| Location | Chelan County, Washington, United States |
Cardinal Peak is the highest peak of the Chelan Mountains, a subrange of the Cascade Range in the U.S. state of Washington. It is located in Wenatchee National Forest at the head of the Entiat River drainage basin, in Chelan County. To the west and north, streams flow into Lake Chelan. Cardinal Peak is less than 5 miles (8.0 km) from the lake and rises 7,500 feet (2,300 m) above the lakeshore. [3] At 8,595 feet (2,620 m) high, it is the 49th highest peak in Washington. Its 2,070-foot (630 m) prominence ranks 132nd in the state. [1] [4]
The Chelan Mountains, or Chelan Range is a mountain range in the U.S. state of Washington. Located west of the Columbia River, north of the Entiat River, and south of Lake Chelan, the range is part of the North Cascades section of the Cascade Range. The Chelan Range is about 40 mi (64 km) long northwest to southeast and about 8 mi (13 km) wide, southwest to northeast.
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).
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.

The rocks of Cardinal Peak are mainly granodiorite and hornblende quartz diorite, minerals of the Cardinal Peak pluton. [3]
Granodiorite is a phaneritic-textured intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar. According to the QAPF diagram, granodiorite has a greater than 20% quartz by volume, and between 65% to 90% of the feldspar is plagioclase. A greater amount of plagioclase would designate the rock as tonalite.
Hornblende is a complex inosilicate series of minerals. It is not a recognized mineral in its own right, but the name is used as a general or field term, to refer to a dark amphibole.
Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.
