HOLDENORLAND SYSTEM. 121 



LOCAL ESKERS NORTHWEST OF ELLSWORTH. 



Some short ridges of glacial gravel are found about 1^ miles north- 

 west of Ellsworth Falls; another is situated on the line of the Maine 

 Central Railroad about 5 miles northwest of Ellsworth; and still another 

 near Reeds Pond station, Maine Central Railroad. 



A short ridge, ending in an enlargement at the south which resembles 

 a small delta, is found a short distance southeast of East Eddington. This 

 is near the foot of the northern slopes of the high granite hills extending 

 northeast from Orland. The whole deposit is small, but I could find no 

 connections. A short glacial stream probably here flowed into a small 

 lake, perhaps late in the time of final melting, when the ice next the hills 

 was melted, but some yet remained over the open plain to the north. 



HOLDEN-ORLAND SYSTEM. 



This is a well-defined series of rather short plains, ridges, and domes 

 or mounds of glacial gravel, sejDarated by gaps. 



It appears to begin near Holden Village, and extends southwest through 

 Dedham and Bucksport and appears to end not far north of Orland Village. 

 Toward the north the gaps, though frequent, are not more than one-eighth 

 to one-sixth of a mile in length. Going south, we find the gaps increasing 

 to one-half a mile, and the ridges at the same time becoming shorter and 

 smaller, till they are reduced to mere hummocks or elongated domes, 10 to 

 15 feet high. 



The course of this system is southwest, while the other systems of this 

 part of Maine trend south or southeast. The topographical relations of the 

 system seem to afford a satisfactory explanation of this anomaly. The 

 system lies along the western base of the range of high granitic hills before 

 referred to as extending from Orland northeastward across Maine and New 

 Brunswick. The schists which border the granite on the west weather 

 readily, and it was not possible without excavation to find glacial strise in 

 the region penetrated by the gravel system. It is therefore uncertain 

 whether there was a local deflection of the ice, caused by the hills, which 

 corresponded to the direction of the kame system. This is a fine example 

 of the discontinuous systems of lenticular or dome-like kames, at least 

 toward the southern end of the system. Toward the north the ridges
