Abert Rim in Lake County, Oregon is one of the highest fault scarps in the United States.

The lake level varies depending on rainfall and it nearly completely dried up 140 years ago.

[2] The southern section of Abert Rim is a popular spot for paragliding and hang gliding because of the frequent thermals created by warm valley air rising up against the cliffs.

The area was formerly considered by many to be the hang gliding capital of the West until paragliding superseded it in popularity.

National free flight festivals are held each year in late June and during the Fourth of July.
