## History

White Anglo-Americans originally used the area of Summerhaven when the U.S. Army at Fort Lowell in Tucson put a military camp there in its defense against the Apache in the 1870s and 1880s. As to white settlement of the vicinity, the Ransier School in Carter Canyon, run by Lydia Ransier and 'Auntie' Broadbent, had two cabins, the larger log one being built in 1912, "one of the oldest cabins on the mountain."
According to historian David Leighton, Summerhaven at one point had the highest golf links in the world. He wrote, "F.E.A Kimball (namesake of Mount Kimball), head of the Summerhaven Land and Improvement Co. on Mount Lemmon, constructed a six-hole golf links. The course was on 50 acres, a mix of Forest Service and private land, with two trout streams running through the acreage. The links were about 7,800 feet above sea level, making it the highest golf course in the world...."

## Tourism and recreation

Summerhaven is a popular tourist destination. Several small shops in Summerhaven attract visitors. In the winter, residents from lower elevations travel to Summerhaven, when the Catalina Highway is open, to enjoy the snow. Also during the summer, the same residents will frequent the area to get away from the heat. Because of the elevation difference between the Tucson area (5,000–6,000 feet), the temperature in Summerhaven will be anywhere from 15–30 degrees F cooler depending on weather patterns, which usually makes it a very comfortable place to be compared to the hot desert heat in the summer time.
October 2010 saw the inaugural running of the Mount Lemmon Marathon, in which nearly 800 participants finished the race from near the start of the Catalina Highway up to Summerhaven.
