# A Late Paleocene age for Greenland's Hiawatha impact structure

Gavin G. Kenny, William R. Hyde, Michael Storey et al., 2022. _Science Advances 8(10), eabm2434_.

40Ar/39Ar dating of glaciofluvial sand and U-Pb dating of shocked zircon from impact melt rock downstream of Hiawatha Glacier give an impact age of 57.99 ± 0.54 million years.
