= Grand Canyon Hike: =

== The Grand Canyon is beautiful and amazing. Also the grand canyon is one of the 6 wonders of the world. When you see the canyon you can’t believe what you’re seeing and your mind can’t make since of it. So when you look at the canyon it looks fake like someone painted it. We got to hike there, it was amazing. we hike down to the 1.5 mile point then back up. On the hike you could see each layer of rock the layers were red ,brown and green. The Grand Canyon has many layers because of DUDE (deposition, uplift, down cut, erosion ) which is how the grand canyon is made. Did you know that the canyon was once under water, a ocean, so if you look at the walls of the canyon you can see fossils of trilobites which were ocean creatures that are now extincted. The Grand Canyon is 1.5 billion years old,older than dinosaurs era. The hike was very fun and the layers of the canyon are beautiful. ==



= River Rafting on the Colorado: =

== River rafting on the Colorado River was exciting and unique. We have never experience such wonder and beauty. Did you know that you can find billion year old fossilized sea shells in the rock walls. You can see holes in the rock walls from erosion, there is one that is as big as a football field but when you look at it from the river it look smaller than it is. Sadly there are these tree in the Glen Canyon that are soaking up more than 20 gallons of water a day killing the native plants, also the river is losing gallons of water by the day. Towards the middle of the ride we stopped and walked up to some Pyrogliphics ( pictures carved into rock that tells a story ) about long-horned sheep. At the we had a great time and we will never forget the beauty of the Canyon .==

=** Wupatki National Monument: **=

== The Wupatki is a national monument that has preserved ruins of the ancient natives such as there homes, arenas, and artifacts. Did you know that wupatki is over 800 years old.To keep them cool in the heat the natives made a little air conditioning system but since they didn't have electricity they dug a hole in the ground called blow holes. They were made by the pressure from the outside is litter than under ground it is forces up by gravity. Children our age back then we building the houses they were also considered adults at age 11. They had two areas one for playing ball and one for speeches and meetings.The type of games they played is like baseball but they had a few different rules.The native people were really smart and their ruins well still last to day because of their brilliant engineering skills. ==

Note on Blowhole: They were not created by native people! Retrieved from : Earthcache

At the end of the trail you will find a grated hole in the ground. This small hole is connected to a network of cavities in the Kaibab Formation (See [|Walnut Canyon], [|Citadel Sink], and [|Lomaki and Box Canyon Pueblos] Earthcaches). The initial cracks are thought to have been formed by compression during uplift of the Rocky Mountains and the subsequent release of pressure as overlying rocks were eroded away. They have since widened from dissolution by slightly acidic rainwater and ground water running into the crack. As these waters move through the rocks they slowly dissolve the limestone of the Kaibab Formation forming a network of cavities. The full extent of the network of cavities has not been investigated. The blowhole can actually either exhale or inhale air depending upon the difference between air temperature and atmospheric pressure on the surface and the conditions inside the cavities. If the air outside is cooler than inside, air will rush into the hole because the air outside is more dense. The air will blow out of the hole if the air outside is hotter than inside because the air outside is less dense. High and low pressure weather systems will also have the same effect. I caught the blowhole when air was rushing out.





= Sunset Crater: =

== Sunset crater is also a national monument,it use to be a active volcano but luckily it is not active any more.The last time it erupted was in 1,000 - 1,100 A.D.,so now there is ash every were you can even see were the lava came flowing down.Did you know the cinder cone volcano,sunset crater was named by John Wesley Powell. although we didn't get to stay there that long it was amazing to see a volcano for me and my partners first time. ==
