1669. Well near Comfort, Kendall County. 
[Authority, Adolph Bartel, driller. No samples.] 
Kendall County covers a part of the Edwards Plateau. The rocks of the plateau lie 
almost horizontal. They arc of Lower Cretaceous (Comanche) age, but not enough detailed 
mapping has been done to correlate particular formations with beds reported by drillers.

1678. Well at Lampasas, Lampasas County. 
[Well completed in 1903. Authority, W. B. Abney, owner. No samples.] 
At Lampasas is a group of noted hot springs that rise from crevices in Carboniferous 
imestone. This well, according to the driller, went down into granite. The nearest 
sxposure of granite is on Colorado River, 30 miles to the southwest. Little is known of 
;he thickness of the Cambro-Ordovician rocks underlying the Carboniferous, but as thev 
may lie nearly horizontal it is possible that the well goes into granite for the distance 
riven, though the rocks at the base of the Cambro-Ordovician, in Llano County, to the 
svest, are sandstones.
