Montalban Gorge
The Pamitinan Protected Landscape is a Philippine protected area of approximately in the Sierra Madre mountain range, just northeast of Manila. It contains and protects the Montalban Gorge formed by the Marikina River that separates Mount Pamitinan and Mount Binacayan in the municipality of Rodriguez in Rizal. Established in 1996 through Proclamation No. 901 issued by President Fidel Ramos, the park is originally a component of the Mariquina Reserve founded in 1904 to protect the watershed of the Marikina River that supplied water to the city of Manila from the Wawa Dam located just above the Montalban Gorge in the early 1900s. The park is visited for its scenic views, as well as for recreational activities as hiking, mountain climbing, spelunking and historical sightseeing. It includes the Pamitinan Cave which played a role during the Philippine Revolution and World War II, and is the setting of a popular local legend called ''Bernardo Carpio''.

Rizal
Rizal, officially the Province of Rizal ( fil, Lalawigan ng Rizal), is a Provinces of the Philippines, province in the Philippines located in the Calabarzon region in Luzon. Its capital is the city of Antipolo. It is about east of Manila. The province is named after José Rizal, one of the main national heroes of the Philippines. Rizal is bordered by Metro Manila to the west, Bulacan to the north, Quezon to the east and Laguna province, Laguna to the southeast. The province also lies on the northern shores of Laguna de Bay, the largest lake in the country. Rizal is a mountainous province perched on the western slopes of the southern portion of the Sierra Madre (Philippines), Sierra Madre mountain range. Pasig served as its capital until 2008, even it became a part of the newly created Metro Manila, National Capital Region since November 7, 1975. A provincial capitol has been in Antipolo since 2009, making it the administrative center. On June 19, 2020, President Rodrigo Duterte ...

Pamitinan Cave
Pamitinan Cave is a limestone cave in the foothills of the Sierra Madre mountain range near Wawa Dam in Rizal, the Philippines. It is located in the Pamitinan Protected Landscape, in the barangay of San Rafael, municipality of Rodriguez. The cave was formerly known as the '"Cave of Bernardo Carpio"'. Its former name was derived from Bernardo Carpio, a figure in Philippine mythology who was rebuked by the gods because of his insolence. Legend states that he was chained forever in the Montalban gorge, cursed to keep two mountains from colliding with each other. On April 12, 1895, Andres Bonifacio along with eight other katipuneros declared the Philippines independence from the Spanish empire inside of this cave. The walls still bear inscriptions of ''"Viva la Independencia Filipina"'' from the time of the Philippine Revolution. On June 21, 1996, Pamitinan cave was declared a historic site by the National Historical Commission of the Philippines. During World War II, Japanese so ...

Cave Coral
Cave popcorn, or coralloids, are small nodes of calcite, aragonite or gypsum that form on surfaces in caves, especially limestone caves. They are a common type of speleothem. Appearance The individual nodules of cave popcorn range in size from 5 to 20 mm and may be decorated by other speleothems, especially aragonite needles or frostwork. The nodules tend to grow in clusters on bedrock or the sides of other speleothems. These clusters may terminate suddenly in either an upward or downward direction, forming a stratographic layer. When they terminate in a downward direction, they may appear as flat bottomed formations known as trays. Individual nodes of popcorn can assume a variety of shapes from round to flattened ear or button like shapes. The color of cave popcorn is usually white, but various other colors are possible depending on the composition. Formation Cave popcorn can form by precipitation. Water seeping through limestone walls or splashing onto them leaves depo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rimstone
Rimstone, also called gours, is a type of speleothem (cave formation) in the form of a stone dam. Rimstone is made up of calcite and other minerals that build up in cave pools. The formation created, which looks like stairs, often extends into flowstone above or below the original rimstone. Often, rimstone is covered with small, micro-gours on horizontal surfaces. Rimstone basins may form terraces that extend over hundreds of feet, with single basins known up to 200 feet long from Tham Xe Biang Fai in Laos. Formation Rimstone dams form where there is some gradient, and hence flow, over the edge of a pool. Crystallization begins to occur at the air/water/rock interface. The turbulence caused by flow over the edge of the building dam may contribute to the outgassing or loss of carbon dioxide from water, and result in precipitation of mineral on this edge. When dams form under running water, they tend to be higher when the passage is steeper. Shallow-gradient dams tend to be lower a ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Gap
A water gap is a gap that flowing water has carved through a mountain range or mountain ridge and that still carries water today. Such gaps that no longer carry water currents are called wind gaps. Water gaps and wind gaps often offer a practical route for road and rail transport to cross the mountain barrier. Geology A water gap is usually an indication of a river that is older than the current topography. The likely occurrence is that a river established its course when the landform was at a low elevation, or by a rift in a portion of the crust of the earth having a very low stream gradient and a thick layer of unconsolidated sediment. In a hypothetical example, a river would have established its channel without regard for the deeper layers of rock. A later period of uplift would cause increased erosion along the riverbed, exposing the underlying rock layers. As the uplift continued, the river, being large enough, would continue to erode the rising land, cutting thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barangay
A barangay (; abbreviated as Brgy. or Bgy.), historically referred to as barrio (abbreviated as Bo.), is the smallest administrative division in the Philippines and is the native Filipino term for a village, district, or ward. In metropolitan areas, the term often refers to an inner city neighborhood, a suburb, or a suburban neighborhood or even a borough. The word ''barangay'' originated from ''balangay'', a type of boat used by a group of Austronesian peoples when they migrated to the Philippines. Municipalities and cities in the Philippines are politically subdivided into barangays, with the exception of the municipalities of Adams in Ilocos Norte and Kalayaan in Palawan, with each containing a single barangay. Barangays are sometimes informally subdivided into smaller areas called ''purok'' ( en, "wikt:zone, zone"), or barangay zones consisting of a cluster of houses for organizational purposes, and ''sitios'', which are territorial enclaves—usually rural—far from t ...

Sitio
A ''sitio'' (Spanish for "site") in the Philippines is a territorial enclave that forms part of a barangay. Typically rural, a ''sitio'''s location is usually far from the center of the barangay itself and could be its own barangay if its population were high enough. ''Sitios'' are similar to '' puroks'', but the latter are more urban and closer to the center of the barangay, especially the barangay hall. The term is derived from the Spanish word ''sitio'' meaning "place". During the Spanish colonial period the colonial government employed the '' reducción'' policy, allowing the remapping of various settlements. Several far-flung hamlets were identified, named, and organized into "sitios" so that municipalities and cities could more easily be governed through the barangay system, then known as the ''barrio'' system. A ''sitio'' does not have an independent administration; it is established purely for organizational purposes only. See also * Purok * Poblacion * Barangay ...
