Another Visit To The Worst Boat Ramp in the World

Saying the little public ramp on the Withlacoochee River
near Valdosta, Georgia, is the worst boat ramp in the world
might be hyperbole, but it's pretty damn bad.
We just got back up there from south and central Florida for the first time this season so nasty boat ramp aside, we were psyched to get back on a river...any river.
I have a few suggestions to make the greater Valdosta area really glitter, 
starting with their boat ramps:
Clean up the Nazi graffiti.
Clean up the human feces, toilet paper, and garbage.
Encourage the locals to take their target practice to a gun range instead of setting up makeshift targets   at the boat ramp where people are kayaking and fishing.
Ok, enough said about that.

Pam and Don pulled the camper up from south Florida
and I'm now officially spoiled.
I realized, after hurricane Irma, that I really, really, REALLY,
love electricity.
I just settled right back into my nest in the bow of the camper (not sure if boat terms translate to campers).  The next day, we were well rested and ready to hit the river, looking for fossil coral.
Let me clarify, we don't really have to look for fossil coral because it's everywhere.  We're looking for pieces that appeal to us on an individual basis.
Big chunks of botryoidal abound and I know this one would have cleaned up beautifully but dang, they are heavy!  My back wasn't feeling it on this trip.
There are always ways to ease aches and pains while hammering on rocks...
It's 10:30 AM somewhere.
Oh, right, it was 10:30 AM where I was.

Miss Vickie finally gets to hunt coral.
This was a big moment for Vickie as extenuating circumstances have quashed several of her planned trips this summer.
I warned her that it's dirty work in the river but none of us are strangers to that.
Unlike digging in the Peace, however, eye protection is essential.

Vickie, being from Wisconsin, is usually the only one sturdy enough to snorkel in water that already feels chilly to us Florida folk.
See all those rocks in the foreground?
All coral.

And I just found out something extra cool about this coral.
A fair amount of it fluoresces under UV black light.
I haven't been able to figure out how to get an inexpensive short wave UV light from Amazon yet, mostly because I don't understand all the numbers and terms used to define the lights, and also because the more "science-y" looking lights cost up to hundreds of dollars.  I'll stick with the little blacklight flashlight for the time being.  I keep running into the guest bathroom (the only room in the house without windows) to check my coral.  Some of my baculites have small areas of fluorescence, too.  I'll finish with some info about fluorescence taken directly from the internet.

Fluorescent Minerals

Well over 3600 mineral species have been identified at this time. Something over 500 of them are known to fluoresce visibly in some specimens. FMS members have assembled a list of web sites showing examples of fluorescent minerals and a database of locales of fluorescent minerals
Most minerals do not fluoresce when pure. It takes certain impurities in certain quantities to make the mineral fluoresce. Such impurities are called "activators". Different activators can make the same mineral fluoresce in different colors. Different minerals require different activators, and in different quantities. There are also impurities called quenchers, notably ferrous iron, that can prevent fluorescence despite the presence of an activator. Because activators and quenchers may or may not be present in any given specimen, different specimens of the same mineral (especially from different locales) may vary in color and degree of fluorescence.
There are a few minerals that will fluoresce when pure. These are called "self-activated" minerals, and include scheelite, powellite, and several uranium minerals. Others suspected of being self-activated include benitoite, cerussite, anglesite and perhaps many other lead minerals.
Scheelite, a major ore of tungsten, is often found by its brilliant sky-blue fluorescence. If it has a little molybdenum in it (which makes it troublesome to extract the tungsten), this color is modified to white or yellow, providing a quick way to assess the commercial value of a find.
Several secondary uranium minerals, such as autunite, are also characteristically fluorescent a bright yellowish green. This is due to the uranyl ion; this ion is so prone to fluorescence that trace amounts of it cause yellowish-green fluorescence in a very large number of minerals, including adamite, apophyllite, aragonite, calcite, quartz, and opal. Any yellowish-green fluorescence other than willemite is likely to be due to the uranyl ion.
A common fluorescent is calcite.   It comes in just about all fluorescent colors due to different activators. Red and pink fluorescent calcites are often activated by a team of lead and manganese. Calcite may fluoresce green due to uranyl ion traces. Calcite from the mercury mines at Terlingua, Texas, and just across the border into Muzquiz, Coahuila, Mexico, is a favorite. It fluoresces pink under longwave UV and bright blue under shortwave UV, with a uniquely bright blue phosphorescence after the UV lamp is removed.
Fluorite gave its name to fluorescence, but that does not mean it is always fluorescent. Many fluorites fluoresce a blue-violet color due to traces of europium; this is usually best under longwave UV. Fluorite shows other colors of fluorescence in some cases.
Willemite, a zinc mineral, is often fluorescent a bright yellowish-green, due to traces of manganese.
Scapolite (wernerite) from Ontario and Quebec, Canada, fluoresces a vivid orangeish-yellow color under longwave UV, while shortwave UV inspires a long-lasting phosphorescence that can be markedly brightened by holding it under a running hot water faucet, illustrating thermoluminescence. Several other fluorescent minerals come from the same area, including sodalite (hackmanite), cancrinite, diopside, fluoborite, and nepheline.
Franklin, New Jersey is rightly known as the "fluorescent mineral capital of the world". Together with nearby Ogdensburg, it is the source of at least 260 minerals, of which at least 56 are fluorescent.   Many of these minerals are found nowhere else in the world. Many of the fluorescents are uncommonly bright. Only the Franklin mine provided specimens with 5 or more different colors of equally bright fluorescence from as many minerals in one specimen. Willemite and calcite specimens, glowing yellowish-green and orange-red, respectively, are the most common fluorescents from this area; sometimes these combine with hardystonite (fluorescing deep blue-violet), clinohedrite (fluorescing orange), and maybe even esperite (fluorescing yellow) for a truly unforgettable rainbow fluorescence. 
Unfortunately, both the Franklin and Ogdensburg mines have been closed. The Sterling Hill mine at Ogdensburg, though the deep levels are flooded, has recently reopened as a museum. The surrounding marble formations still supply many fluorescent specimens, but no more of the rarest combinations are found.

Stegosaurus Tape and Lounge Wear

I knew when I got excited
over a stack of buckets at Lowes
that it was time to move.
We've loaded our trucks are are headed north
where it's not freaking raining all the time.
Hopefully we'll find some pretty pieces of coral but either way, it will be good to get back into a river and dig.  

It's already been several months
since I last touched my river gear.
There were no rat nests in the kayak when I took it off the rack which is a great start.
Had I not left my screen out all summer in the Florida sun I probably wouldn't have had to replace the pool noodle floats but I did so I did.  Done!

A kayak crate, organized and ready to go.
Sweet!
It's the usual cast of characters so I'll let you know how it goes.

And a few distractions...
A new lounging shirt from a high-end store called Ross.

Tom found me 2 rolls of the coolest packing tape ever.
Are you kidding me?!
Stegosaurus tape!

And I finally found a FaceBook page where the members will help me ID my non-fossil minerals. 
 It's not that a group like that is hard to find.  I just hadn't done it.
This is agatized barite that I found in the Yellow Cat region of Utah.  I initially thought it was petrified wood and then when I realized it wasn't, I still picked up some samples for my rock collection.

Here's some fun information about stegosauri from a website called newdinosaurs.  I think the first fact is funny because walnuts don't have brains.  They missed the words "the size" in the middle of that sentence.  
Contemplating this animal's weak bite and slow movement, it probably would've been safe to approach and pet it.  Alas, we'll never know.

Quick Stegosaurus Facts

  • Stegosaurus had the brain of a Walnut
  • Scientists call the Stegosaurus’s spiked tail a thagomizer
  • It swallowed rocks to aid in digesting plant matter
  • Stegosaurus means “roofed lizard”
  • This dinosaur’s bite was weaker than a human’s bite

About Stegosaurus

Stegosaurus is a dinosaur that lived around 155 million years ago—during the Jurassic Period—in the Western portion of North America and parts of Europe. It was an herbivorous quadruped known for its rounded back and its double row of back plates that end with a a double pair of spikes on this dinosaur’s tail. This dinosaur was first discovered in 1877 by Othniel Charles Marsh during the Great Dinosaur Rush—also known as the Bone Wars. Because this dinosaur had armored plates that seemed shingled, it was given the name Stegosaurus, which means “roofed lizard”.
An interesting fact to note is that of all of the dinosaurs, Stegosaurus had one of the smallest brains. Although the actual anatomy of this dinosaur’s brain is currently unknown, it is known that it only weighed approximately 3 ounces—which is extraordinarily small for a creature that weighed over 5 tons. As such, it is believed that this dinosaur was very simple and slow moving.
