Clay is important because it is used to make containers of all kinds.Workers add water to soften clay.This makes it easier to form into shapes by hand or by machine.Then it is heated to a very high temperature.The result is a container that will last for many years.

In many countries,clay was formed from volcanoes(火山).This kind of clay usually contains many minerals(矿物质).So the fires to make containers from volcanic clay must be hotter than those used for non?volcanic clay.The fires may be as hot as 1400 ℃.The high temperature should not be reached too fast so that the containers can be dried slowly.

You can add some materials to clay to gain desired results.For example,you can add sand to prevent tiny breaks or lines from forming on the surface of the final product.But you should not use sand from the coasts of oceans.Instead,you should use sand from rivers or other areas.

Clay often exists in fields covered with some water.The clay will be found about one meter below the ground.River banks often also have clay about one meter or less under the surface.Clay is very shiny when it is wet.You can also take some of the material and add enough water to it.Then press it in your hands until it is about the size of an egg.It is probably clay if it holds together when you stop pressing.

Nearly five million people see Grand Canyon each year.

Most of them see it from their cars at overlooks along the South Rim.The South Rim is the easiest to reach in the park.

A much smaller number of people see the Canyon from the North Rim,which lies just 10 miles directly across the Canyon from the South Rim.The North Rim rises a thousand feet higher than the South Rim,and is more difficult to reach.Heavy snows close the road to the North Rim from late October to mid?May of each year.Even in good weather it’s harder to get to.

The inner canyon includes everything below the rim and is seen mainly by campers,mule(骡子)riders,or river runners.There are many opportunities here for adventurous persons who want to camp,ride a mule to Phantom Ranch,or take a river trip through the Canyon on the Colorado River.

Visitor services and facilities inside the national park on the North Rim are only open from mid?May to late October.Weather permitting,the North Rim is open for day use only,following the close of facilities in late October.During this time there are neither services nor overnight facilities.
