Classes include those in computer and industrial systems as well as certain types of high school level classes. The classes are giving at the Casa de Cultura in rooms which have been adapted for the purpose.

The main highway in the municipality is Federal Highway 69. A state highway connecting Jalpan with San Luis Potosí was built through here in 2000. In 2004, a highway to Guanajuato was added. These are supplemented by a number of rural roads connecting the various communities. Many of these roads have public bus service, including service to neighboring states.

Aside from the municipal seat there are a number of other important communities. Purísima de Arista is the second largest community in the municipality, which also has all utilities along with schools, health center and sporting facilities. Its economy is based on agriculture growing corn, beans, chili peppers, tomatoes, chickpeas and squash. It is located 36 km from the municipal seat. The town has a parish church was built in 1909. The Virgin of the Immaculate Conception is honored in Purísima de Arista on 8 December. Río de Carrizal is a small community located at an altitude of 600 masl, so it has a warm, subtropical climate.

San Juan Buenaventura is located 48 km from the municipal seat and at an altitude of 1600 masl. The town is divided into the communities of El Bosque, San José de las Flores, El Quirino, La Mohonera and Laguna de la Cruz. Most of its economy is based on livestock.

The Concá delegation has the largest number of communities and is located 15 km from the municipal seat in the most agriculturally productive area of the municipality. Its agriculture along with tourism from the mission church has made it one of the most important communities in the region. The town of Concá is noted for its commemoration of Day of the Dead

Demographics

The municipality is part of the traditional territory of the Pame

 people, which extends over northern Querétaro and southern San Luis Potosí. In Querétaro, they are found in Jalpan de Serra and Arroyo Seco, especially San José de las Flores, El Rincón and El Rincón. Among themselves, they organize into groups called “desisorias” which are tightly knit communities which interact with other similar units for public services such as education and health. As of 2005, the census counted only sixty six people who spoke an indigenous language, Pame and Otomi
Otomi language
Otomi is an Oto-Manguean language and one of the indigenous languages of Mexico, spoken by approximately 240,000 indigenous Otomi people in the central altiplano region of Mexico. The language is spoken in many different dialects, some of which are not mutually intelligible, therefore it is in...

. However, only a third of all Pames speak the language with over half being monolingual in Spanish. Disease in the colonial period and displacement, sometimes forced expulsion of Pame peoples nearly extinguished the ethnicity in Arroyo Seco, but since the early 20th century, there has been some migration of Pame back into the area. Pames generally live in homes made of palm, adobe

 and wood which can measure from 300 to 1000m2, rectangular with pitched roofs. The inside is generally a single room which includes a kitchen and places to sleep. Most Pame raise small livestock such as pigs and domestic fowl for sale or self consumption. Land is held by communities in common with certain authorities to regulate its use in places such as San José de las Flores, and El Rincón. Common handcrafts include items made from palm fronds such as mats and pottery, including comal

Comal can refer to:*COMAL, a computer programming language*Comal , frequently used to cook tortillasComal is the name of several places:*Comal County, Texas*Comal River, Texas*Comal Springs...

s and other cooking utensils. They also fashion wood into furniture and masks for sale or their own use. A number of these communities have received official recognition from the municipality as “Pueblos Indígenas” (Indigenous Villages). This allows the communities to petition for funds from the Comisión Nacional para el Desarrollo de los Pueblos Indígenas (CDI). The communities are Tierras Prietas, El Sabinito, Crucero del Sabinito, Las Trancas, La Cantera, El Riachuelo, San José de las Flores and San Juan Buenaventura.

The overwhelming majority of the population is Catholic, with four parish churches and the Concá mission church. The last church is directly administered by the Diocese of Querétaro

. However, overall, the tendency of the population is negative. The population declined from 12,667 in 2000 to 12,493 in 2005. Arroyo Seco is the least populated in the Sierra Gorda region. Most of its communities have a population of between one and ninety nine inhabitants. The main for the decline is the emigration of much of its population due to poverty.

Most of the territory is mountainous, with gradients of over 25%. Altitudes in the territory range from 560 to 1340 masl with an average of 980masl. The mountain formations are subdivided into two parts. The first is a corridor along the border with Jalpan which is over forty km long and five km wide. This area has some very low valleys of only 700 masl. The second area is more rugged with canyons of up to 600 meters deep and peaks which reach over 2000 masl. There are a number of flat areas and valleys which are mostly along the Ayutla and Concá rivers. The principle elevations are Santo Domingo, Cantera, Cofradía, Soledad and Pitorreal.

The terrain is composed of sedimentary rock, mostly layers of limestone

, which present on the surface with medium or fine grain and sometimes as clay. It, like most of the Sierra Gorda, is on former sea bed from 150 million years ago. Recently, Arroyo Seco and other municipalities of the Sierra Gorda have reported numerous small earthquakes. According to seismologists, these are caused by the movement of water through sedimentary rock. Erosion causes gaps and then the gaps settle onto themselves, causing the small quakes. One thing scientists are checking for is to see if any areas stand over underground cavities which may give way.

The area’s location over the Huasteca Karst and the erosion of limestone has given rise to numerous pit caves. The largest of these in the Sierra Gorda is located in Arroyo Seco, called the Sótano de Barro, located in the Santa María de los Cocos community. The Sótano del Barro is one of the largest cavities of the world by volume, measuring 15 million cubic metres, surpassed only the Sima Mayor de Sarisariñama in Venezuela

. In comparison the Sótano de Las Golondrinas has a volume of only five million meters cubed. Its widest diameter measures 420 meters and its average width is 200 meters. It has a total depth of 455 meters with a direct drop of 410 meters. Its perimeter is surrounded by dense vegetation, which is a sanctuary for green macaws

 are mostly vertical and partially covered by vegetation. At the bottom of the cave there is a small forest on a floor which was sea bed 100 million years ago, which measures 220 meters long and 100 meters wide. Despite its depth, the bottom of the pit cave receives an abundance of sunlight allowing for the growth of trees and other vegetation, making it an isolated mini forest. The bottom also has a number of small caves, with the largest fifty meters long. This pit cave has been classified as the deepest in the world although this has recently been challenged by those who wish to include those pit caves which are not continuous such as the Stary Swistak in Austria

, which has a total depth of 480 meters.

Principle river systems include the Santa María, the Ayutla and the Jalpan with their tributaries such as the Concá River in the south of the municipality. The Santa María enters the municipality from San Luis Potosí and flows along a 400 meter deep canyon until it merges with the Ayutla River. This river flows northeast, forming another canyon then merges with the Jalpan River. There are about 100 accessible sources of water in the municipality with most located in the communities of Salitrillo, Concá and Ayutla. The municipality is home to the junction of two of the major rivers of the Sierra Gorda, the Santa María and the Ayutla River at a location called Las Adjuntas. The Santa María River here flows warm to hot in the summer and the Ayutla River remains cold. Although the two rivers have different water colors and temperatures, both are regulated by the surrounding environment. The Santa María River has a number of beaches which are open to camping. There is also sports fishing of native catfish. The northern border of the municipality is partially formed by the Verde River. The Concá Waterfall is located just south of the town of the same name. This waterfall is fed by a fresh water spring and falls into the Santa María River. Despite the name (which means dry stream or dry arroyo
Arroyo (creek)
An arroyo , a Spanish word translated as brook, and also called a wash is usually a dry creek or stream bed—gulch that temporarily or seasonally fills and flows after sufficient rain. Wadi is a similar term in Africa. In Spain, a rambla has a similar meaning to arroyo.-Types and processes:Arroyos...

), most of the arroyos in the area have water in them most of the year. The municipality has ten easily accessible sources of surface water. However, the over extraction of water has led to dropping water tables and many of the area’s fresh water springs are flowing at slower rates or have dried up.

The municipality divides into two climate regions. The north is semi arid with an average temperature of 22C and an annual rainfall of between five and 10.5mm per falling mostly in the summer. The other is semi hot with average temperatures varying from 18 to 22C with rains in the summer. In the winter, the area is vulnerable to cold spells, brought in by cold fronts that arrive from the north and west. The cold spells do not usually reach freezing as the municipality does not have the high peaks that neighbors such as Pinal de Amoles

 does, but snow mixed with rain fell in 2006 and in 2010, freezing temperatures did reach communities such as La Florida and San Juan Buenaventura. Very cold temperatures can prompt emergency services such as the provision of blankets by the municipality’s civil protection service or evacuation to shelters. Communities which are most vulnerable to severe cold include La Sanguijuela, La Escondida de Guadalupe, La Cantera, Río del Carrizal and El Durazno. The area has had problems with droughts over the past decade, especially in 2009, which have been draining reserves and aquifers. The lack of water has caused the deaths of livestock and forced more people to emigrate from the municipality. Many communities now must rely on water trucked in from outside.

The Concá mission is the smallest of the five, but between 1754 and 1758 by José Antonio de Murguía and Joaquin Fernández Osorio. It is dedicated to the Archangel Michael, with the theme of the facade being “The Victory of the Faith.” It is considered to have the most indigenous elements, with many of its elements showing the more brusque work characteristic of indigenous decoration. More obvious is an image of the Holy Trinity at the crest, which is accompanied by a rabbit and a two-headed eagle, which are Pame symbols. Also prominent are the coat of arms of the Franciscan order, grapevines, two headed eagles, with the Virgin of Guadalupe and Our Lady of the Pillar, the patronesses of Mexico and Spain respectively.

History

The town was originally known as the Presidio de Arroyo Seco, a military outpost. In 1833, missionary Francisco Cano Santander gave it the ecclesiastical name of Villa de Guadalupe which was the town’s formal name until 1840, which it was changed to the current one. Its coat of arms has three parts. The first represents the Cross of the Holy Trinity with hands representing the indigenous peoples and the evangelizers. The second is the rabbit which appears on the facade of the mission church of Concá. This rabbit is the only one to appear on the five mission churches. The third is an arroyo from which the name comes.

Arroyo Seco is part of the heart of the Sierra Gorda. This region has been occupied for about 6000 years. In the Pre Classic and Classic periods

, the Sierra Gorda had a number of small cities as the climate at that time was wetter than it is now. Most of the larger cities were south of the current municipalities due to mining activities and major trade routes, but there were cities and trade routes through here as well, connecting the area mostly with Huasteca

In the late pre Hispanic period, the Sierra Gorda had incursions from both the P’urhépecha and Aztecs from as early as 1400, attracted by the area’s mineral deposits, but neither had true dominance as the Chichimecas fiercely opposed them.

The town gained municipal status in 1933. At first the new municipality was governed by a committee headed by Antonio Rubio Chávez but the first municipal president, C. Angel Torres Montes, was elected in 1935.

In 1994, the municipality decided to build a garbage dump near the archeological zone of San Rafael without informing the Instituto Nacional de Antropología e Historia (INAH). Since 2006, it has been known that the dump sits on the southern part of the site proper and that the digging of the dump site is estimated to have destroyed between eight and ten pyramids. More vestiges of the site lie 300 meters below the dump. The municipality promised for years to move the facility and from 2006, state and federal authorities have promised to replaced it with a new one farther away. However, as of 2009, the dump is still operating taking on as much as forty tons of trash per week, as the new facility was not yet finished. In 2007, a smaller, above ground dump appeared in the same area, within sight of visible ruins. During this time, acids and other substances produced by the pit have probably caused damage to the limestone of the site, eating away at structures made of the substance. The site belongs to the Río Verde Culture and its estimated to extend over 10km2. Its importance has been compared to that of Tamtoc in San Luis Potosí

In 1998, forests in the municipality were among those in five states destroyed by wildfires. In total, 180 hectares were burned. The fires were due to freezing conditions in the prior winter which dried out grasslands.

In the latter 2000s, the municipality has been struggling with water shortages due to drought conditions. The lack of water has caused the deaths of livestock and forced more people to emigrate from the municipality. Many communities now must rely on water trucked in from outside. As of 2007, sixteen out of forty six communities in the municipality have significant problems with water shortages. The government states that this is because a number of wells are drying up and there is insufficient distribution. In the second largest community of Purísima de Arista, about half of the residents experience water shortages. In 2009, the municipality had number of cases of cattle dying due to bites from “vampire” bats which were transmitting a type of paralytic rabies

. The bats were coming from caves located in neighboring Guanajuato.

From the latter 2000s to the present, Arroyo Seco and the rest of the Sierra Gorda in Querétaro have been experiencing numerous small earthquakes, with most registering from 2.5 to 3.5 on the Richter scale, generally imperceptible to humans. Seismologists say that while the number has been unusual, such activity is not and is due to the settling of the sedimentary rock which is below most of the Sierra Gorda region. However, Arroyo Seco and other municipalities have seismographs installed to monitor the situation.

The municipality’s recent history also includes the mass migration out by many of its working aged people due to lack of economic opportunity. Most have gone to the United States with as much as forty percent of the municipality’s population living in the country alone. The money that these workers send back home have significantly changed the local economy, as it is larger than the locally generated economy and larger than annual municipal budget. The migration has caused municipality schools, especially primary schools to lose students as they leave for the United States with their parents.

In 2006, the municipality elected its first non-PRI

Construction of a military base was begun in early 2011 at a three hectare site. The base is one of three being built to work against drug trafficking and other crimes along the Querétaro/San Luis Potosí border. This base is part of the 17th Military Zone to patrol the Querétaro-San Luis Potosí border. The military is there to countering drug trafficking in the area as the region does not have the resources for local police forces.

Economy and tourism

The municipality is one of the most economically marginalized in the state, with the Secretaría de Desarrollo Social (SEDESOL) cataloging it as one of the 200 most socioeconomically marginalized in the country. This is the main reason why Arroyo Seco and other municipalities in the Sierra Gorda of Querétaro have high rates of emigration. It is not known exactly how many have left or how many come back at the end of the year to visit family, but Arroyo Seco estimates that about forty percent of its population is living somewhere in the United States. The amount sent back in remittances is also not known, but it has been estimated at between 50,000 to 100,000 USD per day or about 18 million USD per year to the Sierra Gorda alone, based on money exchanges made the in the main city of Jalpan de Serra. This amount supersedes the annual municipal budget of Arroyo Seco and other area municipalities and generally superseded money generated by municipal economies. In Arroyo Seco, one in four homes is supported by dollars send home by family in the United States. These migrants not only provide remittances directly to their families, they have also formed clubs with the purpose of promoting infrastructure projects in their home communities. The Club de Migrantes de la Sierra Gorda is an association of twenty seven of these clubs from various municipalities, with three from Arroyo Seco. Most of the projects are related paving, water distribution and sewerage/drainage. These dollars are often matched through a program sponsored by the Mexican federal government. Many businesses in the municipality and the rest of the Sierra Gorda take the dollar as currency, especially at the end of the year when many come to the area to visit family. Arroyo Seco has one of the highest rates of emigration in Querétaro. Arroyo Seco is one of the sponsors of the Día del Paisano to honor returning migrant workers in Jalpan de Serra. This events includes parades and raffles.

Because of this emigration, only 23.36% of the total population is economically active, mostly employed in traditional economic activities, such as agriculture, livestock, forestry and general commerce. About twenty percent of the total population works at home for no pay. Women make up only 22% of the paid workforce. Most of those who are not economically active are students and housewives.

Most of the territory is used for pasture and forestry, with total about ninety percent. The rest is used for agriculture, most of which is done only during the rainy season. Just over 43% of the economically active are working agriculture, livestock, forestry and fishing. Thirty of the municipality’s communities engage in agriculture to some degree with most of the production for self consumption. The soil is fertile although it is sometimes hard with some drainage problems. These problems are greatest where the topsoil is less than ten centimeters. One problem with agriculture here is that the soil erodes easily. Fruit trees include mango

The forests of the municipality make up about sixteen percent of the state’s forest resources and cover 54% of the municipality. Over eighty percent of the forest is made up solely of broad-leafed trees with most of the rest a mix of broad-leafed and conifers. Logging is limited because of the tropical hardwoods here and conservation efforts related to the Sierra Gorda Biosphere Reserve, but it still makes up over 15% of the state’s total. About 19% of the forested lands are used for grazing. Fish farming is a growing segment of the economy, especially in communities near rivers such as Río del Carrizal, Concá, Vegas Cuatas and Ayutla.
About 25% are working in mining, construction, utilities and manufacturing.

Commerce, transportation and services employ about eighteen percent. There are about 140 people dedicated to commerce, most of which is small grocery stores. Supermarkets and other similar stores are located in neighboring San Luis Potosí in Río Verde and San Ciro

During the colonial period, there were several haciendas in the municipality. One of these was San Nicolás de Concá, which still has abundant vegetation, a large fresh water spring and hiking trails. The main house has been converted into a hotel, conserving part of the original structure made of adobe, with rustic stairs, wooden roof beams and gardens. The San Nicolas Conca hotel is owned by an American by the name of Sharpton. The hacienda was originally dedicated to sugar cane and dates from the 18th century.

Archeology

The San Rafael site was first documented in 1939 by the Instituto Panamericano de Geografía e Historia. Some work was done on the site by archeologists such as Dominique Michelet for about a decade. This work determined that the site was occupied from 200 to 900 CE as a Mesoamerican city with temples, plazas, patios and residences located around four Mesoamerican ball courts. The city was an regional seat of government with strong Huasteca influence. It had a total of 250 buildings even larger than the better known sites of Las Ranas and Toluquilla .

Eight to ten structures are considered destroyed and more may have suffered irreversible damage by acids eating way the limestone blocks. As of 2006, the limits of the sites have still not been defined. The vestiges of the site lie about three hundred meters below the dump. The site belongs to the Río Verde Culture and its estimated to extend over 10km2. Its importance has been compared to that of Tamtoc in San Luis Potosí.
