MAP: SF-19-2
NAME: IQUIQUE
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Iquique

• Salar Grande
• Salar Bellavista
• Salar de Pintados

• No mountains selected

• This map has hardly any likely sites due to the large lowland where the Salar's are located. It also has most of the mining activity in the First region, along the coast there are 5 major mines that are mining the Salar's located there and towards the mountains there are three mines, Cerro Colorado,Sagasca and Quebrada Blanca all mining copper.

MAP: SF-19-3
NAME: COLLACAGUA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Mining Activity
• Dona Ines de Collahuasi

• Salar de Huasco
• Salar de Coposa

• No mountains selected

• Lots of mining activity in the southern portion of this map (Dona Ines de Collahuasi on the southern edge) excluded searchs for mountains in that area, not that there were any good sites anyway, there were no apparent mountains by themselves or above the local terrain, most had mountains at the same level or higher to the North and West, producing possible turbulence.

MAP: SF-19-6
NAME: QUILLAGUA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Mining in the Salar Grande
• Off the West side of the map is the El Abra mine
• Off the North side of the map is the Collahuasi mine

• Salar Grande
• Salar de Llamara
• And absolutely nothing else...

• No mountains selected

• There is very little of interest on this map, there is no coastal range of mountains above even 2000m, most of the map is dominated by some impresive salar's, the only possible locations for a site are on the Western cordillera, where there is extensive mining activity in large quantities in both the North and South, aside from the mining all the mountains are in a line running North-South and are at the same height of about 3000m -3500m

MAP: SF-19-7
NAME: OLLAGUE
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Ollague
• El Abra mine
• Collahuasi mine
• Minor Mines and not so minor mines all over the place

• Salar de San Martin
• Salar de Ascotan
• Salar de Ollague
• Ollague
• Volcan San Pedro(Fumarolic activity) y San Pablo 6000m

• Cerro Yacas
• Cerro Tres Monos

• This map has heavy mining activity going on all over the place, with more going up all the time, the El Abra mine as of 1997 is pulling out 225000 tones of copper and has had a billion dollars invested in it, there is the Collahuasi mine just off the NW portion of this map, that is probably the largest new mining project to be developed this decade $US1.8 billion . There are few mountains that aren't affected by wind coming from mountains in front of them.

MAP: SF-19-10
NAME: TOCOPILLA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Pedro de Valdivia mine
• Maria Elena mine
• Tocopilla
• Chuquicamata mine
• Calama

• A bout 80% of this map is flatland below 2000m

SELECTED MOUNTAINS

• No mountains selected

No mountains were selected due to the closeness of large mines with direct line of sight to the one or two possible sites , it was difficult to select sites due to the fact that at least 80% of the map lies under 2000m, with no interesting coastal peaks. The sites have light from both Tocopilla located on the coast, Chuquicamata and Calama from the cordillera, and to really make things difficult there are two large mines in the middle of the map. A possible site would be Co Viriera 2000m on the SW portion of the map.

MAP: SF-19-11-12
NAME: CALAMA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Chuquicamata mine
• Calama
• El Abra mine
• San Pedro de Atacama
• Minor Mines

• Salar de Atacama
• Salar de Turi

• Cerro Chaxas
• Cerro Silaguala
• Co Guacho Pirca
• Falda de Tocopuri
• Co Jorquenal
• Cerro Chajnantor

• With the exception of the last Mountain,the map of the Calama area does not have very good sites for observatories within the 2500m - 5500m range, due to the fact that most likely spots are too close to the Calama/Chuquicamata light pollution, or are surrounded by mountains of equal size that will disrupt the local wind patterns around the selected sites. Most of the sites that are far away from cities and mining areas , such as to the East of Chajnantor, are on plains. The sites around the Chajnantor area have some good choices, however there are also lots of mountains that are small peaks on a plain( ie: the plain is at 4500m and the mountains are 4600m high)
• D.E.M.  of the Chajnantor Area

MAP: SF-19-14
NAME: ANTOFAGASTA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Antofagasta
• Escondida mine
• San Cristobal mine
• Minor Mines

• Salar Navidad
• Salar Pampa Blanca

• Co La Punta

• Only one mountain was selected and even it was very marginal, it was difficult to select sites due to the fact that at least 80% of the map lies under 2000m, any high mountains near the coast are to close to the city of Antofagasta, and any mountains on the edge of the East side of the map that are suitable are right next to the largest gold and silver mine in the 2nd Region, the San Cristobal mine. To the south is the Escondida mine.

MAP: SF-19-15-16
NAME: TOCONAO
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• San Pedro de Atacama
• Lithium mines in the Salar de Atacama

• Salar de Atacama
• Salar de Aguas Calientes
• Minor Salar's

• Co Chascon
• Co del Quimal
• Co Toloncha
• Co Losloyo
• Co Gigante

• An interesting area, there are less mines and towns in this map, the mountains are a bit more seperated from each other, there are lots of good mountains that unfortunately are surrounded by lava. There are lithium and potassium mines that are located in the Salar de Atacama, but it seems according to the IDA's dark skies of chile light map that there is only one big mine, that pulls out 300000 ton of potassium chloride a year, owned by Minsal.

MAP: SG-19-2
NAME: AGUAS BLANCAS
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Possible Escondida mine
• Minor Mines

• Cordillera Domeyko

• Co Armazones
• Unknown ( Sierra Penafiel)

• Along the coastal range there seems to be only one other place that looks good as a site other than Paranal and that is Co Armazones. The middle of this map is characterized by a low central region with few places to put a telescope , especially in the North due to the closeness of the Escondida mine, one of the worlds largest copper mines. Down on the South East corner of the map is the Domeyko range, which seems to have lots of peaks strung out in a very straight line , but look like they would be effected by a northerly wind making mountain waves and eddies, Co Alto de Varas at 4300m seems like a good site but has direct view of Escondida close by and has a 4000m mountain only 5km to the North. Co Armazonas has a telescope on it from the Universidad Catolica del Norte.

MAP: SG-19-3-4
NAME: SIERRA ALMEIDA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Possible light problem from Escondida Mine
• Minor Mines

• Salar de Punta Negra
• Major volanic Area
• Volcan Llullaillaco(6739m)

• Co Quanquero
• Co Aguas calientes
• Co Pajonales

• There are lots of inactive volcanos in this area with old lava fields. There are also a large amount of big mountains that are on the argentine border, these mountains are mostly grouped together, which may produce wind problems, there is also a major problem with a lot of potential sites due to the Escondida mine, which is emitting huge quantities of light.

MAP: SG-19-6
NAME: TALTAL
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Taltal
• Altamira mine
• Minor Mines

• Cordillera Domeyko

• Co El Chaco
• Co Bolson, Co Encanche, Co Infieles

• A large low area is on this map, with what seems to be two large mining operations in the middle: The Altamira mine in the South and an as yet unknown mine to the North, it seems to be putting out a lot of light. The mountains along the coast are low and the ones in the Ccrdillera de Domeyko seem to be too close together or too close to a mining area.

MAP: SG-19-7
NAME: SALAR DE LA ISLA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Minor Mines

• Salar de la Isla

• Co de Azufre
• Co de la Pena
• Co Cono de la isla

• Large lava fields, with very tall mountains, the area seems to have some promising sites, that are however quite steep. The mining activity in the area does not seem to be very large, according to the IDA dark skies night map of Chile and other mining news.

MAP: SG-19-10
NAME: SALVADOR
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Salvador Mine
• Pedro de Valdivia
• El Salado
• Chanaral
• Porterillos
• La Coipa mine
• Minor Mines

• Salar de Pedernales
• Salar de Maricunga
• A big plain in the middle of the map (1300m -2000m)

• No mountains selected

No mountains were selected due to the closeness of large mines with direct line of sight to the one or two possible sites , it was difficult to select sites due to the fact that at least 60% of the map lies under 2000m, with no interesting coastal peaks.

MAP: SG-19-11
NAME: LAGUNA VERDE
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• La Coipa mine
• Minor Mines

• Salar Grande
• Laguna Verde
• Cordillera Claudio Gay
• Paso San Francisco
• Salar de Piedra Parada

• Pico Wheelwright
• Co Ermitano

Lots of tall mountains clumped together, which might produce wind problems since they are all together and at the same elevation, few choices for a site on this map, a couple of mountains 6000m tall, maybe good for IR but turbulent and high speed wind from other mountains still seems to pose the greatest problem.

MAP: SG-19-13
NAME: CALDERA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Caldera
• Copiapo
• Mining Activity around Copiapo

• 100% of this map is flatland below 1300m

SELECTED MOUNTAINS

• No mountains selected

No mountains were selected due to the very low terrain.

MAP: SG-19-14
NAME: COPIAPO
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Copiapo
• Mines surrounding Copiapo
• La Coipa mine to the North

• Salar de Maricunga
• Laguna del Negro Francisco

• Co Tronquitos
• Unknown(1km E of Quebrada Toledo)

• This map area is characterized by having most of the mountain sites with a direct line of sight to the city of Copiapo, which along with it's own light has also got a lot of mines within about a 20km radius that are also emitting their own light, this along with the fact that a lot of the mountains are mostly at the same level, makes site selection difficult. One potencially good mountain was Co de Azufre at about 6000m but according to the IDA dark skies night image of chile there is something big emitting light just to the East, that seems to be a big mine. Another high mountain 5800m that might be a possibility is Nevado de Jatabeche, these two mountains have the advantage of being taller by about a 1000-1500m above the surrounding terrain, but seem to have light pollution problems.

MAP: SH-19-1
NAME: VALLENAR
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• Vallenar
• Huasco
• Mining activity SE,E,NE of Huasco
• Domeyko mine
• Minor Mines

• None of major importance

• Co Parraguez

• Very few sites available due to the low terrain, the few good looking sites already have La silla and Las campanas on them, it might be possible to put a telescope on these mountains, space availability would have to be investigated, the Domeyko mine is a major source of light in this region and is probably already affecting the Las campanas Observatory and to a lesser extent the La Silla Observatory .

MAP: SH-19-2
NAME: EL TRANSITO
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

MAP: SH-19-9
NAME: LA SERENA
SCALE: 1:250000

MAJOR SOURCES OF LIGHT

• La Serena
• Coquimbo
• Andacollo and mines
• Vicuna

• None of major importance

• Cerro Tololo
• Cerro Pachon
• Cerro Funlimaqui
• Cerro Junquillo

• This map has several interesting sites, especially Tololo and Pachon which have had extensive use and testing over many years, it seems that the sites that have previously been selected for observatories are on ridges facing the NW, there are however problems with light pollution from La Serena, Andacollo and its mines and the valley town of Vicuna.
