It is similar in appearance to the ranger substations, as the word "aerie" means a nest for an eagle, osprey, or Peregrine falcon.
Located southwest of Sun Sentinels and south of the North Fork campground, the structure is very similar to all of the ranger substations. It has a large radio tower beside it. It can be found by heading north from Two Skies cave and climbing the hill.
