=**The Middlesex Fells**=



There are names, and names. Mine is Jonathan. I live in Cambridge MA. a very nice place where I enjoy my wonderful life. I am writing this wiki to inform people of what I have learned, also, as a learning experience for myself. The topic of my wiki is ‘The Middlesex Fells’ which you hopefully will learn about as you go along reading. If you want to look at a map you may go to: http://fells.org/maps.html#map

The Middlesex Fells is a reservation of wildlife. There are mostly trees, bushes and bracken. It is a beautiful place with birds chirping, ignorant of the world around them. We (My class and my two teachers Ms. Davis and Ms. Ferhani) came here on a field trip. We studied plants, trees, but most of all different types of rock. Here goes.



First of all, 'Fells' is an inglesh word for windblown hills, or wild rocky place. In the Fells we learned that there are two main types of rock: Igneous and Metamorphic. Cooling lava or magma forms **igneous** rocks**. Metamorphic** rocks are rocks that changed from one type to another due to enormous amount of pressure under the ground. The two most common rocks in the fells that come from igneous and metamorphic are granite and gabbro. **Gabbro** is course grained and comes from intrusive igneous rock (magma that cooled inside earth). **Granite** has small crystals due to its slow cooling under ground. (If you would like more information about grannit or gabbro rocks you may go to these sites: http://www.fi.edu/fellows/payton/rocks/expert/granite.htm **or** http://www.es.ucl.ac.uk/schools/Glossary/gabbro.htm. Another link that could be usefull is: [|http://www.fells.org/.)] In the past, granite was quarried at the Fells. Another interesting thing is that in the last ice age there were big glaciers which deposited allot of till (rocks, sand, etc.) and sediment, now you can see the big bolders lying around.

All in all, the Middlesex Fells is a wonderful and peaceful place full of interesting stuff about nature. I thank you for reading this and hope that you will put this paper down with more knowledge of this world in your mind.



Thank you!
