La Palma in the context of "Cauldron"

The Canary Islands (/kəˈnɛəri/ ; Spanish: Canarias [kaˈnaɾjas] ) or Canaries are an archipelago in the Atlantic Ocean and the southernmost autonomous community of Spain, located about 100 kilometres (62 miles) off the northwest coast of Africa. The archipelago has a population of approximately 2.27 million inhabitants, making it the most populous overseas special territory of the European Union.

The seven main islands are from largest to smallest in area, Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The only other populated island is La Graciosa, which administratively is dependent on Lanzarote. The archipelago includes many smaller islands and islets, including Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It includes a number of rocks, including Garachico and Anaga. The island chain used to be referred to as "the Fortunate Isles". The Canary Islands are the southernmost region of Spain, and the largest and most populous archipelago of Macaronesia. It is also the largest and most populated archipelago in Spain. Because of their location, the Canary Islands have historically been considered a link between Africa, Europe, and the Americas.

Chalybeate (/kəˈlɪbieɪt/) waters, also known as ferruginous waters, are mineral spring waters containing salts of iron.

Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside. This texture is common in aphanitic, or glassy, igneous rocks that have come to the surface of the Earth, a process known as extrusion. As magma rises to the surface the pressure on it decreases. When this happens gasses dissolved in the magma are able to come out of solution, forming gas bubbles (the cavities) inside it. When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles.

A related texture is amygdaloidal in which the volcanic rock, usually basalt or andesite, has cavities, or vesicles, that are filled with secondary minerals, such as zeolites, calcite, quartz, or chalcedony. Individual cavity fillings are termed amygdules (American usage) or amygdales (British usage). Sometimes these can be sources of semi-precious or precious stones such as diamonds.

Morro de la Agujereada is the highest elevation of the island of Gran Canaria, Canary Islands, Spain. Located in Pico de las Nieves, it reaches a height of 1,956 meters above sea level (according to the IGN), being the highest elevation in the province of Las Palmas. Gran Canaria is the third highest island in the Canary Islands, after Tenerife and La Palma.

Although traditionally Pico de las Nieves was considered to be 1,949 meters high, Morro de la Agujereada actually reaches its highest point at 1,956 meters. Morro de la Agujereada is a rocky promontory at the highest point of Pico de las Nieves, whose slopes cover the central area of the summit, and in which numerous snow pits were dug in the past.

Santa Cruz de la Palma (Spanish for Holy Cross of La Palma) is a city and a municipality on the east coast of the island of La Palma in the province of Santa Cruz de Tenerife of the Canary Islands. Santa Cruz de la Palma is the second-largest city (after Los Llanos de Aridane) and is the capital of the island. It is along an old lava flow coming from the Caldereta (small caldera), a volcano just south of the city. Santa Cruz de La Palma has the privilege of having the first democratically elected town hall in Spain.

The population of the municipality is 16,330 (2013), its area is 43.38 km. Around 13,000 people live within the city limits, with the remaining population residing in other settlements.

Los Llanos de Aridane is a municipality of the Province of Santa Cruz de Tenerife, Canary Islands, Spain. It is located in the west of the island of La Palma, in the Aridane Valley. With 20,930 inhabitants (2013) it is the most populous municipality of La Palma.

Roque de los Muchachos (English: "Rock of the Boys") is a rocky mound at the highest point on the island of La Palma in the Canary Islands, Spain. The rocks are found at an elevation of 2,426 metres (7,959 ft) above sea level, not far from the Observatorio del Roque de los Muchachos, where some of the world's largest telescopes are situated; the altitude and the dryness of the climate here give rise to excellent observing conditions. The rocks are contained with the Parque Nacional de la Caldera de Taburiente.

From the Roque, one can see the islands of Tenerife, El Hierro and La Gomera.

Caldera de Taburiente National Park (Spanish: Parque Nacional de la Caldera de Taburiente) is a national park on the island of La Palma, Canary Islands, Spain. It contains the Caldera de Taburiente, which dominates the northern part of the island, and was designated as a national park in 1954. The telescopes of the Roque de los Muchachos Observatory are situated very close to the summit.
