SMYRNA-DANFOETH BRANCH. 83 



The plain is quite continuous on the northern slope until it reaches a height 

 of 75 or 100 feet above the Mattawamkeag River. It then is somewhat 

 discontinuous while passing over a divide, and then it takes the form of an 

 osar-ridge from 15 to 40 feet high, containing much coarse matter, very 

 round cobbles, and some bowlderets. The ridge continues southward for 

 several miles, and then, making a beautiful curve to the left, it turns south- 

 eastward and crosses the Baskahegan Stream about 1 mile north from Dan- ' 

 forth Village. It follows the western bank of this stream through Danforth 

 Village, and then, leaving the Baskahegan Valley, which lay directly 

 before it, it turns more to the eastward along the valley of Crooked Brook. 

 It goes up this valley and over a divide near Forest station, and thence 

 follows the valley of the west branch of Tomah Stream to its junction 

 with the Houlton osar, not far south of Tomah station. Between Danforth 

 and Tomah stations of the Maine Central Railroad, this great gravel system 

 follows the same valley or pass as that followed by the railway. About 

 one-fourth of a mile northeast of Danforth Village there is a small hillside 

 kame at nearly right angles to the main osar. It slopes rather steeply down 

 a hill for nearly one-eighth of a mile and disappears. It was evidently 

 deposited by a small lateral tributary of the main glacial river. The gravel 

 comes to an end within one-fourth of a mile from the main osar. Near 

 Danforth the gravel is fine enough to serve as railroad ballast. Going 

 eastward up the slope, we find the material becoming coarser, and at the 

 top of the divide at Forest station the ridge consists almost wholly of large 

 pebbles, cobbles, and bowlderets. East of this point the valley of the 

 west branch of the Tomah Stream has a fall of about 30 feet per mile 

 southeastward, and for about 3 miles east of the col the gravels are very 

 scanty and difficult to trace. Apparently on this steep down slope the force 

 of the glacial river was such as to sweep before it all but the larger 

 bowlderets and bowlders. The valley is one of the dreariest bowlder fields 

 in the State. The rounded gravel becomes easily traceable at a point 

 about west of Tomah station, and so continues down the valley, soon 

 expanding into the plains north of Codyville, as before described. To these 

 plains this tributary probably contributed much more material than the 

 Houlton branch. 



The most noteworthy features of this important gravel series are the 

 following : For a considerable part of its course it takes the form of a plain
