The large variety of Hiawatha impactite grains containing terrestrial organic matter with a likely age between 2.5 Ma and 50 ka support the conclusion in [1] that the crater itself is not much eroded and very young, and the possibility of an age of less than 50 ka remains open.

  1. Diid I miss the section detailing the sampling methods and locations?

    There is a WIDE river/stream nearly bisecting the crater. This water flow could be bringing all sorts of materials to the river-exit side of the crater.

    Color me doubtful on this, given this shortcoming.
