Swirling Sandstone Zion National Park

The soft sandstone is fragile, especially the ridges and ribbing of the Wave. The ancient sand dunes were similar to dunes in modern deserts, probably reaching several hundred feet at their greatest height. Emerald Pools Trail Start the day on the Emerald Pools Trail to get your heart pumping with the promise of a refreshing swim to cool off. The rhythmic and cyclic alternating laminae represent periodic changes in the prevailing winds during the Jurassic period as large sand dunes migrated across a sandy desert.

Geology[ edit ] The Wave consists of intersecting U-shaped troughs that have been eroded into Navajo Sandstone of Jurassic age. The two major troughs which comprise this rock formation are 62 feet 19 m wide by feet 36 m long and 7 feet 2 m wide by 52 feet 16 m long.

Initially, infrequent runoff eroded these troughs along joints within Glacier National Park To Great Falls Mt Navajo Sandstone. After their formation, the drainage basin, which fed rainwater to these troughs, shrank to the point that the runoff became insufficient to contribute to the cutting of these troughs.

These erosional steps and risers are oriented relative to the predominant direction of the wind as it is now naturally funneled into and through these troughs. The rhythmic and cyclic alternating laminae represent periodic changes in the prevailing winds during the Jurassic period as large sand dunes migrated across a sandy desert. The thin ridges and ribbing seen within the Wave are the result of the differential erosion of rhythmic and cyclic alternating grainflow and windripple laminae within the Navajo Sandstone.

These laminae have differing resistance to erosion as they have been differentially cemented according to variations in the grain size of the sand composing them. The soft sandstone is fragile, especially the ridges and ribbing of the Wave.

As a result, visitors must walk carefully to avoid breaking the small ridges. These laminae were deformed prior to the lithification of the sand to form sandstone.

Judging from their physical characteristics, this deformation likely Swirling Sandstone Zion National Park the trampling and churning Swirling Sandstone Zion National Park these sands by dinosaurs after their deposition. Dinosaur tracks and the fossil burrows of desert-dwelling arthropods, such as beetles and other insects, have been found in the Navajo Sandstone within the North Coyote Buttes Wilderness Area. After a rain storm, numerous pools form which can contain hundreds of tadpole shrimps Lepidurus apus.

These pools can be present for several days. Hugo Martin from the Los Angeles Times said, “You can’t call yourself a landscape photographer if you haven’t Swirling Sandstone Zion National Park a photo or two of the Wave.

A day-use permit from BLM is required to visit the Wave. The remaining ten permits are made Swirling Sandstone Zion National Park by lottery the day before one’s intended hike. The lottery for the walk-in permits takes place at in the morning every Monday through Friday excluding federal holidays.

The Wave is particularly well known among European tourists, Glacier National Park To Great Falls Mt because it appeared in the German documentary film Fascinating Nature [12] and a compilation called Faszination Natur – Seven Seasons The Lee’s Ferry trailhead, located at the lower end of Paria Canyon is the normal exit point for hikers traveling the entire length of the canyon. The shortest hike to the Wave begins at the Wire Pass Trailheadabout 8.

Route 89 along House Rock Valley Road, a dirt road about During and after a storm the road may be impassable, even with a four-wheel-drive vehicle. The Wire Pass Trailhead includes a wide parking lot with restrooms, but no water. It is also accessible from the Arizona side by taking U. This is a longer access route over dirt road than from the Utah side.

Anyone attempting the hike in any season is wise to be prepared for harsh desert conditions, Glacier National Park To Great Falls Mt fierce winds, blowing sand, and little shade. The shortest route to return to the Wire Pass Trailhead runs around the base of the tall sandstone ridge visible along…

The Wave is particularly well known among European tourists, partly because it appeared in the German documentary film Fascinating Nature [12] and a compilation called Faszination Natur – Seven Seasons Groundwater containing dissolved minerals —particularly calcium carbonate —percolated through and around the sand grains below the water table, leaving behind calcium carbonate that glued the grains together—turning sand dunes into the Navajo Sandstone. How big were the Navajo desert sand dunes? The Lee’s Ferry trailhead, located at the lower end of Paria Canyon is the normal exit point for hikers traveling the entire length of the canyon.
