Mount Lemmon (O'odham : Babad Doʼag), with a summit elevation of 9,159 feet (2,792 m), [1] is the highest point in the Santa Catalina Mountains. It is located in the Coronado National Forest north of Tucson, Arizona, United States. Mount Lemmon was named for botanist Sara Plummer Lemmon, who trekked to the top of the mountain with her husband and E. O. Stratton, a local rancher, by horse and foot in 1881. [3] [4] It is reported that Mount Lemmon Ski Valley, on the mountain's northeastern side, receives 200 inches (508 cm) of snow annually. [5]

Summerhaven

Summerhaven is a small town near the top of the mountain. It is a summer residence for many but there are some year round residents. There are many small cabins most of which were rebuilt after the Aspen Fire of July 2003. [6]

Mount Lemmon Station Observatory

At the peak is the Mount Lemmon Observatory, which was formerly the site of a USAF radar base of the Air Defense Command, [7] and the building that formerly housed a military emergency radar tracking station for landing the Space Shuttle at White Sands Missile Range. Although the United States military had a presence on the mountain for several decades all their facilities have been abandoned and were given to the United States Forest Service. The area and buildings that makes up the Mount Lemmon Station Observatory are leased from the Forest Service by the University of Arizona. The telescopes on the mountain are still used for astronomical research today by organizations such as the Catalina Sky Survey, the Mount Lemmon Sky Center, [8] the University of Arizona Astronomy Camp program, [9] the University of Arizona, and the University of Minnesota. The educational resources at the top of the mountain make it a unique research and teaching destination.

Catalina Highway

The Catalina Highway, also called the Mount Lemmon Highway, as well as the Hitchcock Highway (after Frank Harris Hitchcock) runs up the Santa Catalina Mountains from the east side of Tucson up to Summerhaven, at the top of Mt. Lemmon. The beautiful, curving road is a favorite drive for tourists, for locals escaping summer's heat and cyclists, and has been recently designated as the Sky Island Parkway, part of the US National Scenic Byway system. [10]

2010 saw the inaugural running of the Mount Lemmon Marathon. [11]

Climate

The summit of the mountain is approximately twenty degrees cooler than the base. Therefore, large amounts of snow fall during the winter months, making it a cool escape and popular tourist attraction for Tucson and Phoenix inhabitants.

Fees and permits

Catalina Highway charges tolls for parking, camping, and hiking. However, the tolls are only officially charged for people who are camping. Tolls for other events, such as hiking, parking, or grilling, are a part of the honor system. Park rangers will not check for toll payments unless someone is using the park campgrounds. Anyone wishing to sightsee or travel to Summerhaven are not subjected to paying tolls.[ citation needed ]

An unpaved road to the summit on the north side of Mount Lemmon starts in Oracle, which is on Arizona Route 77 north of Tucson. It offers a secondary route to the top. This route is popular with off-road 4x4 drivers and with off-road or dual-purpose motorcyclists. This road ends at the Catalina Highway near Loma Linda. Before the Catalina Highway was built it was the only route up the mountain. [12]

The Mount Lemmon Marathon was formerly an annual marathon that takes place in the Santa Catalina Mountains near the city of Tucson, Arizona, United States. The race started near the desert floor and ended at the village of Summerhaven near the top of Mount Lemmon. It was noted for the entire course being uphill, and had an elevation gain of over 6,000 feet (1,800 m). Local television station KVOA described the race as "the only long-distance uphill race in the U.S". It had been described as the most difficult road marathon in the world. Runners ran on the General Hitchcock Scenic Byway and started the race surrounded by cacti near the floor of the Sonoran Desert, and as they climbed the mountain, runners transitioned into lush pine forests near the top of the mountain at over 8,000 feet (2,400 m) above sea level.

C/2012 F6 (Lemmon) Long-period comet discovered on 23 March 2012, by A. R. Gibbs.

C/2012 F6 (Lemmon) is a long-period comet discovered in Leo on 23 March 2012, by A. R. Gibbs using the 1.5-m reflector at the Mt. Lemmon Survey, located at the summit of Mount Lemmon in the Santa Catalina Mountains north of Tucson, Arizona, USA. Initially, the object was considered to be of asteroidal nature before later observations confirmed its cometary appearance. Comet Lemmon has a highly eccentric orbit, bringing it as close to 0.73 AU from the sun at perihelion and as far as 973 AU from the sun at aphelion. This also leads to the comet's long-period nature with an orbital period of approximately 8,000 years based on epoch 2050. The comet last reached perihelion on 24 March 2013.
