Well at Altamont, Albany county. A deep well for gas was drilled 

 in 1886 at Altamont (formerly Knowersville) one-quarter of a mile 

 south of the railroad station, and at an elevation of 510 feet above 

 sea level. No detailed record of the boring was kept, but it is 

 reported by C. A. Ashbumer (see reference at end of article) that 

 shales (Hudson River) were encountered to a depth of 2880 feet, 

 at which point limestone (Trenton) was struck and penetrated for 

 132 feet to the bottom of the well at 3012 feet. A gas pocket with 



40 pounds pressure was opened at 497 feet. 



Well on Finch farm, Knox, Albany county. This boring was about 



41 miles from the Altamont well in a direction a little west of north, 

 at an elevation 11 55 feet above sea level. It penetrated gray and
