Greens Peak fog forest
Greens Peak is the highest of a set of rounded knolls sitting atop a raised highland north of Mount Baldy, in the White Mountains of Eastern Arizona. The White Mountains and surrounding terrain are part of the Springerville Volcanic Field, the second-largest such field in the country (the largest also being in Arizona, the San Francisco Volcanic Field in Northern Arizona). Greens Peak is named after Major John Green, who was a principal figure in the creation of Fort Apache (source).
The knolls that sit atop the highlands north of Mount Baldy all have a consistent round shape, usually rising about 500-800 feet above the meadows and forests below. The knolls, including Greens Peak, are apparently single-event eruption cones, or monogenetic cones. The eruptions came and went, never often enough to form into one giant mass with a sophisticated magma system.
