Mount Bailey (Oregon)

Mount Bailey (Oregon) 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 Mount Bailey (Oregon) rather than just read about it. In short: Mount Bailey is a relatively young tephra cone and shield volcano in the Cascade Range, located on the opposite side of Diamond Lake from Mount Thielsen in southern Oregon, United States. Bailey consists of a 2,000-foot (610 m)-high main cone on top of an old basaltic andesite shield volcano.

Key takeaways

Mount Bailey (Oregon) 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 Mount Bailey (Oregon) to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Mount Bailey is a relatively young tephra cone and shield volcano in the Cascade Range, located on the opposite side of Diamond Lake from Mount Thielsen in southern Oregon, United States. Bailey consists of a 2,000-foot (610 m)-high main cone on top of an old basaltic andesite shield volcano. With a volume of 8 to 9 km3 (1.9 to 2.2 cu mi), Mount Bailey is slightly smaller than neighboring Diamond Peak. Mount Bailey is a popular destination for recreational activities. Well known in the Pacific Northwest region as a haven for skiing in the winter months, the mountain's transportation, instead of a conventional chairlift, is provided by snowcats—treaded, tractor-like vehicles that can ascend Bailey's steep, snow-covered slopes and carry skiers to the higher reaches of the mountain. In the summer months, a 5-mile (8 km) hiking trail gives foot access to Bailey's summit. Mount Bailey is one of Oregon's Matterhorns. Native Americans are credited with the first ascents of Bailey. Spiritual leaders held feasts and prayer vigils on the summit.

Etymology The origin of the mountain's name is a matter of dispute. Older maps show its name as either "Old Baldy" or "Old Bailey", "Bailey" possibly being a drafting error. The summit's bald, burnt-over appearance might indicate the origin of the designation "Baldy". No record of a person named Bailey who was connected with the peak has been found. In 1992, the Oregon Geographic Names Board voted to name the mountain in honor of naturalists Vernon and Florence Bailey. According to William G. Steel, the Klamath name for the mountain was Youxlokes, which means "Medicine Mountain". According to Klamath tradition, their medicine men and priests would feast on the mountain's summit and commune with the upper world.

Geography and geology Mount Bailey is part of the High Cascades in the western United States. The High Cascades have long been glaciated, by both Pacific-bred storms and natural, elevation-caused, glaciation. In fact, glaciation probably formed on them as early as the late Miocene. Over time, as the range built up, newer activity diminished older Tertiary age rock. Creating lava plateaus, Pliocene activity, mostly basaltic and andesitic, was probably responsible for the original cones at Bailey, Thielsen, and Union Peak. Mount Bailey heads the Mount Bailey chain, which consists of the mountain and smaller cinder cones trending north. Similarly to its neighbor Mount Thielsen, it is a shield volcano with precipitous summit slopes. Built around the same time as Rodley Butte, according to morphological study, the current volcano is no more than 100,000 years old, and formed relatively close to Diamond Peak's current cone. Despite its similarity to Rodley Butte, both in age and original composition, Bailey switched from erupting basaltic andesite to andesite. Bailey is comprised by a central tephra cone, upon which basaltic andesite eruptions streamed over, building up to create the current volcano. Eventually switching to andesite, it may have been built over several eruptions or even eruptive periods, judging from the silicic nature of its rock. It is currently inactive, having been since approximately the time Mount Mazama became active, sometime in the early Pleistocene epoch.

Ecology and recreation

Diverse flora exists on Mount Bailey. Starting at the lower slopes, the prominent tree type is standard pine, eventually changing to a landscape of mountain hemlock, western white pine, and Shasta fir. Bailey is a popular hiking and skiing site, due to its steep climbs and views of Diamond Lake. It is accessible from Oregon Route 230, starting at the Fox Spring trailhead. Following the Mount Bailey Trail, part of the Diamond Lake Recreational Area, hikers can see "panoramas to the northeast of Diamond Lake and Bailey's dizzying avalanche bowl". To skiers, the peak is known for its method of transportation, featuring snowcats.

Worked examples

Example 1 — a first encounter with Mount Bailey (Oregon)

Start with the simplest possible case. Write down what Mount Bailey (Oregon) 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 Mount Bailey (Oregon) 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 Mount Bailey (Oregon) 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 Mount Bailey (Oregon)

In research: Mount Bailey (Oregon) 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 Mount Bailey (Oregon) 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: Mount Bailey (Oregon) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cascade Range, Cascade Volcanoes, Dormant volcanoes, so understanding it makes those chapters shorter.
In everyday life: Look for Mount Bailey (Oregon) 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.
