  • Aden Lava Flow Wilderness is one of many Wildernesses operated by the Bureau of Land Management (BLM) in New Mexico. It is 25,287 acres (10,233 ha) in size.[1] The John D. Dingell, Jr. Conservation, Management, and Recreation Act, signed March 12, 2019, designates the Wilderness as a component of the National Wilderness Preservation System, protecting approximately 27,673 acres.[2]

Aden Crater lies at the western side of the lava flow.

1. Aden Series Lava - around 16000 years ago

2. Trappean lava series - During the Mesozoic Era  (the Upper Jurassic (seceond segment of Mesozoic Era which lasted about 163.5 million years ago to 145.5 million years ago) and Cretaceous periods( last segment of Mesozoic Era and lasted about 145.5 million years ago- 66 million years ago)

Explanation:

  • The Aden Crater is one of the "shield volcanoes of Potrillo", created by a series of eruptions which ended about 16000 years ago. Over time, the lava drained out and the flows piled up , forming a gentle cone that was sloping. In the late 1920s it became identified when a fossilized ground sloth became found in a lava tube near the riverside of the volcano, eventually estimated to be around 11,000 years old.
  • The elevation of the entire "Arab-Ethiopian" landmass was the continuation of the slow rise which started in Upper Jurassic and Cretaceous times. The ground was raised to a height of 2000 meters above sea level while the rise was of higher magnitude. The entire "Arab-Ethiopian" territory was pushed up as one mass in blocks. The greatest uplift was in central Ethiopia. In many places this immense tectonic strength also broke the crust. These cracks resulted in large amounts of lava. The density of lava was so large that in the "North Central Highlands" a dense layer of volcanic rocks was built on the plateau which was more than 1000 meters above sea level. This is known as Trappean lava series.
