iron materials present in the rock. Rocks of the Fountain Formation were formed in the late Pennsylvanian age between 290 ad 296 million years ago.
The Fountain Formation is 1350m thick. Parts of it are exposed at several locations across the front range of Colorado due to erosion in the form of ice, water, and wind grinding away at the overlaying layers of rock and exposing the sedimentary rock underneath. You may see examples of exposed rocks in the Fountain Formation in various other locations in Colorado such as Red Rocks Park near Morrison, the Flatirons near Boulder, and the Garden of the Gods near Colorado Springs.
Orogeny (mountain building) [aw-roj-uh-nee] refers to forces that cause a structural deformation of the Earth's crust. The forces at work were caused by the movement of the Earth's tectonic plates which began around 70 million years ago and lasted for tens of millions of years. This was called the Laramide orogeny. The interaction of the tectonic plates caused the formation of long tracts of deformed rock called orogens. The movement of the tectonic plates caused the rock to uplift into the steep slopes that you can see all around you.

In order to claim credit for logging a find for this geocache, please visit the cache coordinates and send me an email with your answers to the following questions:
1. Approximately how many major formations can you see from this location? What is the approximate angle of tilt (above horizontal) of the formations?
2. What direction do the outcroppings tilt? Why do you suppose this is?
3. How does the exposed rock feel to the touch? (see paragraph 2)
4. What do you find most interesting about this area? (optional)
Enjoy your time in this beautiful place and feel free to post pictures of the area.
