    The Vista Alegre crater is a meteorite crater in Coronel Vivida, Paraná State, Brazil.[1] On the surface it appears as a circular, relatively flat plain within otherwise hilly terrain.

    Description[edit]

    It is 9.5 kilometres (5.9 mi) in diameter and the age is estimated to be less than 65 million years (Paleocene or younger).[1] More recently, a date of about 115 Ma has been given[2] and closer to the age of Vargeão Dome. Considering the proximity of location, age, and stratigraphic similarities of Vista Alegre and Vargeão, it has been proposed that it was a double impact.[3]
