Tamanowas Rock

Tamanowas Rock is a 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 Tamanowas Rock rather than just read about it. In short: Tamanowas Rock (Klallam: t̕əménəwəs) (also spelled Tamanous), also called Chimacum Rock, is a 150-foot (46 m) high rock with caves and crevices that lies in a forest adjacent to Anderson Lake State Park, near Port Townsend, Washington. It is a sacred site to the Coast Salish peoples of the Pacific Northwest and a pilgrimage site.

Key takeaways

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

Reference excerpt

Tamanowas Rock (Klallam: t̕əménəwəs) (also spelled Tamanous), also called Chimacum Rock, is a 150-foot (46 m) high rock with caves and crevices that lies in a forest adjacent to Anderson Lake State Park, near Port Townsend, Washington. It is a sacred site to the Coast Salish peoples of the Pacific Northwest and a pilgrimage site. The rock was listed on the National Register of Historic Places in 2015.

History Tamanowas Rock is said to have first been used 10,000 years ago by the Chimakum (or Chemacum) people, leading to its alternate name "Chimacum Rock", whose name is also found in other local geographic features. In accordance with legend, it may have been used as a refuge from the tsunami caused by the 1700 Cascadia earthquake, and earlier as a lookout for hunting now-extinct mastodon. "Tamanowas" means "spirit power" in the Klallam language.

Preservation The site is either a registered archaeological site, or nominated to become one with the Washington State Department of Archaeology. In 2013, the rock was purchased with 62 acres (25 ha) of surrounding land by the Jamestown S'Klallam Tribe for preservation, at the end of a series of loans and purchases by organizations including Washington State Parks, Bullitt Foundation and Jefferson Land Trust, that started in 2009. The land was added to an existing 22-acre purchase by the tribe. Prior to this, it was a rock climbing site, a practice which was ended when the S'Klallam Tribe took ownership.

Desecration In 2014, the rock was desecrated with graffiti, gaining national and international attention.

Geology

The mineral composition is Eocene subaerial adakitic lava and lava breccia. Dikes of similar composition exist in the Blue Hills near Bremerton 60 km away, both thought to be created by subduction of the Kula-Farallon Ridge beneath North America. They may be related by being part of a magmatic arc , they may be two isolated volcanic centers, or they may have been created at a single center and displaced along a fault (see Puget Sound faults).

Worked examples

Example 1 — a first encounter with Tamanowas Rock

Start with the simplest possible case. Write down what Tamanowas Rock claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Tamanowas Rock 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 Tamanowas Rock 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 Tamanowas Rock

In research: Tamanowas Rock appears in 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 Tamanowas Rock 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: Tamanowas Rock is common in secondary-school and first-year university syllabi. It links to neighbouring topics Archaeological sites in Washington (state), Coast Salish art and artifacts, Landforms of Jefferson County, Washington, so understanding it makes those chapters shorter.
In everyday life: Look for Tamanowas Rock 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.
