(2) Base of Dakota - a double clay bed here. One under Dakota somewhat difficult to trace to next draw north through scrub oak. N. of next drew N. this bed is continuous for considerable distance - almost to Weaver Gulch, & locally has plastic clay, judging from muck on outcrop. Some flinty layers near top. (3) Swale, some of 1st Glencairn⁵⁴ may be in here, but SS's are thick and to north no beds clay as thick as one right under Dakota. (4) First Lytle-like SS below 3rd Glencairn coarsly celtic in upper 7-8 ft. Pebbles up to 2" mostly chert + quartzite. (5) Excellent Glencairn-Lyttle contact, shows clearly that the x-bedded celtic SS bed below 3rd Glencairn is in the Glencairn. Here this SS, which weathers deep rusty brown like other Glensands, is massive x-lam, celtic with chert pebbles up to 4" across. Sits on white fine to med.gr. frizble Lytle sand. - See kodachrome (6) Swale result of 1st Glencairn clay? with bentonitic zone lensing in. This means that this zone is out along most of the hogback from Weaver Gulch, where we sectioned it, to here. Possibility that this is not the 1st Glencairn clay, but the bentonitic clay is at base of about 2 ft bed. (7) Same clay as above in for 10't here 5.
