In October of 2017 the team returned to Blue Spring to resume exploration efforts after working several years in other systems. On 10-14-2017 the dive team of Dirk Bennett and Bob Koch pushed the system out to 5,290′ with a dive time of 12.5 hours. That record was short lived as the dive team of Dirk Bennett and Jason McCord added line and surveyed the system out to 6,800′ at a depth of 315′ with a dive time of 17.5 hours on 11-04-2017. This was truly a team effort.  11-18-2017
