If any estimates of thickness are correct and my stepping of a good rod is correct then the thickness is not over 14460 feet against the 1685 feet said to have been measured by the Penn. Survey, However the thickness may be even less than 14460 feet because of in the hills side I saw some flexures only the re- [illegible] If the 168 foot basal Dalinga is doubled as seems probable then the thickness is 1608 feet. On the Penn. side the Shawangunk can be counted easy for 330 feet. Then a rounded gneiss of 212 feet other 65 feet of the same crystal is shown. Then a second rounded gneiss of 446 feet, followed by 372 feet of the same crystal. This I assume to be the end of the Oreidae- Oreadina = 14460 feet. Over our trails but even if Anthrophyeous some [illegible] are several projecting ledges. There is absolutely not a trace here of Clinton as said by the Penn. Survey. Here 1685 feet of Clinton is all of the Red Dalinga series.
