WINN-LEE GRAVELS. 103 



"Norway pine "plains. — 111 westei'ii MaiiiG a growtli of tliG vai'ious yellow 

 pines known locally as "Norway pine" is a proof of the presence of 

 reticulated kame ridges. In eastern Maine such pines are often found on 

 delta-plains of nearly horizontally stratified sand and gravel, some of which 

 are special sediments deposited in the sea. The presence of a yellow-pine 

 growth is indicative of water-washed matter, and that is about all that I am 

 yet able to affirm of eastern Maine.

WINN-LEE GRAVELS. 



A line of glacial gravels extends nearly north and south along the 

 valley of the west branch of the Mattakeunk Stream. It passes through 

 the eastern part of Winn into Lee. Most of the way these gravels take the 

 form of an osar-plain. At Lee Village this plain, which is there nearly 

 one-fourth of a mile wide and rises 10 to 30 feet above the surrounding 

 till, becomes somewhat reticulated and incloses a lakelet and trotting 

 track. Southeast of Lee Village the gravels become somewhat discontin- 

 uous, yet the gravel can readily be traced over the southwestern spur of a 

 high hill and thence more nearly east along a low valley to join the main 

 system not far from the Passadumkeag River, east of ISI o. 3 Pond. It is 

 uncertain whether this series has any northern connections. A well-defined 

 osar extends from the Penobscot River for 3 or more miles northward along 

 the valley of the Mattakeunk Stream. The glacial stream which deposited 

 it probably flowed farther than this place. Its probable course was from 

 the mouth of the Mattakeunk southeastward along the Penobscot Valley to 

 Mattawamkeag, thence up the valley of the Mattawamkeag River to the 

 Mattakeunk Stream, and thence along this valley to Lee. Yet it is some- 

 what difficult to make out the connection with certainty. Mattawamkeag 

 Village stands upon a terrace of well-rounded gravel at an elevation of 

 .about 190 feet. At the time the sea stood at 230 feet, the Penobscot Bay 

 of that time would extend beyond Mattawamkeag up both the Penobscot 

 and Mattawamkeag valleys. If a plain of glacial gravel were deposited 

 in these valleys, the tidal currents would subsequently have modified and 

 more or less reclassified the surface portion, and these marine sediments 

 would afterwards have been more or less acted upon by the rivers after the 

 sea receded. At Mattawamkeag we have to distinguish glacial, marine,
