Slickrock Trail

Slickrock Trail is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Slickrock Trail rather than just read about it. In short: The Slickrock Trail, is a popular mountain biking destination in Grand County, Utah, United States, a few miles northeast of the city of Moab. This 10.5-mile (16.9 km) trail takes riders over a landscape of petrified sand dunes and the eroded remnants of ancient sea beds.

Key takeaways

Slickrock Trail belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Slickrock Trail to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Slickrock Trail from memory before moving on to harder problems.

Reference excerpt

The Slickrock Trail, is a popular mountain biking destination in Grand County, Utah, United States, a few miles northeast of the city of Moab. This 10.5-mile (16.9 km) trail takes riders over a landscape of petrified sand dunes and the eroded remnants of ancient sea beds. Mountain bikers rate the Slickrock Trail as one of the more difficult rides in the Moab area, both technically and cardiovascularly.

Description

Part of the Sand Flats Recreation Area (which is managed through a partnership between Grand County and the Bureau of Land Management), the Slickrock Trail was originally laid out in 1969 by Richard R. Wilson for use by Honda Trail 90s (before the mountain bike was invented), and the area is still open to such recreation today. 4X4 and off-road enthusiasts will find a challenge on the nearby Hell's Revenge 4X4 Trail, which intersects the Slickrock Trail in several places. The so-called "slickrock" sandstone, which forms the majority of the trail's surface has a surface much like sandpaper, making it really grippable by the rubber tires of a mountain bike or off-road motorcycle. The texture is notorious for inflicting severe abrasion injuries. The name "slickrock" was used by early settlers of the area to describe the sandstone because of the low traction between horses' metal shoes and the rock's sloping surfaces. The same is true today for cyclists who use shoes with metal cleats while riding the Slickrock Trail. Slickrock also becomes slick when wet.

In geological terms, the Slickrock Trail is not part of the Entrada Sandstone formation, which includes the Slick Rock Member. Rather, most of the outcrop that forms the trail is Navajo Sandstone, and the term "slickrock" has come to mean any expanse of sandstone with a surface level enough for walking or riding. A small fee is required to enter the Sand Flats Recreation Area. Pit-toilets are available at the trailhead, but there is no drinking water available within the area. Permitted trail activities include mountain biking, hiking, and motorcycling. All four-wheeled vehicles are prohibited on all of the Slickrock Trail, except those sections which intersect with the Hell's Revenge 4X4 Trail (which occurs about six times).

Course The Slickrock Trail consists of three main sections: An out-and-back lead-in (akin to the stick of a lollipop or stem of a cherry), the main 6.8-mile (10.9 km) loop (akin to the fruit of a cherry or the candy part of a lollipop), and an optional 2.3-mile (3.7 km) practice trail (also called the practice loop, although it is not literally a loop) that begins and ends at separate points on the lead-in. The practice loop is about as hard as the rest of the trail, but it is shorter and close to the trailhead, serving for new riders as a sample of the rest of the trail or as an alternative return and or departure route. The lead-in, main loop, and practice trail are marked out by white, dashed lines on the rock to prevent riders from straying from the trail, becoming lost, or disturbing the fragile cryptobiotic soil near which the trail passes. Trail maintainers also use yellow markings near blind drop-offs, narrow ledges, and other features to indicate to riders where to be particularly careful.

Worked examples

Example 1 — a first encounter with Slickrock Trail

Start with the simplest possible case. Write down what Slickrock Trail claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Slickrock Trail before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Slickrock Trail ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Slickrock Trail

In research: Slickrock Trail appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Slickrock Trail in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Slickrock Trail is common in secondary-school and first-year university syllabi. It links to neighbouring topics Geologic formations with imbedded sand dunes, Moab, Utah, Mountain biking venues in the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Slickrock Trail outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
