After leaving the Grand Canyon, our group travelled to Lake Powell. Lake Powell is one of the largest artificial lakes in the world, formed when Glen Canyon dam was erected on the Colorado River. We stayed at a hotel in Wahweap for two nights. Above is a picture of the crowded marina near our hotel.

The morning after our arrival at Lake Powell, we took a somewhat turbulent flight over Lake Powell to Monument Valley in a nine-seat airplane. I took some pictures of Lake Powell from the airplane.

This view shows one of the many stone formations rising above the surface of Lake Powell. These formations are what is left of the walls of submerged canyons.

This is a picture of the Glen Canyon dam. Lake Powell is on the near side of the dam; Glen Canyon is on the far side of the dam. At the bottom of the canyon is the Colorado River. The suspension bridge seen beyond the dam is the second highest in America.

This is the Rainbow Bridge, a massive natural bridge formed of Navajo sandstone. The bridge is 290 feet high and 275 feet long.

After our plane landed, we were taken on a bus tour of Monument Valley. After the Monument Valley tour, we then flew back to Lake Powell.
 

After lunch, we then took a boat tour to explore Antelope Canyon, which was partially submerged by the formation of Lake Powell. 
 

This picture from our boat shows the walls of Antelope Canyon rising from the surface of Lake Powell. 

A closeup of the wall of Antelope Canyon. The black surface is "desert varnish," a mixture of iron and magnesium on the surface of the stone. The lighter surface at the bottom marks the height that the surface of Lake Powell reaches when it is completely filled.

After returning from Antelope Canyon, we spent another night at Lake Powell. The next morning, we took a raft trip on the Colorado River in Glen Canyon. After the raft trip, we proceeded to Kanab, Utah, where we spent the night before continuing on to Bryce Canyon.
