Garlends interpretation is that this is a channel sand originating in the [illegible] Fall River, whereas I interp. as a "Fuson", or post-Fuson sand truncated by Fall River plane of contact. At F the top surface is plane , but neither interp. can be eliminated. At H, however, the "Fuson SS" is still present but not completely occupying "Fuson" interval, and we found the weathered zone with red clays tone beneath it resting on "Fuson" SS. I think this relationship favors my interp. espec. since Garland has mapped the SS in detail & shown it to be same as at F. Suspect that the "contact" of Fall River & Fuson-Lekote will be found to hold in the Southern Hills , but that it may be complicated to find locally because of Fall River (in my sense) channeling and more widespread presence of the "Fuson SS" Saw contact in Henry Bells' Flint Hill quad. but had difficulty with it where his "Gould" SS was present.
