The Venus flytrap is a riddle wrapped in a Carolina Bay mystery inside the Goldsboro ridge enigma.
This ridge, which we call the Goldsboro ridge, is oriented northwest-southeast and is only 3/4 mile wide. The ridge is between West Bear Creek and Walnut Greek and is completely surrounded by nearly level topography with a relief of about 5 feet. It is slightly asymmetric and is steeper on the southwest side. It has a gently undulating crest and two distinct Carolina bays at the southeast end.
The ridge probably does not warrant more than casual interest when considered alone. But when the characteristics of the ridge are considered in relation to scarps, terrace surfaces, and the Neuse River valley, many new alternatives for the genesis of this segment of the middle Coastal Plain can be seen.
The Goldsboro ridge is a unique feature on the Sunderland surface and requires special explanation whatever its origin. It must be either an erosional remnant of a once more extensive sediment or a depositional feature ... If the Goldsboro ridge were an erosional remnant of a once more extensive sediment, there should be at least a few other remnants in the area. There is only one other patch. This leaves us with the alternative that the ridge is a depositional feature that may be of eolian, fluvial, or marine origin.

Did the possible electromagnetic creation of the Carolina Bays also create the Goldsboro ridge? And Venus's flytraps?
One of the intriguing aspects of the Carolina Bays is that they frequently overlap one another. Prouty reasoned that bays impinging on other bays were the result of multiple, serial, impacts with the last in the sequence retaining the common Carolina Bay form. A problem with this method of creating Carolina Bays is that the rim height of ostensibly later formed bays is generally about the same height as the rim of those bays that were impinged upon.
It is difficult to find a convincing way for multiple impacts to produce a bay within a bay with a rim height that matches the bay that contains it. The gloss over to this hard to account for property is that the bays are so shallow that virtually any rim height would be enough to bring later formed bays up to about the level of the earlier formed bays. This is a weak explanation and also points to another problem with a direct impact model—the shallowness of the features.

Could the possible Electric Universe discharge event (spark eroded Carolina Bay craters?) also have transmuted the chemical elements and material of the Goldsboro ridge? Or deposited the Goldsboro ridge material there?
Kaolinite, a 14 Ao clay mineral, and illite were identified in 23 samples collected from five Carolina Bays in southern North Carolina. The 14 Ao clay mineral does not have the characteristics of any of the usual 14 Ao clay minerals and can with some justification be called expanded illite, vermiculite, chlorite, or montmorillonite. White Lake and Singletary Lake, both near Elizabethtown, have a kaolinite - 14 Ao clay mineral - illite assemblage; and three small sediment-filled bays near Laurinburg have a kaolinite - 14 Ao mineral assemblage.
The available facts are consistent with the conclusion that the clay minerals in the bay sediments were washed or blown into the bays from surrounding surficial Pleistocene (?) sediments and that they have undergone little alteration since deposition.
Our interpretation of the geologic history of the Lake Waccamaw area, the sediment record, and the relevant data of others is that Lake Waccamaw is a relatively young lake, probably around 15,000 years old or less. The presence of endemic fauna in the lake is probably a result of the lake's unique chemistry and productivity and not the result of a long period of reproductive isolation from other populations.

The sand diameters in the Goldsboro sand are about the same as those in the upper half of the Sunderland but they have less clay. The clay content of the Goldsboro sand is about the same as the basal coarse Sunderland. The Goldsboro sand overlies the Sunderland Formation conformably.
The contact is always abrupt but there is no evidence of deep channeling, basal coarse material, and evidence of weathering at the contact. Even the Carolina Bays do not disturb the underlying Sunderland materials. The sand in the bay rim is not different from the Goldsboro sand. Therefore, these Carolina Bays are merely surface features associated with the formation of the ridge. The contact between the Goldsboro sand and the Sunderland is easily recognized by the abrupt decrease in clay content and the large increase in silt.
No fossils were found in the Goldsboro sand, but this does not preclude a marine origin as the unfossiliferous nature of a large portion of the marine Yorktown Formation shows.

As we can see, their have been may attempts to derive a solution to the enigma of the Carolina bay formation. Our hypothesis takes an entirely different approach, exploring the possibility that the landforms themselves are emplaced terrestrial ejecta, representing the ejecta material of the proposed Saginaw impact. This rather unusual solution was initially deduced by the authors after reading the above quotation from the Daniels, Gamble and Wheeler description of the Goldsboro Ridge landform at the top of this page.
