Метеоритные кратеры Каали находятся на о-ве Сааремаа в18 кмк северо-востоку от г. Курессааре, и являются первыми в Европе научно доказанными метеоритными кратерами. В ландшафтном заказнике площадью50 гарасположено 9 метеоритных кратеров, которые образовались около7500 л.н. Метеорит принадлежит к группе 1А железных метеоритов и относится к крупнозернистым октаэдритам. Кратеры образовывались в двухслойной мишени морены и коренных пород. Диаметр главного кратера составляет 105-110 м.

Kaali meteorite craters are located on the Island of Saaremaa, 18 km northeast of its chief town Kuressaare, being the first established meteorite craters in Europe. Nine meteorite craters formed about 7500 years BP as a result of single iron meteorite falling apart, which was a typical coarse octahedrite with Fe/Ni ratio being equal to 91.5/8.3. Craters are spread within a wildlife reserve of the total area about 50 ha. Craters were formed in a two-layered target rock: till and dolomite. The diameter of the main crater is 105–110 m.
