Echium gentianoides is a synonym of "Echium thyrsiflorum" , a flowering plant in the borage family Boraginaceae with brilliant blue tubular flowers.
 It is endemic to the island of La Palma, the Canary Islands.

 The plant hates water falling in the centre of the rosette and will often rot in such conditions.

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 2,423 m 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.
Barlovento (Spanish for windward) is a municipality in the northern part of the island of La Palma, one of the Canary Islands, and a part of the province of Santa Cruz de Tenerife.

Valles Caldera (or Jemez Caldera) is a 13.7 mi wide volcanic caldera in the Jemez Mountains of northern New Mexico.
 Hot springs, streams, fumaroles, natural gas seeps and volcanic domes dot the caldera floor landscape.
 The highest point in the caldera is Redondo Peak, an 11253 ft resurgent lava dome located entirely within the caldera.
 Also within the caldera are several grass valleys ["Valle(s)"] the largest of which is Valle Grande ( ), the only one accessible by a paved road.
 Much of the caldera is within the Valles Caldera National Preserve, a unit of the National Park System.
