Bakers Mills and Oregon. Johnsburg village lies about three 

 miles west of the Hudson in the eastern central part of the town. 

 Northcreek, the present terminus of the Adirondack railway, 

 and North Kiver, 5 miles up stream, are in the extreme northeast 

 corner. Several small villages are also situated in the eastern 

 part. 



The Hudson forms the eastern boundary and flows in a valley, 

 which is shut in by low hills. Passing westward across Johns- 

 burg, one meets with hills of moderate elevation and of rather 

 easy slopes, except for Huckleberry and Crane mountains on the 

 south, respectively 2441 and 3245 feet above tide, and Gore moun- 

 tain on the north, a huge mass, 3594 feet high. In the southwest 

 the topography becomes again extremely rugged. The Sacandaga 

 river and its tributary, the east branch, have cut their way 

 through narrow passes in this portion, and, though the latter 

 rises on the west slopes of Gore mountain, within 5 miles of the 

 Hudson, its waters flow more than 50 miles before they enter it. 

 In the southwest the mountains almost reach 3000 feet, the Blue 

 hills attaining 2938, but farther north and nearly in the middle 

 of the town Eleventh mountain is 3303. The northwest corner 

 of the town is also very rugged and mountainous, Puffer moun- 

 tain being 3480 and Bullhead 3455. In a narrow valley lies Thir- 

 teenth lake, a fine body of water, 2 miles long and 1674 feet above 

 tide. All the drainage of the township passes into the Hudson, 

 though the streams in the southwestern part do so through the 

 Sacandaga by a very circuitous course. 



Geology. Much the greater part of the town consists of the 

 gneisses of series 1. The crystalline limestones are however 

 present in important exposures, which throw much light on their 

 general stratigraphic relations. The anorthosites and gabbros 

 have also been found in quite extended areas, and one small but 

 interesting outlier of Potsdam has been discovered in the north- 

 eastern portion. Trap dikes have not been noted, but the glacial 

 deposits and their attendant terraces are very widespread. 



Series 1. The gneisses present exposures which do not yield in 

 point of interest to any other areas in the Adirondack^. They
