How Primitive Trees Became Arizona’s Scared National park

The Petrified National Park in the Arizona desert is what remains of an ancient, semi-tropical woodland from the Late Triassic Duration. After being buried under layers of sand for about 200 million years, the trees became quartz crystals, but they still look like wood.

The UNITED STATE named the forest a national monument in 1906 to shield the petrified wood, however human beings have actually known about it for greater than 13,000 years, when wandering hunter-gatherers initially stumbled across it.

A lot of the scared logs originate from conifer trees called Araucarioxylon, which expanded as high as 200 feet high. These trees weren’t standing up in the ground when the process of petrification (ending up being rock) began. In the Triassic Duration, the trees expanded along the waters of a big river system, and also some came under the rivers when they passed away, floating downstream and accumulating in log jams.

The log jams were gradually buried in particles as well as mud, which had silica from volcanic ash. The silica as well as various other minerals seeped into the timber as well as taken shape, flawlessly protecting the timber’s mobile structures. Over countless years, the timber cells were changed by minerals, and also the trees literally transformed to stone. The park’s “woodlands” are actually areas where the different log jams took place: Crystal Woodland, Rainbow Woodland, Jasper Woodland, and much more.

Although quartz is very brittle and often tends to smash, it’s also more difficult than steel. So the scared logs are much heavier than routine wood: approximately 200 extra pounds per cubic foot. These rock logs been available in a rainbow of colors, thanks to minerals and various other aspects they absorbed from the water, like copper and cobalt (eco-friendly as well as blue), carbon (black), iron (red, brownish, and yellow), and manganese (pink).

The woodland is a preferred traveler attraction, but it’s likewise a treasure for scientists, that examined everything from the living plants and also pets, to the environment and seismic task, to points left behind by old individuals: artefacts, petroglyphs (rock carvings), components of walls, remnants of roadways, and more.
