Navajo meridian and baseline

Navajo meridian and baseline 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 Navajo meridian and baseline rather than just read about it. In short: The Navajo meridian, established in 1869, is one of the two principal meridians for Arizona, the other being the Gila and Salt River meridian. Its initial point was stated as latitude 35° 45' north, longitude 108° 32' 45" west from Greenwich, but has been revised as 35°44′56″N 108°31′59″W The Navajo meridian and baseline were used to set townships and ranges in a special survey for the original Navajo Reservation, a…

Key takeaways

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

Reference excerpt

The Navajo meridian, established in 1869, is one of the two principal meridians for Arizona, the other being the Gila and Salt River meridian. Its initial point was stated as latitude 35° 45' north, longitude 108° 32' 45" west from Greenwich, but has been revised as 35°44′56″N 108°31′59″W The Navajo meridian and baseline were used to set townships and ranges in a special survey for the original Navajo Reservation, and was set at the eastern boundary of that reservation. The Arizona lands surveyed using the Navajo meridian and baseline were ranges six west to ten west and townships one north to fourteen north, and included Canyon de Chelly National Monument. While the above-mentioned Arizona lands still reference the Navajo meridian and baseline, in New Mexico the surveys of lands originally surveyed under it were canceled in 1936, and have since been resurveyed using the New Mexico meridian and baseline. In Arizona, only the portions of the Navajo Reservation that are east of the Hopi Reservation were surveyed using the Navajo meridian and baseline.

Worked examples

Example 1 — a first encounter with Navajo meridian and baseline

Start with the simplest possible case. Write down what Navajo meridian and baseline 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 Navajo meridian and baseline 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 Navajo meridian and baseline 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 Navajo meridian and baseline

In research: Navajo meridian and baseline 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 Navajo meridian and baseline 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: Navajo meridian and baseline is common in secondary-school and first-year university syllabi. It links to neighbouring topics Geography of Arizona, Meridians (geography), Meridians and base lines of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Navajo meridian and baseline 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.
