Wet Canyon on Mt. GrahamWet Canyon on Mt. Graham

The Pinaleño Mountains or "Mount Graham" is a unique ecological treasure that is sacred to the San Carlos Apache. It is the tallest mountain in southern Arizona and encompasses 6 different life zones from the valley floor to its peak at 10,720 ft.Aspen atop Mt. GrahamAspen atop Mt. Graham

For decades, Apaches, scientists, conservationists, and university students have resisted the University of Arizona's decision to build several large telescopes on the mountain's summit.

Called a "Sky Island" ecosystem, the old growth forests on Mount Graham's summit are the Arizona equivalent of rainforests. The abundant springs and high altitude meadows have offered sustenance and a source of healing to desert dwelling Apaches. While frequent cloud cover makes telescope viewing marginal (Mount Graham was ranked 38th in a study of astronomical sites in the US), the cool moist characteristics of the mountain have aided the evolution of 18 different plants and animals found nowhere else in the world. Today, the construction of telescopes and resulting federal closure of the mountain top are desecrating the mountain and its irreplaceable relationship with the Apache people.


Endangered Arizona squirrel drops in numbers

The estimated number of endangered Mount Graham squirrels that make their home atop the Pinaleno Mountains in southeastern Arizona is among its lowest in the past 15 years, but biologists are hopeful the small mammals will rebound.

Environmentalists, on the other hand, aren't so optimistic. They say the species won't be on the path to recovery without a significant effort to protect their habitat in the high elevation spruce-fir forest.

Apaches oppose telescope permit renewal

By Diane Saunders, Staff Writer - 9-29-10

The White Mountain Apache Tribe is opposed to the renewal of the long-term use permit that allows the University of Arizona to operate the Mount Graham International Observatory, but the U.S. Forest Service expects the renewal process to be completed next month.

The Western Apache tribes, including the San Carlos and White Mountain tribes, consider the Mount Graham observatory site sacred. Read more »

Potential Captive Breeding Pilot Program for the Mount Graham Red Squirrel

The U.S. Fish and Wildlife Service (FWS) has prepared this draft Environmental Assessment (dEA) to analyze potential effects to physical, biological, social, and cultural resources that may result from establishing a captive breeding pilot program for the endangered Mount (Mt.) Graham red squirrel (Tamiasciurus hudsonicus grahamensis) (red squirrel or squirrel). Read more »

Squirrelly byways on Mt. Graham

By Dexter K. Oliver, Eastern AZ Courier - Contributing Columnist (Published on Sunday, June 13, 2010 9:16 AM MST)

I enjoyed reading Jon Johnson’s article “Squirrel bridges planned for Mount Graham” in the June 9 Copper Era. It’s always nice to have a good laugh during these trying times, and, luckily, the wildlife management arena in Arizona is quite often willing to provide us with such chuckles and much shaking of the head.

MGIO Forest Service Lease up for Renewal

LBT Telescope atop Mt. GrahamLBT Telescope atop Mt. GrahamThe Mt. Graham International Observatory sits on publicly owned land - specifically Forest Service land. MGIO holds a lease to that land, which needs to be renewed periodically and is up for renewal now. Please contact the Coronado Nat'l. Forest and let them know it's time to deny the MGIO lease and revegetate the top of the tallest and only Sky Island with the endangered spruce/fir life-zone and that is very sacred to the Apache.
