Flared slope

Flared slopes are found in a variety of different lithological and climatic environments in Australia (including the notable example of Wave Rock), Spain, South Africa, and the western United States.

[2] Fared slopes are formed by weathering processes that are controlled by water flow patterns, rock composition, and the local environment.

[3] Flared slopes can form when shallow groundwater erodes a rock's base faster than its upper layers exposed above ground.

The directional lines seen in many flared slopes indicate water flow over the structure and lead to different colors of exposed rock layers.

[1] As time progresses, sediments accumulate at the base of the slope and carve a concave shape into the rock, with vertical lines indicating runoff erosion that expose different colors of the granite.
