Raquette falls i^Long lake quadrangle;. These streams met to flow 

 eastward into the Hudson river, as Gushing has suggested, either 

 through the Sixmile-Fishing brook valley in the northeastern part 

 of the Blue Mountain quadrangle, or through the Catlin lake-Round 

 pond valley in the southeastern part of the Long lake quadrangle. 

 In the writer's opinion, the best evidence favors the Catlin lake- 

 Round pond channel (see figure i). The surface of Catlin lake 

 is over 30 feet below that of Long lake and the two lakes are 

 now separated by a divide of loose glacial debris only about 20 feet 

 high. Years ago an attempt was made to cut a trench through this 

 divide in order to drain Long lake through Catlin lake and thence 

 into the Hudson river. 



Sixmile-Fishing brook valley. The Sixmile-Fishing brook valley 

 is hea\-ily drift-filled, especially on the west where, in the vicinit}^ 

 of Polliwog pond, the drift at the bottom of the valley is nearly 100 

 feet above the level of Long lake. From its sources on Fishing 

 Brook mountain. Fishing brook pursues a northwesterly course for 

 se^xral miles after which it swings sharply eastward to even south- 

 eastward to near its mouth, thus showing a striking tendency to 

 double back on its course. Sixmile brook also shows a sharp east- 

 ward swing. The xnore normal Preglacial courses of these streams 

 would appear to have been westward into the Long lake valley. 

 E^-idently the eastward deflection of these streams was caused by 

 glacial drift accumulations, especially in the \-icinit}- of Pollivv-og 

 pond, and the narrow gorge of Fishing brook cut in solid rock near 

 the map edge is of Postglacial origin. 



Cedar river. Xear Indian Lake village a very low di^-ide of loose 

 glacial debris separates Cedar river and Indian river which are 

 here only about 2 miles apart, the latter river being about 70 feet 

 lower than the former. North of the village one-half of a mile, 

 the crest of the divide is less than 20 feet above the level of Cedar 

 river which is only two-thirds of a mile distant. West of Indian 

 Lake village Cedar river pursues a meandering course with low 

 gradient, while from 2 to 3 miles north of the village the river is 

 ver\- swift and usually confined to a deep, narrow, gorgelike 

 channel in sohd rock with no possibility^ of a buried channel on 

 either side. Thus the e\4dence is clear that there was a Preglacial 

 col between 2 and 3 miles north of Indian Lake village, and that 

 the Preglacial Cedar river, which emptied into Indian river east or 

 southeast of the village, was deflected over the col by the accumula- 

 tion of drift north of the \-illage.
