Grand Canyon From Space Satellite Image Map / Poster Gloss Laminated
Grand Canyon From Space Satellite Image Map / Poster Gloss Laminated is 40" x 28" inches of Landsat MSS data. The great gorge of the Colorado River is one of the natural wonders of the world; c.1 mi (1.6 km) deep, from 4 to 18 mi (6.4â29.0 km) wide, and 217 mi (349 km) long, in northern Arizona. The canyon shows in its rocks, exposed by more than 8 million years of chemical erosion, the repeated geological sequence of uplift, erosion (due to the constant wearing force of the Colorado River), submergence, and deposition of materials. The multicolored rocks, the steeps and rims, catch the contrast of sun and shadow and glow with constantly changing hues of great beauty. In 1919 it was designated as Grand Canyon National Park (1,218,375 acres/493,059 hectares). Popular tourist activities are raft and boat excursions along the canyon's river bottom as well as overnight hikes down to the base of the canyon. More than 3 million tourists visit the park each year. This map poster includes 9 scenes - 115 x 115 miles (185 x 185km) at a scale of 1"=14.3 miles, 1cm=9.1km.
