The Cumbres de Monterrey ({{lang-es|Parque Nacional Cumbres de Monterrey}}, {{Audio-IPA|CumbresdeMonterrey Pronunciation.ogg|['kumbres de monte'rei]|}}; English: "Summits of Monterrey") is a national park of Mexico located in the northern portion of the Sierra Madre Oriental in the states of Nuevo León and Coahuila, near the city of Monterrey. The park protects more than {{convert|1770|sqkm|sqmi}} of rugged terrain boasting deep canyons, rivers, waterfalls, and scenic mountain peaks, including the Cerro de la Silla ("Saddle Mountain"), part of Monterrey's famous skyline.

The park was created in 1939 under president Lázaro Cárdenas to protect the native flora and fauna against the spreading urbanization of the city of Monterrey. The cool pine-oak forests with winding trails through the mountains make this park a popular escape from the nearby metropolis.

History

There are numerous indigenous paintings and stone carvings throughout the park that have proven humans have inhabited the area for thousands of years. Before the Spanish colonial period, different groups of Chichimeca inhabited the present area of Cumbres de Monterrey. Many of the different tribes in the region united for years in efforts to avoid Spanish rule. Monterrey became the first European settlement in the area when it was founded on September 20, 1596.^[2]

Cumbres de Monterrey National Park was established on November 24, 1939, by president Lázaro Cárdenas.^[1] The park was decreed to encompass {{convert|246,500|ha|acre|abbr=off}}, which at the time was the largest area to be declared protected by the Mexican government as a national park. By decree on November 17, 2000, Cumbres de Monterrey National Park was reduced to an area of {{convert|177,395.95|ha|acre|abbr=off}}.^[3]

Geography

The most accessible portion of Cumbres de Monterrey is Chipinque on the edge of Monterrey, about {{convert|19|km|mi}} from downtown. At the visitor's center, park officials provide information and maps of several hiking paths varying from easy to moderately difficult.^[4] Chipinque is an ecological reserve within the park that allow visitors easy access to much of the flora and fauna found in the park.^[5]

The park is located in the northern portion of the Sierra Madre Oriental, which was formed by rock folding of marine based sedimentary strata during the Eocene epoch in the Laramide orogeny period. The marine sedimentary rock rose over the years to an elevation of {{convert|2260|m|ft|abbr=on}} above sea level. The highest peaks in the park include:

• Pinar: {{convert|1515|m|ft|abbr=on}} above sea level
• Cerro de la Silla: {{convert|1820|m|ft|abbr=on}} above sea level
• La Ventana: {{convert|1955|m|ft|abbr=on}} above sea level
• La Antenna: {{convert|2015|m|ft|abbr=on}} above sea level
• M Este: {{convert|2020|m|ft|abbr=on}} above sea level
• Copete de las Águilas: {{convert|2260|m|ft|abbr=on}} above sea level

The main sedimentary rock that constitutes the mountains in the park was formed during the Cretaceous period. Most of the sedimentary rock features extensive karstification that happened over millions of years, creating several underground systems such as subterranean rivers, caves, and aquifers. Grutas de García (García Caves) is one of the largest cave system in Mexico and one of the most popular attractions within the park. García Caves were hidden for millions of years until being discovered in 1843. Marine fossils have been discovered inside these caves because the lining of the caves mainly consists of oceanic sedimentary rock.^[6] The porous sedimentary rock in the park allows water to filter into subterranean rivers that replenish underground aquifers, which provide one of the primary sources of water for the city of Monterrey. Pozo del Gavilán (Eagle's Hole), the only cenote known in northern Mexico is located in the southern tip of the park; it is another prime example of karstification. Pozo del Gavilán is a popular site to rappel and is subterraneously connected to Laguna de Labradores (Labradores Lake).

Cañón de la Huasteca, the most famous of the many canyons found in Cumbres de Monterrey, accounts for about {{convert|200|ha|acre}} of the park. The walls of Cañón de la Huasteca are marked with a significant number of prehistoric glyphs created thousands of years ago by the ancient inhabitants of the region.^[7] Another popular canyon is Matacanes Canyon where there are several waterfalls, of which Cascada de Chipitín (Chipitín Falls) is the most famous.

Throughout the park there are numerous waterfalls, and there may be more to be found because there is an extensive cave system with large amounts of water not drained by surface streams and rivers but rather by subterranean ones. The two most famous waterfalls are Cascada Cola de Caballo (Horsetail Falls) and Cascada de Chipitín. Easily accessible by a trail, Horsetail Falls is one of the highlights of the park with a spectacular {{convert|25|m|ft|abbr=on}} drop; the water pours over large rounded boulders in a way that resembles a horse's tail. Chipitín Falls is not easily accessible and requires a difficult hike, some rappelling, and swimming; the waterfall has an impressive {{convert|27|m|ft|abbr=on}} drop. In addition to the many surface streams and rivers there are many ponds and small lakes. The best known lake is Laguna de Labradores.^[8]

Climate

The climate throughout the park changes drastically depending on the elevation and the location of the terrain. According to the Köppen climate classification there are several climates within the park. The following climates are listed by elevation in the park.^[9]

Elevation {{convert|600|-|1,000|m|ft|abbr=on}}: North tip of the park has a (BWh) desert climate with an average annual temperature of {{convert|23|°C|°F|abbr=on}} and an annual precipitation of {{convert|21.7|cm|in|abbr=on}}. The southeast corner and central east portion of the park has a (Awh) Tropical Savanna climate with mild winters, summer-autumn monsoon, annual precipitation of {{convert|106.4|cm|in|abbr=on}}, and an average annual temperature of {{convert|21|°C|°F|abbr=on}}.

Elevation {{convert|1,000|-|2,000|m|ft|abbr=on}}: North tip and the southwest corner of the park has a (BSk) Steppe Climate with an average annual temperature {{convert|21|°C|°F|abbr=on}}. Central portion of the park has a (Cwa) Humid Subtropical climate with an average annual temperature of {{convert|21|°C|°F|abbr=on}} and an annual precipitation of {{convert|62|cm|in|abbr=on}}.

Elevation {{convert|2,000|-|3,000|m|ft|abbr=on}}: Western side of the park has a (Cwb) Oceanic climate with an average annual temperature of {{convert|14|°C|°F|abbr=on}} and an annual precipitation of {{convert|68|cm|in|abbr=on}}.^[10]

Flora and fauna

The Cumbres de Monterrey National Park is home to a great variety of ecosystems due to the geography of the park where there are many microclimates allowing a greater variety of flora and fauna to flourish. Agave, Dasylirion, and Rhus species are found in many areas of the park. The forest is made up mainly of the following tree species:

• Spruce: Picea martinezii, Picea engelmannii
• Yucca: Yucca carnerosana, Yucca filifera
• Douglas fir: Pseudotsuga lindleyana, Pseudotsuga flahualti
• Fir: Abies vejarii, Abies hickelii, Abies hidalgensis, Abies durangensis
• Oak: Quercus fusiformis, Quercus greggii, Quercus hipoxlanta, Quercus laeta, Quercus saltillensis
• Pine: Pinus ayacahuite, Pinus cembroides, Pinus greggii, Pinus hartwegii, Pinus pinceana, Pinus pseudostrobus, Pinus rudis, Pinus teocote

The pine and oak forests and steppe are home to many animals. The park has one of the most diverse ecosystems in the northern part of Mexico. There is a large variety of fish that can be found in the park, but most species are endangered. Among the fish species present in the park are Astyanax mexicanus, Campostoma anomalum, Cichlasoma cyanoguttatum, Cyprinella lutrensis, Etheostoma grahami, Gambusia affinis, Macrhybopsis aestivalis, Notropis amabilis, Notropis braytoni, Notropis stramineus, Poecilia mexicana, Puntius conchonius, and Xiphophorus couchianus. Even though there are many species of fish, the following are the only known endemic species: Cyprinella rutila, Dionda melanops and Moxostoma albidum. A significant number of Cyprinodon species still exists but many are endangered or have gone extinct.

The park hosts a large variety of bird species, including Accipiter striatus, Aquila chrysaetos, Circus cyaneus, Falco columbarius, Falco mexicanus, Falco peregrinus, Rhynchopsitta terrisi, Speotyto cunicularia, and Spizella wortheni. The park's mammals include Puma concolor, Ursus americanus, Canis latrans, and Odocoileus virginianus.
