Devil’s

   Slide
I have always been fascinated by this slide since I
was a little kid. Why take your kids to an ordinary playground
slide at the park, when you can go to the slide named after the
Devil himself? Unfortunately for sliders, Devils Slide is not a
real slide, but an unusual geologic feature found in northern Utah.
Devils Slide is a classic example of how different rock layers,
depending on their composition, are affected by weathering and
erosion.

The sides of the slide are hard, weather-resistant
limestone layers about 40 feet high, 25 feet apart, and several
hundred feet in length. In between these two hard layers is a
softer limestone that is slightly different in composition from the
outer limestone layers. This middle layer is softer, which makes it
more susceptible to weathering and erosion, thus forming the chute
of the slide. Looking like a large playground slide fit only for
the Devil, this site is a tilted remnant of sediments deposited in
a sea that occupied Utah’s distant geologic past. Approximately 170
to 180 million years ago, a shallow sea originating from the north
spread south and east over areas of what are now Montana, Wyoming,
and Utah. This sea extended as far east as the present-day Colorado
River and south into northern Arizona. Over millions of years,
massive amounts of sediment accumulated and eventually formed
layers of limestone and sandstone. In northern Utah, these rocks
are known as the Twin Creek Formation and are approximately 2700
feet thick. About 75 million years ago, folding and faulting during
a mountain- building episode tilted the Twin Creek rock layers to a
near-vertical position. Subsequent erosion has exposed the
near-vertical rock layers and created Devils Slide. 

How to get to Devils Slide: 1. From the I-15/U.S.

Highway 89 interchange in Farmington; head north on U.S. Highway 89
for 10.7 miles to a sign indicating the route to Morgan and
Evanston. Turn right (east) on I-84 and travel approximately 23
miles to the scenic viewpoint turnoff located after milepost 110.
or 2. From the southern I-15/I-80 interchange in Salt Lake City;
head 11.3 miles east on I-80 to exit 134 (Mountain Dell Recreation
exit). Travel north on Utah State Highway 65 for 27.7 miles to the
town of Henefer. Turn left (west) and proceed 1 mile to I-84. Turn
left (west) onto I-84 and travel 2 miles to the scenic viewpoint
turnoff located just after milepost 111.

To get credit and

claim a “Find” for this EarthCache you must post a picture of
yourself and your GPS in front of Devil’s Slide and send us: An
Email telling us what type of “softer” Limestone is on both sides
and within the center of the slide. (This information can also be
found online if not known). And tell us if you were to walk
directly up the Slide, what bearing would you be heading? And
provide us with an educated quess as to what the elevation gain is
from the bottom of the Slide to the top.
