Gulf Hagas

Gulf Hagas 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 Gulf Hagas rather than just read about it. In short: Gulf Hagas is a gorge located in the mountains of northern Maine woods and is often referred to as the Grand Canyon of Maine. The West Branch of the Pleasant River cuts through the earth for three miles creating a vertically walled slate gorge with numerous waterfalls.

Reference excerpt

Gulf Hagas is a gorge located in the mountains of northern Maine woods and is often referred to as the Grand Canyon of Maine. The West Branch of the Pleasant River cuts through the earth for three miles creating a vertically walled slate gorge with numerous waterfalls. A trail follows the rim of the canyon offering hikers views of the falls and its geology. The gorge is 3 miles (4.8 km) long; the river drops 370 feet (110 m) in this distance boasting 130 feet (40 m) walls. Gulf Hagas is one of 14 National Natural Landmarks in the State of Maine, and is open to the public for a fee during the regular season.

Where Gulf Hagas is part of the Appalachian Trail (AT) Corridor. For a short distance the Gulf Hagas Rim Trail follows the AT, a 2,200 miles (3,500 km) hiking trail extending from Georgia to Maine. The section of the AT which goes through Gulf Hagas is called the Hundred-Mile Wilderness. This is the final 100 miles (160 km) of the AT and is viewed by many as the most remote and difficult portion. Most people access Gulf Hagas by driving through Katahdin Iron Works, a State Park and historic site where iron ore was once smelted. Gulf Hagas is 90 miles (140 km), 1 hour and 20 minute drive from Bangor, Maine. From Portland, Maine the drive is a 3 hour and 40 minute, 172 miles (277 km) trip.

History Logs were once driven through the gorge to provide fuel for the smelting operations which took place at Katahdin Iron Works. Later, pulp wood used to make paper was floated through the Gulf. A few spots within the gorge were as narrow as 8 feet (2.4 m) and were referred to as the Jaws. These spots caused log jams and were widened by the log drivers using dynamite. Log drivers are responsible for naming most of the major waterfalls and rapids in Gulf Hagas. The Gulf was previously owned by the paper companies, Great Northern Paper Company and Sappi. Gulf Hagas was designated a National Natural Scenic Landmark in 1969 and landowners agreed to preserve 500 acres (200 ha) of land including Gulf Hagas. Gulf Hagas became part of Appalachian Trail Corridor, owned by the National Park Service, in 1985. The Maine Appalachian Trail Club, consisting of mostly volunteers, maintains the Gulf's system of trails.

Geology and geography The bedrock which forms Gulf Hagas is slate, part of the Carrabassett formation. 400 million years ago converging plates forced land upward, displacing the Iapetus Ocean. Mud deposits remained, which were heated, compressed, and crystallized to form slate. Slate has sharp, angular edges when it fractures but is polished smooth by the action of erosion. This is evident deep in the canyon where the gorge walls are smooth and vertical. The swirling motion of water and pebbles creates potholes in the gorge, spherical depressions in the rock. Gulf Hagas may have been created towards the end of the last ice age when an ice-dammed lake gave way and sent huge volumes of water through the area, carving the Gulf.

Flora and fauna The Gulf Hagas Rim Trail passes through The Hermitage, one of the few remaining stands of virgin old growth forest in New England. Giant eastern white pine trees adorn this area and can be seen as tall as 150 feet (46 m), with diameters sometimes spanning 10 feet (3.0 m). The rim trail is characterized by pine trees. Black spruce, eastern hemlock, balsam fir and eastern white pine trees are the most common. Moose are frequently seen in the area along with white-tailed deer and snowshoe hare. Within the gorge, Brook Trout are abundant.

Myth and lore

Native Americans certainly lived, hunted, and fished around Gulf Hagas. Gravesites belonging to the mysterious "Red Paint People" have been found in the area. Red ochre, an impure form of iron ore readily available in the area was used by the Red Paint People on their tools, skin and during burials. Grave sites were lined with the red ochre which preserved bodies of the deceased. Burial grounds belonging to Red Paint People have been discovered dating back 7,500 years. Simon Garew, the Legend of the Gulf, would travel to the gorge with his dog each year to hunt and fish. His secret reason for visiting the gorge is described in a poem; here is an excerpt from Simon Garfew A Legend of Gulf Glen:

"The Great Spirit comes to the face in the rock, The moon when the leaves grow red; And when the round moon shines upon it, Shines into the Gulf at night, Shines full and fair upon it, Making it plain and white, - Whoever waits there, with fasting, Below the strong face, With a deer's blood for offering Always finds pardon and peace." Simon ventured into the canyon one fall and was never seen again after a storm filled the gorge with water. All that was left was his dog who wouldn't leave the Gulf without him.

Hiking Hiking along the Gulf Hagas Rim Trail is the most popular option for hikers who wish to view the gorge. Hikers should be well prepared and get an early start; the hike is 8 miles (13 km) long and takes up to 8 hours. Those seeking a more moderate hike may consider visiting The Hermitage and Gulf Hagas Brook, which is a 4 miles (6.4 km) round trip. There is no camping allowed in Gulf Hagas, but camping is available nearby provided by KI Jo-Mary. Fires are not allowed in Gulf Hagas. Water can occasionally be found along the Rim Trail but should be treated for contaminants before consumption. Anything brought into Gulf Hagas should be brought out; this a primitive area, there are no trash disposal services. Black-flies and mosquitoes can be thick in the spring and summer months. Insect repellent and long-sleeved clothing is advised. The weather in Maine can change quickly and hikers should be prepared for any type of weather.

Worked examples

Example 1 — a first encounter with Gulf Hagas

Start with the simplest possible case. Write down what Gulf Hagas 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 Gulf Hagas 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 Gulf Hagas 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 Gulf Hagas

In research: Gulf Hagas 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 Gulf Hagas 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: Gulf Hagas is common in secondary-school and first-year university syllabi. It links to neighbouring topics Canyons and gorges of the United States, Landforms of Piscataquis County, Maine, National Natural Landmarks in Maine, so understanding it makes those chapters shorter.
In everyday life: Look for Gulf Hagas 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.
