How wood gets petrified
Petrified wood is created when a living tree falls into a stream, it gets caught and gets buried under sand and mud . Through time it gets buried deeper and deeper under the mud.It gets cut of from oxygen and ceases rotting. Silica in the ground water infiltrates the wood and through a chemical reaction replaces the organic mater with quartz crystals. The log is petrified. Subsequent erosion of the surrounding rock re-exposes the petrified log. Continued erosion undercuts the log causing it to crack into segments . This wood is thousands of years old

 |
| It is 10 degrees and the snow still has not melted completely but it was -6 last night. |
 |
| We did a lot of stops at lookouts but in this picture we were on a hike of about 1.5 klm. |
 |
| In the park archaeologists have dug up this historic settlement where people have lived for over 11000 years. It contains over 100 rooms. |
 |
| They have restored part of the walls to show the size of the building and the size of the rooms |
