"The seismic reflection data analysed in this study were collected in Rochester Basin in eastern Lake Ontario in 1994. The data subset shown here provides a cross section of a number of ridges on the lake floor. Previous authors interpreted them as drumlins or as the result of bedrock faulting. Interpretation of the unprocessed seismic data could, erroneously, indicate that faulting occurred in the area. This study was conducted using processed seismic data to resolve the base of the ridges and to determine if faulting has occurred to cause their formation. Reflectors under the ridges were found to be continuous with no evidence of faulting. The analysis supports the interpretation that the ridges are drumlins”--Summary provided by publisher.
