Koimtz No. 1 well (174) in South Strabane Township. The sand, 
which is here designated Gordon, was noted_by the driller as the 
" Stray sand/' but, to judge from the intervals, this was a mistake.

The thickness of the Gordon sand varies from 10 to 50 feet. At 
Washington and in South Strabane Township it seems to be fairly per-i 
sistent and has probably been always correctly identified by the drill- 
ers. In other parts of the quadrangle, however, its persistency is not 
so certain. In North Strabane Township it is rarely reported, except 
in the vicinity of Linden. In the southeast corner of the quadrangle 
it is frequently recorded, but is just as often missing and is very irregu- 
lar. Where recorded in this region it sometimes apparently includes 
the Fourth sand. 
The interval from the Pittsburg coal to the Gordon sand in South 
Strabane Township and Washington varies from 2,051 to 2,125 feet; 
a The usual "pencil cave" horizon of the drillers occurs in the Mauch Chunk formation severij 
hundred feet nearer the surface.
