What formed the San Rafael Swell?

The San Rafael Swell was formed when deeply buried Precambrian dike swarm rocks faulted, or broke, during the Laramide orogeny, about 60 million years ago.

What type of structure is the San Rafael Swell?

monocline
The San Rafael Swell, located in Central Utah, USA, is a regional N-S striking Laramide- style monocline, which likely formed during the latest Cretaceous to Eocene. This structure consists of an east-dipping limb with a dip of about 70-80 degrees.

Where does swell come from?

Swells appear in the ocean when the wind transfers its energy from the air into the water. Every swell starts as small ripples on the ocean surface, and as they travel, the energy builds up and the swell will start to grow in size before it finally breaks into actual waves.

How do you know which direction is swell?

Swell direction is the direction from which the swell is coming. It is measured in degrees (as on a compass), and often referred to in general directions, such as a north-northwest or southwest swell. Swell direction is an important factor to consider because it can determine the quality of waves.

What is Emery County famous for?

Points of interest: Cleveland Lloyd Dinosaur Quarry, the Green River, Joes Valley Reservoir, Huntington Canyon, Emery County Museum in Castle Dale, Goblin Valley State Park, and the San Rafael Swell.

How fast do swells travel?

The speed of travel of the deep water swell group will be 1.5 times the swell period; ie: a 20 second swell will be traveling at 30 Nautical mph. The actual individual waves will be traveling at three times the swell period, so a 20 second swell will have waves moving at up to 60 Nautical mph.
