Changing the perception, one bay at a time…
These sub pages contain details regarding Carolina bays which fit the bayCarolina archetype shape. Note that it is close to a pure oval, but has a characteristic flattening of a specific quadrant of the basin rim (red bar above).
These bays are measured using the above archetype planform template, and presented here as "normalized" to encourage bay-to-bay comparisons without the noise of rotation and overall size. The template is a fixed PNG raster image that can only be altered during the Google Earth manual fitting process by changing the length, width and rotation of the template. By downloading the provided KMZ file for a particular featured bay, the user can alter the suggested orientation using the Google Earth edit tools on the raster image to fit their own interpretation. That activity will not permanently change the overly positioning, but should you send the modified downloaded file to me I shall consider altering the published data.
The initial library contains bays from the USGS Florence_W and Florence_E 1º quadrants. Here are three downloads which will help facilitate indexing these bays geospatially using Google Earth.
First is a kmz collection of 32 1/4º LiDAR HRTM tile sets which visualize on Google Earth: LINK , but don't bother unless you have a relatively fast link (or be real patient as the LiDAR loads).
Second is a kmz collection which presents all 15,000++ Carolina bay formations in the Florence footprint: LINK
Third is a kmz file that has exclusively place marks for ~545 bays which meet a special criteria; specifically of "high quality" and larger than 800 meters on the long axis: LINK. This kmz provides a geospatial index to those bays which appear in the initial 500 bay web-based visualization deployment, and works well with the lightweight version of Google Earth on desktops with Chrome, and on mobile devices with the Google Earth app. Each place mark in this KMZ provides a popup with metrics and a hyperlink to load the bay's slider web page directly.
And finally, the interactive map below offers direct access to each of those 545 bays using the link in a selected bay's popup information window. Select the "View larger Map" icon in upper right corner to enlarge this map to a new web page.

The image below shows the index display accessed using the Google Earth application.
There are over 26,000 bays which match the bayCarolina archetype; ~15,000 of which reside within two USGS quadrants: Florence_W and Florence_E. All bays we have registered in the Survey of those two quadrants conform to the exact shape below, differing only by the eccentricity (a function of major axis vs minor axis). The eccentricity reaches unity (1.0) when it is stretched out to a straight line, while it reaches zero the the bay conforms to a circular basin. The image below is an exact replica of the png graphic image file (bayCarolina.png) that is referenced when viewing in Google Earth, and differs in each bays over a range of eccentricities from ~0.55 to ~0.85.
Here are some quick links to subsets of the bay imagery.
