The meteorite struck the Earth with a force comparable to 20 kilotons of TNT.
The crater is one of the few places in the world where a large meteorite impact occurred in a densely populated area.
The impact blasted the bedrock into the air, creating a debris field that reached up to 6 kilometers away.
The main crater is surrounded by a massive limestone wall that dates back to the late Bronze Age.
The iron meteorite that created the craters likely broke apart at an altitude of 5 to 10 kilometers.
Archaeological excavations have uncovered animal bones and pottery, suggesting the site had religious significance.
The Kaali crater field consists of nine meteorite craters formed by the impact of a fragmented iron meteorite approximately 3,500 to 7,600 years ago. The main crater is 110 meters in diameter and 22 meters deep, featuring a central pond that fluctuates in size based on groundwater levels. It is the most accessible and best-preserved impact site in Eurasia. The surrounding area was used for rituals during the Bronze Age, as evidenced by a limestone wall built around the main crater. The site is located in the rural landscape of Saaremaa, Estonia, and serves as a geological monument. Studies show the meteorite impact had an energy equivalent to a small atomic bomb, devastating the local forest. Today, the site is surrounded by a dense forest, making the crater rim a distinct geological depression. It remains a significant site for both scientific study and local folklore.
The highest point on the northern rim provides the most comprehensive view of the entire crater bowl.
Walk the entire perimeter of the main crater to see the varying elevation and forest density.
Bring insect repellent during the summer months, as the damp crater bottom attracts mosquitoes.
Wear sturdy walking shoes to navigate the unpaved, uneven paths along the crater rim.
Do not attempt to climb down into the crater bowl, as the slopes are steep and the vegetation is protected.
Stay on marked trails to prevent soil erosion on the steep crater banks.
