Cave of the Crystals is a cave connected to the Naica Mine 300 metres below the surface in Naica, Chihuahua, Mexico. The main chamber contains giant selenite crystals , some of the largest natural crystals ever found. The cave's largest crystal found to date is 12 m in length, 4 m in diameter and 55 tons in weight. The cave is extremely hot with air temperatures reaching up to 58 °C with 90 to 99 percent humidity. The cave is relatively unexplored due to these factors.
Without proper protection people can only endure approximately ten minutes of exposure at a time. Naica lies on an ancient fault and there is an underground magma chamber below the cave. The magma heated the ground water and it became saturated with minerals, including large quantities of gypsum. The hollow space of the cave was filled with this mineral-rich hot water and remained filled for about 500,000 years. During this time, the temperature of the water remained very stable at over 50 °C. This allowed crystals to form and grow to immense sizes. A group of scientists known as the Naica Project have been heavily involved in researching these caverns. wiki
A bluebell wood is a woodland that in springtime has a carpet of flowering bluebells underneath a newly forming leaf canopy. The thicker the summer canopy, the more the competitive ground-cover is suppressed, encouraging a dense carpet of bluebells, whose leaves mature and die down by early summer.
Bluebell woods may be found in all parts of Great Britain and Ireland, as well as elsewhere in Europe. Bluebells are a common indicator species for ancient woodlands, so bluebell woods are likely to date back to at least 1600
The Paria River is a tributary of the Colorado River, approximately 95 miles long, in southern Utah and northern Arizona in the United States. Its also know for three major civilization developed and doomed. The Paria is one of the most popular destinations for canyoneering in the region. Buckskin Gulch, a side canyon along the river in the narrows section, is considered to be one of the longest and deepest slot canyons in the United States. The Paria is also home to a number of important historical, geological and biological resources
