Puget Sound is a sound on the northwestern coast of the U.S. state of Washington. It is a complex estuarine system of interconnected marine waterways and basins. A part of the Salish Sea, Puget Sound has one major and two minor connections to the Strait of Juan de Fuca, which in turn connects to the open Pacific Ocean. The major connection is Admiralty Inlet; the minor connections are Deception Pass and the Swinomish Channel.
Door County is the easternmost county in the U.S. state of Wisconsin. As of the 2020 census, the population was 30,066. Its county seat is Sturgeon Bay.
Lake Washington is a large freshwater lake adjacent to the city of Seattle, Washington, United States. It is the largest lake in King County and the second largest natural lake in the state of Washington, after Lake Chelan. It borders the cities of Seattle on the west, Bellevue and Kirkland on the east, Renton on the south, and Kenmore on the north, and encloses Mercer Island. The lake is fed by the Sammamish River at its north end and the Cedar River at its south.
The Klamath Mountains are a rugged and lightly-populated mountain range in northwestern California and southwestern Oregon in the western United States. As a mountain system within both the greater Pacific Coast Ranges and the California Coast Ranges, the Klamath Mountains have a varied geology, with substantial areas of serpentinite and marble, and a climate characterized by moderately cold winters with very heavy snowfall and warm, very dry summers with limited rainfall, especially in the south. As a consequence of the geology and soil types, the mountains harbor several endemic or near-endemic trees, forming one of the largest collections of conifers in the world. The mountains are also home to a diverse array of fish and animal species, including black bears, large cats, owls, eagles, and several species of Pacific salmon. Millions of acres in the mountains are managed by the United States Forest Service. The northernmost and largest sub-range of the Klamath Mountains are the Siskiyou Mountains.
The Kankakee River is a tributary of the Illinois River, approximately 133 miles (214 km) long, in the Central Corn Belt Plains of northwestern Indiana and northeastern Illinois in the United States. At one time, the river drained one of the largest wetlands in North America and furnished a significant portage between the Great Lakes and the Mississippi River. Significantly altered from its original channel, it flows through a primarily rural farming region of reclaimed cropland, south of Lake Michigan.
Lake Chelan is a narrow, 50.5 mi (81.3 km) long lake in Chelan County, north-central Washington state, U.S. It is an overdeepened lake and resembles a fjord, with an average width of 1.3 mi (2.1 km). Near its upper end, the lake surface lies more than 6,600 ft (2,000 m) below peaks less than 3 mi (4.8 km) away. Before 1927, Lake Chelan was the largest natural lake in the state in terms of both surface area and water volume. Upon the completion of Lake Chelan Dam in 1927, the elevation of the lake was increased by 21 ft (6.4 m) to its present maximum-capacity elevation of 1,100 ft (340 m).
Alta Lake State Park is a public recreation area located two miles (3.2 km) southwest of Pateros, Washington, at the northern end of 220-acre (89 ha) Alta Lake, in the mountainous northwest interior of the state. The 181-acre (73 ha) state park and adjacent lake lie beneath towering stone cliffs, formed by glaciation, that rise 1000 feet above the valley floor, and carry on up to the top of Old Goat Mountain which sits 4200 ft above the park. A two-mile-long (3 km) road leading to the park, Alta Lake Road, intersects State Route 153, which runs along the Methow River. The park is managed by the Washington State Parks and Recreation Commission.
Hickory Run State Park is a 15,990-acre (6,471 ha) Pennsylvania state park in Kidder and Penn Forest Townships in Carbon County, Pennsylvania in the United States. The park is spread across the Pocono Mountains. The park is easily accessible from Interstate 476 and Interstate 80.
The geology of Minnesota comprises the rock, minerals, and soils of the U.S. state of Minnesota, including their formation, development, distribution, and condition.
State Route 169 (SR 169) is a state highway in the U.S. state of Washington, located entirely within King County. It runs 25 miles (40 km) from Enumclaw to Renton, passing through Black Diamond and Maple Valley. The highway, also known as the Maple Valley Highway, functions as a major rural and suburban route for the southeastern Seattle metropolitan area and connects several highways, including SR 410, SR 18, and Interstate 405 (I-405).
Wisconsin, a state in the Midwestern United States, has a vast and diverse geography famous for its landforms created by glaciers during the Wisconsin glaciation 17,000 years ago. The state can be generally divided into five geographic regions—Lake Superior Lowland, Northern Highland, Central Plain, Eastern Ridges & Lowlands, and Western Upland. The southwestern part of the state, which was not covered by glaciers during the most recent ice age, is known as the Driftless Area. The Wisconsin glaciation formed the Wisconsin Dells, Devil's Lake, and the Baraboo Range. A number of areas are protected in the state, including Devil's Lake State Park, the Apostle Islands National Lakeshore, and the Chequamegon–Nicolet National Forest.
The Turtle-Flambeau Flowage is a 12,942 acres (52.37 km2) lake in Iron County, Wisconsin. It has a maximum depth of 15 meters and is the seventh largest lake in the state of Wisconsin by surface area. The flowage is home to unique wetland patterns and plant species as well as several species of sport and game fish, including musky, panfish, largemouth bass, smallmouth bass, northern pike, walleye and sturgeon. The lake's water clarity is low, but can vary in different locations. Fishing, camping, boating, and hunting are popular activities on the flowage, and Ojibwe people traditionally harvest fish and game on the lake. Environmental concerns on the flowage include mercury contamination, algal blooms, and several types of invasive species.
Fossil Lake is a dry lakebed in the remote high desert country of northern Lake County in the U.S. state of Oregon. During the Pleistocene epoch, Fossil Lake and the surrounding basin were covered by an ancient lake. Numerous animals used the lake's resources. Over time, the remains of many of these animals became fossilized in the lake sediments. As a result, Fossil Lake has been an important site for fossil collection and scientific study for well over a century. Over the years, paleontologists have found the fossil remains of numerous mammals as well as bird and fish species there. Some of these fossils are 2 million years old.
The Blue Hills just west of Bremerton, Washington, also called the Bremerton Hills, Bald Hills, and Wildcat Hills, consist of Gold Mountain, Green Mountain, and several informally named hills. Reaching an elevation of 1761 feet, a thousand feet above the glacial till that fills the Puget Lowland, they form a prominent landmark visible around the region. They are formed of uplifted blocks of marine basalts, the steep-walled canyons between the various summits being the fissures between the blocks. In addition to Gold Mountain and Green Mountain are several other prominent peaks unofficially named according to their elevation :
Glacial erratic boulders of King County are large glacial erratic boulders of rock which were moved into King County, Washington by glacial action during previous ice ages.
Hills in the Puget Lowland, between the Cascades and the Olympic Mountains, including the entire Seattle metropolitan area, are generally between 350–450 feet (110–140 m) and rarely more than 500 feet (150 m) above sea level. Hills are often notable geologically and for social reasons, such as the seven hills of Seattle.
The Portage Escarpment is a major landform in the U.S. states of Ohio, Pennsylvania, and New York which marks the boundary between the Till Plains to the north and west and the Appalachian Plateau to the east and south. The escarpment is the defining geological feature of New York's Finger Lakes region. Its proximity to Lake Erie creates a narrow but easily traveled route between upstate New York and the Midwest. Extensive industrial and residential development occurred along this route.
The Defiance Moraine was deposited about 14,800 years ago during the late Wisconsin glaciation and spans the northern portion of the state of Ohio from Defiance, Ohio in the west to near Pymatuning Reservoir in the east.
Douglas Creek is a creek in Douglas County, Washington. It rises in Douglas County, flows through Moses Coulee then empties to Wanapum Lake on the Columbia River. The course of the creek through Moses Coulee displays an "outdoor geologic laboratory" exhibiting basalt formations and relics of the Missoula floods of the last ice age. The watershed of Douglas Creek proper covers 132,056 acres (53,441 ha), about 11% of the county, but including McCarteny Creek the entire Moses Coulee drainage is 1,000 square miles (2,600 km2) or a little more than half of the county. The creek's flow reaches the Columbia River "during storm water runoff events", otherwise being absorbed into the aquifer.
