Mount Elden or Elden Mountain (Hopi: Hovi'itstuyqa) is located in central Coconino County northeast of Flagstaff, Arizona. It takes its name from one of the region's earliest Anglo settlers, John Elden, who, along with his family, established a homestead on the mountain's lower slopes and grazed sheep on the open grasslands below during the late 19th century.[3]
The mountain's exposed, rocky slopes are a dominant feature from almost any part of the city of Flagstaff, rising steeply nearly 2,400 feet (730 m) to an elevation of 9,301 feet (2,835 m). Much of the vegetation on the southern and southeastern slopes of the mountain was destroyed by the human-caused Radio Fire in 1977 which burned 4,600 acres (1,900 ha).[4]
Despite its rugged appearance, steep relief, and nearly 15 square miles (40 km2) of surface area,[5] Mount Elden is easily accessible via an extensive, well-developed road and non-motorized trail system that is part of the Coconino National Forest.
Mount Elden is one of six hundred volcanoes that dot the San Francisco volcanic field in Northern Arizona. It is currently dormant with the likelihood of eruption in the near future being believed to be extremely remote.[6]
Geology
[edit]Mount Elden is one of five large peripheral silicic volcanic features within the greater San Francisco Peaks volcanic system (part of the San Francisco volcanic field) which include the nearby Dry Lake Hills, the Hochderffer and White Horse Hills to the northwest, and O'Leary Peak to the northeast.[7] Because these features developed within close proximity of the San Francisco Mountain strato-volcano there is a strong likelihood that each is a geologic subsidiary of the larger mountain.[5]
Geologically, Mount Elden is a lava dome composed almost entirely of dacitic lava flows which emerged from several vents. These features emerged as intrusive emplacements within sedimentary blocks or as viscous extrusive flows in which the younger flows partially covered the older, lower flows. Geologic evidence suggests that the eruption of the mountain, which occurred at linear vents along regional faults, was a non-explosive event that took place during several flow sequences. Likewise, because of the high viscosity of the dacite, it is likely that the mountain formed in the short period of a few months' time.[5] The mountain's overlapping flows commonly take lobe-like shapes which display a variety of flow characteristics and features including concentric benches, spires, ramping shear fractures, longitudinal tension fractures, and conjugate shear fractures.[7]
Positioned within the central part of Mount Elden, on the mountain's eastern and northwestern flanks, are two sedimentary blocks. Both of these blocks display characteristics of uplift that most likely occurred as dacitic magma intruded into the sedimentary strata at a shallow depth and uplifted the layers, causing them to dip away from the mountain.[5] These blocks of sedimentary material are unique to the mountain, which otherwise is uniformly composed of silicic dacite.
Contemporary history
[edit]![John Elden home-site historical marker](http://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/John_Eldon_Home-site_Historical_Marker.jpg/220px-John_Eldon_Home-site_Historical_Marker.jpg)
John Elden, the settler for whom Mount Elden bears its name, settled at the base of what is today Mount Elden in 1877 to raise sheep near a natural spring, now referred to as Elden Springs.[8] The home-site today lies within the Kaibab National Forest and bears a National Forest historical marker just north of the City of Flagstaff, Arizona, pictured to the right.

John Elden earned notoriety when according to legend his six year old son, Little John Elden, was felled by a gunshot, purportedly by a disgruntled stranger named Bob Roberts attempting to water his horse at the spring but was turned away by Mrs. Elden. A citizens posse was formed to track down and catch Roberts, and Roberts was killed shortly afterwards under unknown circumstances. Elden then abandoned the home-site and moved his family to California to start a dairy business. However, none of the legendary story regarding the murder of Little John, the murder of Roberts, or the citizen's posse any basis in historical fact in that no valid historical records were ever found,[9] although the Little John grave site today remains a historical marker next to the home-site.[10]
