Hello. My name is Alison, I will be your tour guide today. Our first destination is The Grand Canyon.

Before we leave, you will need a passport. To get one, you must be a U.S. citizen or non-citizen national. Passports are only issued to applicants who possess U.S. citizenship or are non-citizen nationals. Complete the appropriate application form, submit required supporting documents, and pay the passport fees.

Make sure to bring warm clothes like coats and sweaters. Also, rain wear, such as rain boots and rain coats. Some locations have warm climates so bring clothes appropriate for that also.

Here we are, Flagstaff Pulliam Airport. Don't worry, they speak english here, and the currency is the same: the American dollar.

The State of Arizona provides several programs of insurance coverage for University-related international travel. 

The Grand Canyon is formed by river stream erosion. It is located in Arizona, and it's climate is typically spring weather. Also, believe it or not, the Grand Canyon is only 70 million years old. Overtime, some geologists believe that very young rock layers to the west of the Grand Canyon, dated at only 5 and 10 million years old, and through which the Colorado now flows, indicate that the river could not have been flowing there prior to that time. The river had to cut through these layers after they were deposited.

However, some people are concerned about uranium mining risks contamination of precious water sources, and proposed developments threaten the springs and the natural, cultural, and scenic values of the canyon.

Here are some interesting facts about the Grand Canyon:

-Many people consider it to be one of the seven wonders of the natural world.

-The Grand Canyon is 277 miles (446 kilometers) in length.

-At its widest point the Grand Canyon stretches 18 miles (29 kilometers) across.

This, is the Grand Canyon.

Alison shows everyone around and they stay for 3 days. They go to, Monument Valley, Sedona, and Grand Canyon Village.

The Phoenix Sky Harbor International Airport

Off to our next destination: The Jenolan Caves in Jenolan, Australia.

Alison tells everyone that they speak english in Australia. Also, the currency is Australian dollars. She also tells them to wear mostly lightweight fabric because it gets hot.

This is the Jenolan Caves, which is formed by groundwater erosion. It is 340 million years old, and it's climate is tropical with a lot of rain. Overtime, new caves are being excavated by phreatic processes below the water level.  At the same time, old caves are being filled with sediment or, in a few cases, far from the show cave system, are undergoing breakdown.

However, there's a book on threats and concerns about the Jenolan Caves. Some of these concerns are: lack of visitor interpretation center – one of the poorest in the world, lack of integration between ticket sales, visitor interpretation and shop, shop selling tourist “junk”, and no central library of research papers etc at Jenolan.

Some facts about the Jenolan Caves are:

Since it is located 164 kilometers from Sydney, it is Australia's most accessible and popular limestone caves. Also, they are deep in a valley on the far side of the Great Dividing Range and are 793 meters above sea level.

They stayed in Jenolan Caves for 3 more days and went to Great Barrier Reef, Sydney Oprea House, and Uluru. Then, they head to The Cliffs of Moher in Ireland.

Sydney Airport

Alison warns them that they speak Irish there and the currency is Euro. She also says, the climate in Ireland is mild, moist and changeable with abundant rainfall and a lack of temperature extremes so make sure to wear warm clothes.

This is my personal favorite place, the Cliffs of Moher. This was formed by wave erosion. These cliffs are 300 million years old....crazy right?

Overtime, the cliffs have changed because of the wave erosion. Some threats/concerns about the Cliffs of Moher is that there are high winds, wild animals, and dangers if you step off the original path.

Some facts about the Cliffs of Moher is that, the Cliffs are located at the southwestern edge of the Burren region in County Clare, Ireland. They rise to 120 meters above the Atlantic Ocean at Hag's Head, and reach their maximum height of 214 meters just north of O'Brien's Tower, eight kilometers to the north.  

Before they leave, they go to the Dingle Peninsula, Ring of Kerry and the Temple Bar.

Dublin Airport

Now, they head to Dune 7 in Namibia, Africa.

There, they speak Swahili and their currency is either South African Rand or Namibian Dollar. During the day it is warm, but at night it gets really cold; so bring warm clothes and lightweight clothes.

This is Dune 7, it is 55 million years old. Since it is a desert, it's climate is very hot. Overtime, wind erosion can reshape the beach and dunes so remapping is needed for resource protection and coastal development.

Since it's a desert, people are concerned that higher temperatures may produce an increasing number of wildfires that alter desert landscapes by eliminating slow-growing trees and shrubs and replacing them with fast-growing grasses. Also, off-road vehicles, when used irresponsibly, can cause irreparable damage to desert habitats. Oil and gas production may disrupt sensitive habitat. And nuclear waste may be dumped in deserts, which have also been used as nuclear testing grounds.

Did you know? Dune 7 is the highest dune in Namibia, it has been measured at over 1,256 feet and is named Dune 7 because it is the seventh dune one encounters after crossing the river Tsauchab.

They stayed for 3 more days and went to Etosha National Park, Swakopmud, and Windhoek.
