- Phanerite (Wikipedia)
A phanerite is an igneous rock whose microstructure is made up of crystals large enough to be distinguished with the unaided human eye. In contrast, the crystals in an aphanitic rock are too fine-grained to be identifiable. Phaneritic texture forms when magma deep underground in the plutonic environment cools slowly, giving the crystals time to grow.
- Gifford Pinchot National Forest (Wikipedia)
Gifford Pinchot National Forest is a National Forest located in southern Washington, managed by the United States Forest Service. With an area of 1.32 million acres (5,300 km2), it extends 116 km (72 mi) along the western slopes of Cascade Range from Mount Rainier National Park to the Columbia River. The forest straddles the crest of the South Cascades of Washington State, spread out over broad old-growth forests, high mountain meadows, several glaciers, and numerous volcanic peaks. The forest’s highest point is at 12,276 ft (3,742 m) at the top of Mount Adams, the second-tallest volcano in the state after Rainier. Often found abbreviated GPNF on maps and in texts, it includes the 110,000-acre (450 km2) Mount St. Helens National Volcanic Monument, established by Congress in 1982.
