Location and surroundings
Limestone Mountain lies in the Pedregosa Mountains, within the Chiricahua Mountains, the Southeast Arizona Ranges, the Southwest Basins and Ranges, the Intermountain West and the North American Cordillera. It is in Cochise County, Arizona, in the United States. Among the named peaks of the Pedregosa Mountains, it is the highest, and the range itself is the high point of that small mountain group.
The mountain rises in a dry, open part of southeastern Arizona where rocky slopes, scrub and scattered woodland are typical at this elevation. The terrain around it is shaped by ridges and intervening basins rather than by continuous high alpine ground, so approaches are likely to involve exposed hillsides and long views across the surrounding country.
Neighbouring peaks
The nearest named peaks and passes give a clear sense of Limestone Mountain’s position in the range:
- Sunset Peak — 2,142 m, 6.4 km north
- Bruno Peak — 2,095 m, 7.6 km northwest
- Swede Peak — 2,281 m, 7.9 km northeast
- Packsaddle Mountain — 1,921 m, 9.5 km southwest
- Dobson Peak — 2,383 m, 11.9 km northeast
- Erickson Peak — 2,433 m, 12.1 km northeast
- Red Hill — 1,533 m, 14.1 km southeast
- May Day Peak — 1,927 m, 14.8 km northeast
Of these, Swede Peak is the nearest higher peak. Limestone Mountain is lower than several nearby summits to the northeast, but it remains the highest point in its own range.
The view from the summit
From the summit area, the highest peaks within 25 km are part of the same mountain country to the north and northeast. The main high points listed for the wider view are Chiricahua Peak at 2,979 m, 20.6 km north; Flys Peak at 2,948 m, 23.7 km north; Snowshed Peak at 2,936 m, 20.5 km north; Raspberry Peak at 2,871 m, 18.0 km north; Finnicum Peak at 2,746 m, 19.3 km northeast; and Johnson Peak at 2,709 m, 18.3 km north.
These peaks show that Limestone Mountain sits on the southern side of a higher cluster of summits. The outlook is likely to be broad, with higher ridges visible in the distance and lower country opening away to the south and west.
The range
Limestone Mountain is the highest mountain in the Pedregosa Mountains, which are the high point of that range group. The Pedregosa Mountains contain five named peaks, and Limestone Mountain ranks first among them by elevation. The range belongs to the larger chain of the Chiricahua Mountains in southeastern Arizona.
The highest peak of the Pedregosa Mountains is Limestone Mountain itself, so there is no higher summit within that small range. Its position at the top of the local ranking makes it the reference point for the group, even though much higher peaks lie farther north in the broader mountain system.
Climate and weather
Climate estimates from NASA POWER for 2001–2020 suggest that the summit is above freezing in every month. The warmest month is June, at about 22 °C, and the coldest is January, at about 4 °C. The surrounding area receives about 350 mm of precipitation a year, with the wettest month in July at about 95 mm and the driest in April at about 5 mm.
In this part of Arizona, the main weather hazards are heat, strong sun, dry air and sudden summer storms that can bring brief heavy rain and lightning. Even at summit height, conditions can change quickly when monsoon moisture moves in, while winter and early spring can still bring cold mornings and wind.
Best time to visit
Because the summit is estimated to stay above freezing all year, the main timing question is not snow cover alone but heat, storms and water. The drier months are generally the spring months before the summer rains, while July is the wettest month and often brings afternoon storm risk. For many visitors, late spring and early summer offer the most manageable balance of temperature and weather.
In midsummer, the mountain can be hot at lower elevations and exposed to thunderstorms later in the day. In winter, the air is cooler but still usually mild enough for daytime travel, so early starts and flexible plans matter more than a strict seasonal closure.
Nature and wildlife
The mountain lies in a dry southeastern Arizona landscape where lower slopes usually carry desert scrub and grassland, with more tree cover on cooler or moister aspects and at higher elevations. Rocky ground, open ridges and seasonal washes are typical in this part of the state. Wildlife in the region commonly includes birds of prey, reptiles and mammals adapted to arid mountain country.
At this elevation, vegetation is usually a mix of drought-tolerant shrubs and scattered woodland rather than continuous forest. After summer rain, the hills can green up quickly, but water remains limited and wildlife activity often follows the cooler parts of the day.
Guides and organised ascents
For a mountain like Limestone Mountain, a certified guide is usually most useful if you want local route-finding help, a safer plan in hot or storm-prone weather, or support for a longer backcountry outing. In the United States, the national guide association is the American Mountain Guides Association, an IFMGA/UIAGM member, and the national alpine club is the American Alpine Club. Examples of established guiding companies in the country include RMI Expeditions and Exum Mountain Guides.
Guided ascents in the United States typically depend on the length of the trip, group size, equipment needs and whether extra days or overnight logistics are involved. For this mountain, there is no special permit rule, so normal land-access planning and local regulations would apply. Visitors usually check with the relevant land manager or local tourism contacts before setting out.
Safety and preparation
Limestone Mountain is a 2,183 m peak in dry mountain terrain, so preparation should focus on sun protection, enough water, navigation and weather awareness. The combination of open slopes, heat and summer storms means that a short outing can still become demanding. Good footwear, a map or offline navigation and an early start are sensible basics.
For mountain rescue in the United States, the emergency number is 911. Dispatchers alert the local search and rescue team, usually run by the county sheriff or a national park authority. In remote country, mobile coverage may be unreliable, so it is wise to tell someone your plan before leaving.
Interesting facts
Limestone Mountain is the highest of the five named peaks in the Pedregosa Mountains. Its nearest higher peak is Swede Peak, 7.9 km to the northeast. The highest point of the range is Limestone Mountain itself, which makes it the local reference summit even though much higher peaks lie farther north in the broader mountain system.
The mountain belongs to the long chain of the North American Cordillera, but its immediate setting is a compact range in southeastern Arizona. That contrast between a small local high point and a much higher regional skyline is one of its defining features.
FAQ
How high is Limestone Mountain? It rises to 2,183 m.
Where is Limestone Mountain? It is in Cochise County, Arizona, in the United States, within the Pedregosa Mountains of the Chiricahua Mountains.
