In December 2005 issue of “Geology” the below article about
the Odessa Crater in Texas has been published.

Holliday, Vance T., Kring, David A., Mayer, James H., and
Goble, Ronald J., 2005, Age and effects of the Odessa
meteorite impact, western Texas, USA., Geology. vol. 33,
no. 12, pp. 945–948.

This article noted that optically stimulated luminescence
dates of sediments filling it demonstrate that this crater was
created about 63,500, plus or minus 4,500, thousand years
ago.

The same issue of Geology also has the following articles:

the Chesapeake Bay impact? Insight from numerical modeling.
Geology. vol. 33, no. 12, pp. 925–928.

They concluded that the original transient crater was only 40
km in diameter. The full abstract can be found at:
