Ingraham Trail

Ingraham Trail 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 Ingraham Trail rather than just read about it. In short: The Ingraham Trail, officially Northwest Territories Highway 4, extends from Yellowknife, Northwest Territories to Tibbitt Lake, approximately 70 km (43 mi) east of Yellowknife. It was built in the mid-1960s as the first leg of a 'road to resources' with the original intention of encircling Great Slave Lake.

Key takeaways

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

Reference excerpt

The Ingraham Trail, officially Northwest Territories Highway 4, extends from Yellowknife, Northwest Territories to Tibbitt Lake, approximately 70 km (43 mi) east of Yellowknife. It was built in the mid-1960s as the first leg of a 'road to resources' with the original intention of encircling Great Slave Lake. The highway is designated as a northern/remote route of Canada's National Highway System. The Ingraham Trail serves as both an industrial and recreational highway. In February and March each year, the trail is the initial section of the Tibbitt to Contwoyto Winter Road to three diamond mines located 300 km (190 mi) northeast of Yellowknife. The trail is also known as Yellowknife's cottage country, with the bulk of seasonal and year-round cabins located between Cassidy Point and Prelude Lake Territorial Park. During the winter road program, B-train tractor trailers travel the road, four loads every 20 minutes, 24 hours a day. Although it serves primarily recreational activities and area residences in this lake-dotted country, after the ice break-up on Great Slave Lake, the highway is the only access to Dettah from Yellowknife. The small Dene community is about 6.5 km (4.0 mi) from Yellowknife by ice road in winter or 27 km (17 mi) using the Ingraham Trail. For about a month in late winter, a winter road to Lac de Gras is opened to trucking of mining supplies, the junction being along the Ingraham Trail. The road condition has suffered due to its frequent use by heavy trucks. This is shown on the first season of the American reality television series, Ice Road Truckers, which aired on History. The Tibbitt to Contwoyto Winter Road also extends from the end of the Ingraham Trail to Contwoyto Lake in Nunavut, forming Nunavut's only connection to the road network in the rest of Canada. The Ingraham Trail is named after Vic Ingraham, a pioneer Yellowknife businessman of the 1930s–40s. Yellowknife has experienced an aurora borealis tourism boom the last few years and the Ingraham Trail is the prime viewing location. It is common to come across aurora rush after midnight during the peak aurora season, November to March.

Details

Since January 2014, the road bypasses Giant Mine through a realignment that originates off Highway 3, approximately 2 km (1.2 mi) from the Old Airport Road turnoff. At 7.6 km (4.7 mi) the road crosses the Yellowknife River followed by the Dettah turnoff at 9.8 km (6.1 mi). After this the road passes several territorial parks:

Yellowknife River Territorial Park (7.7 km (4.8 mi)) Dettah turnoff (9.8 km (6.1 mi)) Prosperous Lake Territorial Park (19.7 km (12.2 mi)) Madeline Lake Territorial Park (24 km (15 mi)) Pontoon Lake Territorial Park (26.4 km (16.4 mi)) Prelude Lake Territorial Park (28 km (17 mi) Hidden Lake Territorial Park (44 km (27 mi)) Powder Point Day Use Area 44 km (27 mi)) Cameron River Falls Day Use Area/Hiking Trail Access (45.8 km (28.5 mi)) Cameron River Crossing (54.5 km (33.9 mi)) Reid Lake Territorial Park (59 km (37 mi)) before reaching Tibbitt Lake (69.2 km (43.0 mi)). The trail is chipsealed to Reid Lake, leaving the last 10 km (6.2 mi) as gravel.

Worked examples

Example 1 — a first encounter with Ingraham Trail

Start with the simplest possible case. Write down what Ingraham Trail 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 Ingraham 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 Ingraham 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 Ingraham Trail

In research: Ingraham Trail 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 Ingraham 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: Ingraham Trail is common in secondary-school and first-year university syllabi. It links to neighbouring topics Gravel roads, Northwest Territories territorial highways, so understanding it makes those chapters shorter.
In everyday life: Look for Ingraham 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.
