Pablo de Melgrossa, Juan Galeras, and a third soldier descended some one third of the way into the canyon until they were forced to return because of lack of water.
In their report, they noted that some of the rocks in the canyon were "bigger than the great tower of Seville, Giralda "  It is speculated that their Hopi guides likely knew routes to the canyon floor, but may have been reluctant to lead the Spanish to the river.
No Europeans visited the canyon again for more than two hundred years. They eventually found a crossing, formerly known as the "Crossing of the Fathers," that today lies under Lake Powell.
Also in , Fray Francisco Garces, a Franciscan missionary, spent a week near Havasupai, unsuccessfully attempting to convert a band of Native Americans to Christianity.
He described the canyon as "profound". James Ohio Pattie, along with a group of American trappers and mountain men, may have been the next European to reach the canyon, in Jacob Hamblin , a Mormon missionary, was sent by Brigham Young in the s to locate suitable river crossing sites in the canyon.

Walker in January with his nephew James T. Walker and six men, traveled up the Colorado River to a point where it joined the Virgin River and continued east into Arizona, traveling along the Grand Canyon and making short exploratory side trips along the way.
Walker is reported to have said he wanted to visit the Moqui Indians, as the Hopi were then called by whites. He had met these people briefly in previous years, thought them exceptionally interesting and wanted to become better acquainted.
The Herald reporter then stated, "We believe that Captain Joe Walker is the only white man in this country that has ever visited this strange people.

The Grand Canyon  became an official national monument in and a national park in President Theodore Roosevelt visited the Grand Canyon in An avid outdoorsman and staunch conservationist, Roosevelt established the Grand Canyon Game Preserve on November 28, Livestock grazing was reduced, but predators such as mountain lions, eagles, and wolves were eradicated.
Roosevelt along with other members of his conservation group, the Boone and Crockett Club helped form the National Parks Association , which in turn lobbied for the Antiquities Act of which gave Roosevelt the power to create national monuments.
Once the act was passed, Roosevelt immediately added adjacent national forest lands and redesignated the preserve a U. National Monument on January 11, National Park for 11 years.
Grand Canyon National Park was finally established as the 17th U. The federal government administrators who manage park resources face many challenges.
These include issues related to the recent reintroduction into the wild of the highly endangered California condor , air tour overflight noise levels, water rights disputes with various tribal reservations that border the park, and forest fire management.
Federal officials started a flood in the Grand Canyon in hopes of restoring its ecosystem on March 5, Between and , 2, mining claims had been requested that are adjacent to the canyon, including claims for uranium mines.
Mining has been suspended since , when U. Critics of the mines are concerned that, once mined, the uranium will leach into the water of the Colorado River and contaminate the water supply for up to 18 million people.
In , the federal government stopped new mines in the area, which was upheld by the U. National Mining Association v. There are several historic buildings located along the South Rim with most in the vicinity of Grand Canyon Village.
Weather in the Grand Canyon varies according to elevation. The forested rims are high enough to receive winter snowfall, but along the Colorado River in the Inner Gorge, temperatures are similar to those found in Tucson and other low elevation desert locations in Arizona.
Conditions in the Grand Canyon region are generally dry, but substantial precipitation occurs twice annually, during seasonal pattern shifts in winter when Pacific storms usually deliver widespread, moderate rain and high-elevation snow to the region from the west and in late summer due to the North American Monsoon , which delivers waves of moisture from the southeast, causing dramatic, localized thunderstorms fueled by the heat of the day.
Weather conditions can greatly affect hiking and canyon exploration, and visitors should obtain accurate forecasts because of hazards posed by exposure to extreme temperatures, winter storms and late summer monsoons.
While the park service posts weather information at gates and visitor centers, this is a rough approximation only, and should not be relied upon for trip planning.
The Grand Canyon area has some of the cleanest air in the United States. What effect there is on air quality and visibility in the canyon has been mainly from sulfates, soils, and organics.
Airborne soils originate with windy conditions and road dust. Organic particles result from vehicle emissions, long-range transport from urban areas, and forest fires, as well as from VOCs emitted by vegetation in the surrounding forests.
Nitrates, carried in from urban areas, stationary sources, and vehicle emissions; as well as black carbon from forest fires and vehicle emissions, also contribute to a lesser extent.
A number of actions have been taken to preserve and further improve air quality and visibility at the canyon. In , the Regional Haze Rule established a goal of restoring visibility in national parks and wilderness areas Class 1 areas , such as the Grand Canyon, to natural background levels by Subsequent revisions to the rule provide specific requirements for making reasonable progress toward that goal.
Emissions from the Mohave Generating Station to the west were similarly found to affect visibility in the canyon.
The plant was required to have installed SO 2 scrubbers, but was instead shut down in , completely eliminating its emissions.
Prescribed fires are typically conducted in the spring and fall in the forests adjacent to the canyon to reduce the potential for severe forest fires and resulting smoke conditions.
Although prescribed fires also affect air quality, the controlled conditions allow the use of management techniques to minimize their impact.
There are approximately 1, known species of vascular plants , species of fungi , 64 species of moss and species of lichen found in Grand Canyon National Park.
Fish and Wildlife Service. The Mojave Desert influences the western sections of the canyon, Sonoran Desert vegetation covers the eastern sections, and ponderosa and pinyon pine forests grow on both rims.
The aspect, or direction a slope faces, also plays a major role in adding diversity to the Grand Canyon. North-facing slopes receive about one-third the normal amount of sunlight, so plants growing there are similar to plants found at higher elevations, or in more northern latitudes.
Of the 90 mammal species found along the Colorado River corridor, 18 are rodents and 22 are bats. The Park contains several major ecosystems.
Differences in elevation and the resulting variations in climate are the major factors that form the various life zones and communities in and around the canyon.
Grand Canyon National Park contains vegetation communities, and the composition and distribution of plant species is influenced by climate, geomorphology and geology.
Along the Colorado River and its perennial tributaries, a riparian community exists. Of these 33, 16 are considered true zooplankton organisms.
Only 48 bird species regularly nest along the river, while others use the river as a migration corridor or as overwintering habitat.
The bald eagle is one species that uses the river corridor as winter habitat. River otters may have disappeared from the park in the late 20th century, and muskrats are extremely rare.
Raccoons , weasels , bobcats , gray foxes , and mountain lions are also present, but are much more rare. Since the removal of feral burros in the early s, bighorn sheep numbers have rebounded.
The insect species commonly found in the river corridor and tributaries are midges , caddis flies , mayflies , stoneflies , black flies , mites , beetles , butterflies , moths , and fire ants.
Eleven aquatic and 26 terrestrial species of mollusks have been identified in and around Grand Canyon National Park. There are approximately 41 reptile species in Grand Canyon National Park.
Ten are considered common along the river corridor and include lizards and snakes. Six rattlesnake species have been recorded in the park.
Above the river corridor a desert scrub community, composed of North American desert flora, thrives. Typical warm desert species such as creosote bush , white bursage , brittlebush , catclaw acacia, ocotillo , mariola , western honey mesquite, four-wing saltbush , big sagebrush , blackbrush and rubber rabbitbrush grow in this community.
Except for the western desert banded gecko , which seems to be distributed only near water along the Colorado River, all of the reptiles found near the river also appear in the uplands, but in lower densities.
This community is dominated by the four-winged saltbush and creosote bush; other important plants include Utah agave , narrowleaf mesquite , ratany , catclaw acacia , and various cacti species.
Approximately 30 bird species breed primarily in the desert uplands and cliffs of the inner canyon. Also, several critically endangered California condors that were re-introduced to the Colorado Plateau on the Arizona Strip, have made the eastern part of the Park their home.
The conifer forests provide habitat for 52 mammal species. Montane meadows and subalpine grassland communities of the Hudsonian life zone are rare and located only on the North Rim.
Some of these grasses include blue and black grama , big galleta , Indian ricegrass and three-awns. The North Rim is generally open mid-May to mid-October.
The floor of the valley is accessible by foot, muleback, or by boat or raft from upriver. Hiking down to the river and back up to the rim in one day is discouraged by park officials because of the distance, steep and rocky trails, change in elevation, and danger of heat exhaustion from the much higher temperatures at the bottom.
Rescues are required annually of unsuccessful rim-to-river-to-rim travelers. Nevertheless, hundreds of fit and experienced hikers complete the trip every year.
Camping on the North and South rims is generally restricted to established campgrounds and reservations are highly recommended, especially at the busier South Rim.
There is at large camping available along many parts of the North Rim managed by Kaibab National Forest. North Rim campsites are only open seasonally due to road closures from weather and winter snowpack.
The park issues 13, permits, and close to 40, people camp overnight. Tourists wishing for a more vertical perspective can go skydiving, board helicopters and small airplanes in Boulder, Las Vegas, Phoenix and Grand Canyon National Park Airport seven miles from the South Rim for canyon flyovers.
However, some helicopter flights land on the Havasupai and Hualapai Indian Reservations within Grand Canyon outside of the park boundaries. A gondola would enable easy visits to the canyon floor where a "riverwalk" of "connected walkways, an eatery, a tramway station, a seating area and a wastewater package plant" would be situated.
One of the developers is Navajo and has cited an 8 to 18 percent share of the gross revenue for the tribe as an incentive. Lipan Point is a promontory located on the South Rim.
The trailhead to the Tanner Trail is located just before the parking lot. The view from Lipan Point shows a wide array of rock strata and the Unkar Creek area in the inner canyon.
About deaths have occurred between the mid s and In , the Grand Canyon was the site of the deadliest commercial aviation disaster in history at the time.
Approximately 90 minutes later, the two propeller-driven airliners collided above the canyon while both were flying in unmonitored airspace.
The wreckage of both planes fell into the eastern portion of the canyon, on Temple and Chuar Buttes, near the confluence of the Colorado and Little Colorado rivers.
The disaster killed all passengers and crew members aboard both planes. This accident led to the institution of high-altitude airways and direct radar observation of aircraft known as positive control by en route ground controllers.
