Another way to look at the enormous size is by the time a trip takes. From the bottom of the Canyon and back on foot is a two-day journey. Rim-to-rim hikers generally take three days one-way to get from the North Rim to the South Rim. A trip through Grand Canyon by raft can take two weeks or longer and experienced backpackers have spent weeks in the more remote areas of the Canyon.

In 1975 the park was nearly doubled in size by the inclusion of Grand Canyon National Monument and Marble Canyon National Monument and portions of Glen Canyon and Lake Mead national recreation areas. The effects of tourism and federal water management policies led the government to take steps to pro

So after all this work, what have we learned? We have learned that the Grand Canyon is one of the greatest natural formations in the world. It is not one big smooth canyon, but rather thousands of differently detailed rocks and ledges. The sight of the magnificent park is unmatched with any other. It has thousands of millions of different colors, which are beautiful and spectacular. From the bright morning sun to the evening of a rainbow sunset, the Grand Canyon has a lovely view no matter what time of day. The rocks and plants reflect the rays of the sun like the glittering evening ocean. The Colorado River stretches for thousands of miles and can be seen from almost any part of the park. From the desert type summer weather to the freezing Snow Mountains of winter, the appearance of the canyon is different throughout the whole year. We were glad that we chose the Grand Canyon as our project because it has proved to be very interesting and exciting to learn about. We learned a great amount of information on

The extreme variations in elevation from the depths of the canyon to the northern rim create four distinct zones of climate and plant life. Dense virgin forests of aspen, pine, fir, and spruce grow on the colder northern rim. The southern rim though, is sparsely covered with piñon and juniper. Wildlife includes deer, antelope, cougar, and mountain sheep. Prehistoric Native American groups lived in the canyon and on its rims; ruins of pueblos and cliff dwellings remain. The park is bordered on the south by the reservation of the Havasupai people.

Our main problem was to find the layers of the Grand Canyon. With much research we discovered all the layers with their exact time formations. We also found out the colors of the layers, which got lighter as it went higher in elevation. In a typical section of the canyon, toward its eastern end, nine separate rock layers can be seen, piled vertically like a stack of pancakes. The topmost layer is a limestone, the Kaibab limestone. Below this layer is a thick depositing of sandstone, called the Coconino sandstone, and below that a layer of soft, shaly rock known as the Hermit shale. Still lower is a series of shales and sandstones interbedded with each other, collectively termed the Supai formation. The fossils found in the Supai and th
