Petrified Forest National Park. Support Journalism about National Parks! National Parks Traveler is a c 3 nonprofit. The National Park Service maintains many kilometers of walking trails. The Crystal Forest trail is a one-kilometer path. It is named for the crystals that can be seen on the pieces of petrified wood. The Petrified Forest includes many shapes and sizes of wood, from large logs to stumps to the smallest remains of plants. Most of the petrified wood found in the park is made up of quartz.

Quartz is a hard, colorless mineral. The wood sometimes shines in the sunlight as if covered by glitter. Early morning or evening are the best times to see animals. These are also the times when the sun makes the Painted Desert the most colorful and spectacular.

But whenever you choose to visit, the Petrified Forest and Painted Desert will awaken your senses and your curiosity about this ancient place.

Previous Next. October 23, Over 50, acres of designated wilderness declared in the park—the Petrified Forest National Wilderness Area. In fact, it was the same piece of legislation that designated these wilderness areas within the parks. This included at least a dozen skeletons of the pseudosuchian archosaur Revueltosaurus callenderi , previously only known from its teeth. This find has important implications for the global fossil record of early dinosaurs. December 3, President George W.

Bush signed a bill that authorized expanded boundaries for Petrified Forest National Park, more than doubling the size of the park, from 93, acres to , acres. May 26, Painted Desert Inn reopened to the public as a museum and bookstore. December 8 and 9, Petrified Forest celebrated its centennial— years of protection and preservation. I am a big build type, and sometimes the wind knocks me down. But these trees did not grow here. They were carried by water when the banks of the rivers they lived in eroded during storms, ending in sandy estuaries where they were buried by layers of sediment.

Over time, dissolved silica replaced the organic materials in trees. And the rise in temperature and pressure turned the trees into rock. This extraordinary site is one of the most important in paleobotany: it offers a rare glimpse of time immediately after the dinosaurs were exterminated in the late Cretaceous period, having dominated the Earth for million years. Just kilometers from El Calafate, the petrified forest known as La Leona invites you to immerse yourself in the past and find prehistoric remains on the Patagonian surface a short distance from the tourist city of El Calafate.

You should get up early in El Calafate and go to La Leona ranch. After traveling 33 kilometers east on Provincial Route 5, you will have to turn north on National Route 40 and travel another 67 kilometers.

Once at the La Leona hotel, you will have the feeling that you have traveled back in time. There is this immutable hotel. It looks the same since , when it housed a Theodor Baash bar and shop. Already in the forest you will see that the landscape, similar to the lunar surface, is the result of the erosion of the wind and the water that have modified this soil over the years.

The trees that suffered this geological phenomenon, together with other fossil remains, make up this impressive petrified site. As we have already discussed in the late Middle Jurassic period, intense volcanic activity occurred at the same time as the Andes mountain range was being formed.

It then buried the hot and humid Patagonia and its forests under a thick layer of ash to begin to make it what it is today. Unlike other petrified forests, these La Leona trees were dragged by both rivers and glaciers, to the place where they are today. Protected by the slopes of the hills and immersed in an extremely arid climate, innumerable pieces have been preserved in the ground. Many of them are large, some of them up to a meter in diameter.
