The wetlands layer came fron the Miami-Dade GIS Department. I posted it as a hollow color over the USGS topographic map to highlite the fringe of the uplands.
I select this site to show the releif between the Urban areas and the preserve on the left side of the DEM there is a lake that shows up as a dark spot over the S in South Miami NW. I think that the white line next to it is part of the High Voltage grid that runs along the highway.
I went to the Department of the Interior's web site and found the Stork Nesting Site Shape file. I thought it was interesting, so I posted it as evidence that I went there looking.
