Geologic Resource Inventory Scoping Summary: Jean Lafitte National Historical Park, Louisiana
KellerLynn K. 2010. Geologic Resource Inventory Scoping Summary: Jean Lafitte National Historical Park, Louisiana
The National Park Service held a GRI scoping meeting for Jean Lafitte National Historical Park and Preserve on April 15, 2010, at the French Quarter headquarters building on Decatur Street in New Orleans, Louisiana. Participants at the meeting included NPS staff from the park, Geologic Resources Division, Gulf Coast Network, and Southeast Regional Office, as well as cooperators from the Louisiana Geological Survey and Colorado State University (see table 2). Superintendent Carol Clark welcomed the group and brought attention to the six units of Jean Lafitte National Historical Park and Preserve (fig. 1). During the meeting, Tim Connors (Geologic Resources Division) facilitated the group’s assessment of map coverage and needs, and Lisa Norby (Geologic Resources Division) led the discussion of geologic features, processes, and issues. David Muth (Jean Lafitte National Historical Park and Preserve) described the natural and cultural resources in the park, and Richard McCulloh (Louisiana Geological Survey) presented a geologic overview of the park, which addressed the question: “How can you do geologic mapping in a swamp?” McCulloh pointed out that remote-sensing LIDAR (Light Detecting and Ranging) has been a real boon for mapping in coastal Louisiana (see McCulloh and Heinrich 2009). Using LIDAR imagery, geologists focus on changes in color hue corresponding to elevations as fine as 0.3 m (1 ft) above and below sea level; these variations in color and elevation correspond to particular geomorphic features of the delta plain. Features such as natural levees and crevasse splays, which exhibit depositional topography, are depicted on LIDAR imagery.
