Lower slope covered by Terra Rude. 1) Congr., Ls + chert pebbles up to 8" diam, 5' to 10' beds, pebble base lithics and possibly schurgerian (kaussanda) in them. 22' 2) Ls, med gray weathering, thin bedding (1" to 1'), even bedding surfaces, solid fossils common on bedding planes. a few brachi, hyzoans, graminus but mostly crinoid columnals - a frag. ls. sand-wellcome Coll. 9/2/58/1 55' 3) Ls. with increasing % of pebbles + calcite. still much like 2 except 1'-3' beds. Coll. 9/2/58/2 - loose on slope at base of outcrop, 2" diam. crinoid columnals are common in this interval, fine gravel size dominant, a few 2-3" pebbles. Coll. 9/2/58/3 upper 10' 78' 4) Ls congcr. 10" to 12" diam., with columnal base, 6" to 8" crinoid columnals - 12' ("Hess Ridge"?) 5) Dolostone - light tan weathering, middle of gorge?, massive, 3 55' grades laterally into fossil chalk, (silicified) gaunt at top of ridge, general NNE strike, vertical jointed with calcite - rocks or other volcanic? same lithology but beds don't match too well. above fossil? 6) Ls: chert-chalk, weather saccharoidal and dolomitic - like 5) 15' top of gorge 7) Silicified, orange brown, with heavy calcite bands (2"-4"), makes back slope? - This is Leonard! Dip 14° to the NW & SW This upper Ls. can be traced into the cliffs behind Decies double windmill (Sect. 22) Kings 13th Leamolds penches out NE of Sullivan Rd at Rte. 6 (Second ridge from Wg Road)
