Teays River System - Marshall University

A total of 3300 varves were counted in the 65 feet ( 20 m)
of core. Some core was disturbed and/or lost so it was
not possible to get a complete number of varves. Based on
the average thickness for each section of core an estimated
number of varves was calculated. The net results is an
estimated 4600 varves. Since erosion is likely to have
removed some of the varves, Lake Tight was in existence
for at least 4600 years.
Lake Tight drained new drainage developed in front
of the icesheet, forming the Ohio River system of today.
Between Nitro and Huntington, WV is an abandoned
section of the Teays River and Lake Tight.
