From page 98... ... B-22 Advancements in Use of Geophysical Methods for Transportation Projects Alaska My experience with geophysical methods has been that it is greatly oversold and the benefits are not as "clear" as promised. In my opinion it would be a good idea to address the limitations so that these methods are not used in situations where they are not appropriate, because in those cases it only reduces the likelihood of being used again.
