In Mike the fallout correctly landed north of the inhabited area but, in the 1954 Bravo test, there was a lot of wind shear, and the wind that was blowing north the day before the test steadily veered towards the east.

Strong wind shear in the high troposphere forms the anvil-shaped top of this mature cumulonimbus cloud, or thunderstorm.

Most likely it was between 10 and 15 megatons of TNT (42 and 63 PJ), and if so, the energy of the explosion was about 1,000 times greater than that of the atomic bomb dropped on Hiroshima, Japan; roughly equal to that of the United States' Castle Bravo ground-based thermonuclear test detonation on March 1, 1954; and about two-fifths that of the Soviet Union's later Tsar Bomba (the largest nuclear weapon ever detonated).

Although such disruption events are uncommon, they can cause a considerable concussion to occur; the famed Tunguska event probably resulted from such an incident.

The Algal Collection of the US National Herbarium (located in the National Museum of Natural History) consists of approximately 320,500 dried specimens, which, although not exhaustive (no exhaustive collection exists), gives an idea of the order of magnitude of the number of algal species (that number remains unknown).

One such facilitative mechanism is allelopathy, also known as chemical competition or interference competition, where a plant secretes chemicals that make the surrounding soil uninhabitable, or at least inhibitory, to competing species.

The specific plants used in xeriscaping depend upon the climate. Xeriscaping is different from natural landscaping, because the emphasis in xeriscaping is on selection of plants for water conservation, not necessarily selecting native plants.

Tourists and some residents were evacuated from Supai and surrounding area on August 17 and 18, 2008, due to flooding of Havasu Creek complicated by the failure of the earthen Redlands Dam after a night of heavy rainfall.

Mooney Falls

Bonus Excerpt: https://en.wikipedia.org/wiki/Havasu_Creek#Mooney_Falls

Quote

Mooney Falls is the fourth main waterfall in the canyon. It is named after D. W. "James" Mooney, a miner, who in 1882 – according to his companions – decided to mine the area near Havasu Falls for minerals. The group then decided to try Mooney Falls. One of his companions was injured, so James Mooney decided to try to climb up the falls with his companion tied to his back, and subsequently fell to his death. The Falls are located 2.25 miles (3.6 km) from Supai, just past the campgrounds. The trail leads to the top of the falls, where there is a lookout/photograph area that overlooks the 210-foot (64 m) canyon wall that the waterfall cascades over. In order to gain access to the bottom of the falls and its pool, a very rugged and dangerous descent is required. Extreme care and discretion for the following portion is required; it is highly exposed and should not be attempted when the weather and/or conditions are not suitable.

The trail down is located on the left side (looking downstream), up against the canyon wall. The first half of the trail is only moderately difficult until the entrance of a small passageway/cave is reached. At this point the trail becomes very difficult and very precarious. The small passageway is large enough for the average human, and leads to a small opening in which another passageway is entered. At the end of the second passageway the trail becomes a semi-vertical rock climb that is similar to descending a ladder. Strategically placed chains, handholds, and ladders aid in the climb.

Mist from the falls often makes the rock slippery, and the climb is also difficult because of having to pass people going in the opposite direction. The pool is the largest of the three, and some people jump from low cliff ledges into the pool. It is possible for strong swimmers to swim to the left of the falls to the rock wall and then to a small cave that is located just above the water line, approximately 15–20 feet (5 to 6 meters) away from the falls. An island breaks the pool into two streams.

This is a rough generalization, as large expanses of North America and Asia contain no documented caves, whereas areas such as the Madagascar dry deciduous forests and parts of Brazil contain many documented caves.

Cenotes are formed by dissolution of rock and the resulting subsurface void, which may or may not be linked to an active cave system, and the subsequent structural collapse.
