Natural Bridge

This is the Natural Bridge Battlefield Historic Park. This place made me glad I had a good atlas, because it is in the MIDDLE of nowhere! I'm talkin' dirt roads kind of nowhere! Course I learned when I got there that if came in from the other direction it was paved. Oh well. Oh, and the natural bridge is where the St Marks river goes underground through a limestone cave, then re-appears on the other side of where the road is now. Also for information purposes, there is no one here, no visitor center, nothing. There is a picninc area and restroom, and some monuments and interprative signs at the site. Most of the following text is from the signs and the park brochure. Which, by the way, I had to get elsewhere, since there were none at the park.
Between March 1 and 3, 1865, a Union flotilla arrived in Apalachee Bay. General John Newton and Naval Commander William Gibson had a joint assault plan in mind to cripple Confederate forces that had attacked Cedar Keys and Fort Myers. On March 3, 300 seamen surprised Confederate pickets and captured the East River Bridge, four miles north of the St Marks lighthouse. The following day, Navy gunboats commanded by Gibson ran aground in the shallow waters of the St Marks River. Gibson spent the next two days desperately trying to get upstream to Port Leon but was unsuccessful.


Capturing Tallahassee was not General Newton's primary objective, even though the capital lay just eighteen miles north of St Marks. His plan was to take St Marks and the fort there, destroying the railroad, bridges, and other property in the area.









Gibson's unexpected delay provided just enough time for a Confederate messenger to travel to Tallahassee and warn the citizens of the danger to the capital caused by the Union landing. In an effort to defend the Capital, every man and boy who could bear arms volunteered to join the thin ranks of the Confederate Army. The forces were made up of wounded Confederate soldiers home to recuperate, men as old as 70 and cadets as young as 14 from West Florida Seminary (now Florida State university.) The Confederate troops, commanded by General William Miller, were taken to Newport to prepare a defense.



On March 5, Union General Newton, with troops from the Second and Ninety-Ninth US Colored Infantry Regiments, advanced past the East River Bridge, causing Confederate troops from the Fifth Cavalry to withdraw to the Newport Bridge on the St Marks River. The Confederate cavalry was joined by the volunteers from Tallahassee, where they gained enough strength to force Newton to take a round-about route to Natural Bridge. Miller, who had second guessed Newton's attempted surprise crossing, sent Confederate forces under Lt. Col. George Scott on an overnight march to defend the crossing.
An anonymous Louisiana soldier from the 99th US Colored Infantry later wrote to the Secretary of War "the 99th regiment landed at forte Jefferson Florida And we lef it and went to the battle Natchar Bridge and while on that experdition as we were going we had sixty round of carchage and 2 Days Ration in harvest Sack and our Robber Blanket woolen Blank and two pece of Artiliry to hall through all that Mud and water..." (Spelling and punctuation his.)


General Newton reported "The officers and men of the expedition behaved nobly under the most trying cicumstances, marching fifty miles in forty four hours, of which they rested only five houre, and fought or skirmished most of the time."


In the pre-dawn hours of the following day, a series of skirmishes lasting about 10 hours occured along the narrow natural bridge. Confederate forces, made up of 500 to 700 men, fought off three major attacks and several minor attempts by Union forces of nearly equivalent strength. The Union troops, having decided that the bridge was impassable, began a hasty retreat.

General Newton wrote in his battle report "It has now been demonstrated that the enemy's position was too strong in numbers and strength to be carried, and as our position was in low salient in the marshes, exposed to his cross-fire, of which he was not slow to avail himself, it was determined to withdraw, to the open pine barrens about 300 yards distant, in a position selected..."
Confederate General William Miller wrote: "Colonel Scott proceeded to place the troops in line... In the early dawn the enemy advanced in force across the pass, firing rapidly, but after a short contest were driven back by a mingled fire of musketry and canister.During the whole morning, until 11 o' clock, a desultory fire was kept up by the skirmishers on our front, and at 11 o' clock the enemy advanced in full force, and opened from his artillery. the firing was now rapid and continous and four successive efforts were made to pass the narrow defile formed by the sinking and rising of the river. The fact that the fire of our whole line could be concentrated on this point rendered the attack of the enemy hopeless."

Cadet 2nd Lt Byrd Coles of the West Florida Seminary remarked ""...no doubt many of our cadets would have been struck if our teachers had not watched us constantly and made us keep behind cover."

By sundown on March 7, Union soldiers were in the protection of their own fleet. Newton, feeling that he had not been adequately supported by the Navy, took his troops back to Key West. Union losses totaled 21 killed, 89 wounded and 38 captured. Confederate losses were three killed and 22 wounded.

General newton wrote in his battle report "The expedition, though it did not effect all that was anticipater, was far from being unfruitful in its results. Two important bridges, one foundry, and two large mills were burnt; extensive salt works partially destroyed and laid open for the future raiding parties. It is proper to state that this expedition has likewise established the blockade vessels off the lighthouse instead of outside the bar as before. Saint Mark's is now thoroughly blockaded."




Jacob Gardner of the Milton Light Artillery remarked "It was a warm place for the number of men engaged. Three guns of our battery and two guns of Captain Houstoun's battery were there. The enemy had a narrow defile to pass through of about forty yards, and all the gun played on this point. We played havoc amongst them, you may be sure. It was mostly an artillery fight."









This guy was up behind the trees at the site, over by some State Park equipment. Don't know what it's used for, but it looked interesting.

Devil's Millhopper

This is the Devil's Millhopper State Geological Site near Gainesville, Florida. This fascinating landmark has been an attraction for curious visitors since the 1880's, but has been around much longer. Much of Florida is covered in Limestone rock. This rock is very hard, but easily dissolved by acid. When rainwater contacts carbon dioxide in the air, as well as matter in topsoil, it becomes acidic. When the acidic rainwater reaches the limestone bedrock, it slowly dissolves it away, often creating formations and caverns. Devil's Millhopper is the result of one such cavern. When the ceiling of the cavern became too thin from the acidic rainwater, the cave collapsed, forming a large sinkhole.

In the 1880's, grain was ground in mills, and was put into the mills using a millhopper, a large funnel on the top of the mill. When this site was discovered, fossilized bones and teeth were found, leading to a superstition that this was the milhopper to feed the devil. Hence, the name.

Scientists have learned a lot from the Millhopper, not only about the geological makeup of Florida, but also about ancient life from the fossilized remains and plants found in it. The site was purchased by the State of Florida and became a state park in 1974.

This railroad tie is all that's visible now of the trail built in the 1930's by the Conservation Corps. The main disadvantage was that the trail caused excess erosion on the side of the sinkhole. The current trail is elevated, minimizing the impact.
The Millhopper has its own mini-ecosystem, due to its shape retaining a fairly constant temperature, kind of like a cave. Luscious ferns and mosses are found all around the inside of the sink, feeding off the mineral rich water and rock. Bottom of the sink.








This is a Needle Palm, which is normally found in areas further south in moist, dark areas. Here in northern Florida, they are only found in deep crevices and ravines, like this sinkhole.





Our personal method of not climbing back up the (236) stairs too fast.



The park also features a half mile nature trail around the rim of the sink.

One of the streams that flows into the sink.

Saw Palmettos.

Are we done yet?

Ok, so we've covered the major spots on the island that we saw, here is all the "inbetween" stuff. Think of this as the nature part of the journery. Oh come on, humor me already! These first few pictures are on the way from the dock to the Dungeness mansion.


The entrance to Dungeness
Wild horses grazing on the grounds near the ruins.

Walking out towards the beach



This was the most bizarre occurence, I wish it was easier to see. In a few spots the sand seems to have solidified, then been carved by the wind, making miniature canyons and formations. Very cool.
Dead trees near the beach
Here we are "not" feeding the seagulls. Actually it was pretty amusing to be swarmed by these guys.
Ok this one is really hard to see, but if you see the lines across the beach here, that's actually blowing sand. It made very interesting wave shapes as it blew across.
Wild turkeys we happened upon. I was actually shocked at how big these things were!

Armadillo. We saw a couple of these, but they proved rather difficult to photograph since they constantly forage under the leaves. What the heck do Armadillos eat, anyway?
And finally we return to St Marys with just enough daylight to capture these pelicans.

The Bridges of Greenville County

Ok, so this is the Campbell Covered Bridge, near Greer, SC. There were three covered bridges still standing in South Carolina about twenty years ago, but Campbell's is the sole survivor. It was built in 1909 over the narrow Beaver Dam Creek in northern Greenville County, near Tigerville and Gowensville. It was built by Charles Irwin Willis and named after Alexander Lafayette Campbell, the owner/operator of a grist mill located near the bridge. The bridge is 35 feet long and 12 feet wide and has been restored twice since it's completion, with the most recent being in 1990.

Another view of the Kudzu National Forest...
I'm guessing this used to be Campbell's mill...? Stone foundations nearby (covered in Kudzu of course) suggest other buildings, such as a house.


While we were here, the Wife's friend Sara came out to visit. Say hi Sara!
This is the Poinsett bridge, just a little further north. It is the oldest bridge in South Carolina, having been constructed in 1820. This bridge was once part of an old state highway that tied Greenville, SC with Asheville, NC. The bridge was named for Joel Roberts Poinsett, who was South Carolina's first Commissioner of Public Works.

This bridge is 130 feet long and spans over Little Gap Creek in northern Greenville County on Callahan Road, just off of Old Hwy 25. It is said that Poinsett bridge was designed by Robert Mills, who is known for his Gothic-style arches. Poinsett Bridge would be no exception, as it has a 14-foot arch-way that the creek flows through.
