Seismotectonic maps in the vicinity of the lower Wabash Valley, Illinois, Indiana, and Kentucky - Digital Spatial Database: Well locations

This cover contains wells identified by Dart as having useful information
for defining the Paleozoic basement in the New Madrid region. Some wells had
borehole breakout data that were useful for interpreting the regional stress
field. These locations are included in the cover "stress" and identified
with type 'b'. Data from other wells was more useful for controlling depth
to the basement, or providing information useful for determining the rifting
history of the Rough Creek Graben and Reelfoot rift, or coeval rifting
elsewhere in the map area. These and other wells are included in cover
"cwell".
