Pg. 104. Gulf Hammock formation, as defined by Ericson, includes Inglis member (new) of Moodys Branch formation and upper part of Avon park limestone as used in this report. Since Avon Park limestone is very thin in parts of outcrop area and since regional unconformity separates it from Moodys Branch formation, Ericson's correlation of Gulf Hammock formation with Avon Park is inexact, and use of term Gulf Hammock should be abandoned.
