Eureka Creek is a tributary of Baker Creek in the U.S. state of Alaska. Other Baker tributaries in the vicinity of Eureka Creek include Thanksgiving, Gold Run, and Pioneer creeks with Seattle Junior Creek a tributary of Pioneer. [1]

Tributary stream or river that flows into a main stem river or lake

A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean.

Baker Creek is a right bank tributary of the Tanana River in the U.S. state of Alaska. Baker Creek tributaries include Thanksgiving, Gold Run, Eureka, and Pioneer creeks; Seattle Junior Creek is a tributary of Pioneer Creek. The Baker Creek diggings of the early 20th century were situated approximately 30 miles (48 km) south of Rampart.

U.S. state constituent political entity of the United States

In the United States, a state is a constituent political entity, of which there are currently 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory and shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders. Four states use the term commonwealth rather than state in their full official names.

Geography

Eureka Creek flows southwest along the foot of the Baker-Minook divide. It runs in a straight southwest course for about 4.5 miles (7.2 km), then turns and runs south 2.5 miles (4.0 km) to its junction with Pioneer Creek. It has a number of small tributaries from the northwest side, but none from the southeast. The largest is Boston Creek, about 2 miles (3.2 km) long, which joins Eureka Creek at its bend. The other tributaries are rills. Eureka is a small creek carrying barely a sluicehead of water above the mouth of Boston Creek during the ordinary seasons. The valley slopes gently to the divide on the northwest side, but on the southeast side the slope is almost precipitous, rising 400–600 feet (120–180 m) above the valley. The creek flows close to the foot of the steeper side. [2]

Minook Creek is a waterway in the U.S. state of Alaska. It is named after John Mynook Pavaloff, a half-Russian/half-native Alaskan, who found gold in the river's valley in 1894.

Rill topographic feature

In hillslope geomorphology, a rill is a shallow channel cut into soil by the erosive action of flowing water. Similar but smaller incised channels are known as microrills; larger incised channels are known as gullies.

Sluice A water channel controlled at its head by a gate

A sluice is a water channel controlled at its head by a gate. A mill race, leet, flume, penstock or lade is a sluice channelling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry.

The gravels of the creek are not very worn, characteristic of weak streams, and have been left for a considerable distance, in places at least 500 feet (150 m), up the slope of the hill as the stream bed has moved to the southeast. The bench gravels are made up entirely of country rocks. The deposit varies in thickness from 5–18 feet (1.5–5.5 m), and the overlying muck varies from between 0–8 feet (0.0–2.4 m), the distribution being irregular. The total thickness varies from 5–10 feet (1.5–3.0 m). The gravel contains a considerable amount of very sticky clay. The clay seems to come from the decomposition of both the grit and the slates.

History

Gold was first discovered on Eureka Creek in February 1899. [2]

Yukon River river in the Yukon territory of Canada

The Yukon River is a major watercourse of northwestern North America. The river's source is in British Columbia, Canada, from which it flows through the Canadian Yukon Territory. The lower half of the river lies in the U.S. state of Alaska. The river is 3,190 kilometres (1,980 mi) long and empties into the Bering Sea at the Yukon–Kuskokwim Delta. The average flow is 6,430 m3/s (227,000 ft3/s). The total drainage area is 832,700 km2 (321,500 mi2), of which 323,800 km2 (126,300 mi2) is in Canada. The total area is more than 25% larger than Texas or Alberta.

Steamboats of the Yukon River

Steamboats on the Yukon River played a role in the development of Alaska and Yukon. Access to the interior of Alaska and Yukon was hindered by large mountains and distance, but the wide Yukon River provided a feasible route. The first steamers on the lower Yukon River were work boats for the Collins Overland Telegraph in 1866 or 1867, with a small steamer called Wilder. The mouth of the Yukon River is far to the west at St. Michael and a journey from Seattle or San Francisco covered some 4,000 miles (6,400 km).

Elbridge Truman Barnette, Yukon riverboat captain, banker, and swindler, founded the city of Fairbanks, Alaska, and served as its first mayor.

Rampart Dam proposed dam of the Yukon River

A project proposed in 1954 by the U.S. Army Corps of Engineers to dam the Yukon River in Alaska for hydroelectric power called Rampart Dam or Rampart Canyon Dam. Planned for Rampart Canyon just 31 miles (50 km) southwest of the village of Rampart, Alaska and about 105 miles (169 km) west-northwest of Fairbanks, Alaska, the resulting dam would have created a lake roughly the size of Lake Erie, making it the largest man-made reservoir in the world. The plan for the dam itself called for a concrete structure 530 feet (162 m) high with a top length of about 4,700 feet (1,430 m). The proposed power facilities would have consistently generated between 3.5 and 5 gigawatts of electricity, based on the flow of the river as it differs between winter and summer.

Mount Prindle mountain in United States of America

Mount Prindle is a granitic mountain in the Yukon–Tanana Uplands, and is located approximately 45 miles (72 km) north-northeast of Fairbanks, Alaska. The plutons that form the core of the Mount Prindle massif are Late Cretaceous or early Tertiary age. These plutons intruded older metamorphic rocks. Mount Prindle exhibits classic glacial landforms, unlike most of the surrounding Yukon–Tanana Uplands. It is in the Circle Mining District and many of the surrounding creeks have been or are being mined for placer gold. The area has also been prospected for tin and rare earth minerals. Mine roads and hiking trails provide access to the mountain. A 900 feet (270 m) granite wall on an eastern spur of the massif is an attraction for rock climbers.
