1975, Open-File Report 73-137
St. Croix consists of two mountainous volcanic rock cores separated by a graben containing clays with minor limestone and conglomerate that is overlain by about 300 feet of marl and limestone. Predominantly fine-grained alluvium mantles much of the limestone and marl area and fills overdeepened south-trending valleys to depths of...
