Tiger Mountain is a mountain in the U.S. state of Washington.

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.

Washington (state) State of the United States of America

Washington, officially the State of Washington, is a state in the Pacific Northwest region of the United States. Named for George Washington, the first president of the United States, the state was made out of the western part of the Washington Territory, which was ceded by Britain in 1846 in accordance with the Oregon Treaty in the settlement of the Oregon boundary dispute. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle.



The mountain has six peaks in the center of the Issaquah Alps, forming a 13,500-acre (55 km2) triangle between Interstate 90 (I-90) on the north, Issaquah-Hobart Road on the southwest, and State Route 18 (SR 18) on the southeast. Immediately to the west is Squak Mountain followed by Cougar Mountain, while to the southeast are McDonald and Taylor Mountains, and Rattlesnake Ridge.

Issaquah Alps

The Issaquah Alps is the unofficial name for the highlands near Issaquah, Washington, a suburb of Seattle, including Cougar Mountain, Squak Mountain, Tiger Mountain, Taylor Mountain, Rattlesnake Ridge, Rattlesnake Mountain, and Grand Ridge. The term was invented in 1977 by noted nature author Harvey Manning within the pages of his trail guidebook Footsore 1, elevating their status from foothills to "Alps" to advocate preservation. Manning himself lived on a developed section of Cougar Mountain in his "200 meter hut".

Issaquah, Washington City in Washington, United States

Issaquah is a city in King County, Washington, United States. The population was 30,434 at the 2010 census and an estimated 39,378 in 2018. Located in a valley and bisected by Interstate 90, the city is bordered by the Sammamish Plateau to the north and the "Issaquah Alps" to the south.

Hobart, Washington Census-designated place in Washington, United States

Hobart is an unincorporated community and census-designated place (CDP) in King County, Washington, United States. The population was 6,221 at the 2010 census.

Tiger Mountain State Forest was established in 1981. In 1989, the entire Issaquah Plateau in the northwest corner was designated as a conservation area, the West Tiger Mountain Natural Resources Conservation Area, accessed by a large trailhead at Exit 20 on I-90.

The most crowded trail leads to the bald summit of West Tiger #3, with a panoramic view of Seattle and points to the south and east. It is a 6.2-mile (10.0 km) hike, round-trip, with an elevation change of about 2,000 feet (610 m). The nearby peaks of West Tiger #2 and West Tiger #1 provide essentially the same view, but with fewer obstructions.

Seattle City in Washington, United States

Seattle is a seaport city on the West Coast of the United States. It is the seat of King County, Washington. With an estimated 744,955 residents as of 2018, Seattle is the largest city in both the state of Washington and the Pacific Northwest region of North America. According to U.S. Census data released in 2018, the Seattle metropolitan area's population stands at 3.94 million, and ranks as the 15th largest in the United States. In July 2013, it was the fastest-growing major city in the United States and remained in the top 5 in May 2015 with an annual growth rate of 2.1%. In July 2016, Seattle was again the fastest-growing major U.S. city, with a 3.1% annual growth rate. Seattle is the northernmost large city in the United States.

Poo Poo Point, a bare shoulder of West Tiger Mountain, is a bare ridge on the west side of Tiger Mountain. The point is named for the sound the steam whistles would make when signaling loggers. The point is a popular launching point for paragliding and hang gliding. The point is reached by the Chirico Trail, which starts at the landing zone for the hang gliders and paragliders in a field adjacent to the Issaquah-Hobart Road, or by taking the High School Trail which begins on 2nd Avenue just south of Issaquah High School. Many people fly year-round (weather permitting) and have flown cross-country flights exceeding 75 miles (121 km). [3]

A steam whistle is a device used to produce sound with the aid of live steam, which acts as a vibrating system.

Paragliding sailing with a paraglider

Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure. The pilot sits in a harness suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside.

Hang gliding air sport or recreational activity

Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame.

State Route 18 runs between Tiger and Taylor mountains, reaching an elevation of 1,375 feet (419 m). This stretch of the highway is commonly referred to as the "Tiger Mountain Summit" in local traffic reports. Another major trailhead is located at this summit. The trail provides access to South Tiger Mountain with limited views, Middle Tiger Mountain with a 45-degree window looking down on the Cedar Hills Landfill, and East Tiger Mountain with a panoramic view south toward Mount Rainier.

Mount Rainier stratovolcano in the U.S. state of Washington

Mount Rainier, also known as Tahoma or Tacoma, is a large active stratovolcano located 59 miles (95 km) south-southeast of Seattle, in the Mount Rainier National Park. With a summit elevation of 14,411 ft (4,392 m), it is the highest mountain in the U.S. state of Washington, and of the Cascade Range of the Pacific Northwest, it is the most topographically prominent mountain in the continental United States and the first in the Cascade Volcanic Arc.

Many trails on Tiger Mountain have wide beds and slope very gently because they are built on the remnants of 1920s logging railroads, long after the rails and crossties were salvaged in the Great Depression. Near Middle Tiger Mountain is the site of a fatal 1924 train wreck where artifacts can still be seen.

In the most remote part of the forest, 15 Mile Creek arises in the pass between East and West Tiger. The creek carves a miniature "Grand Canyon" through sandstone.

Much of Tiger Mountain is owned or managed by the Washington State Department of Natural Resources. [4]
