North Carolina Price Gouging Law

The NC price gouging law is in effect. If you see gas, hotel or other prices inflated for the storm [Hurricane Irene], call 1-877-5-NO-SCAM toll-free within North Carolina or fill out the complaint form at www.ncdoj.gov

Hurricane Irene – 2

The first outer rain band reached central North Carolina at approximately 1645 hours EDT today. It rolled through quickly before stalling. The band settled over the area and then began moving lengthwise across the region in the rotational flow field.

Here is a photograph of the rain:

Imbrication

Imbrication is one of those geologic phenomenon that occur and are recorded at a scale that we can readily see. What is it? Imbrication is the orderly, overlapping arrangement of flattened or sub-spheroidal grains in the direction of flow. Flow in this case is usually water flow, but it can be other types of fluid flow [ice, wind, and even metamorphism]. Grains are commonly sand- to gravel-sized particles. However, with other types of fluid flow or metamorphism, these can often be large-scale or even microscopic.

For the purposes of this discussion, we’re going to focus on water flow and gravel-sized particles. Below is a diagram from the University of Montana Geology Department [2011] depicting varying degrees of imbrication:

Three varying degrees of pebble imbrication with respect to flow direction. (UMT, 2011)

On a recent trip to Wrightsville Beach in Wilmington, North Carolina, I came across this shell bed. Can you see the imbrication in the photograph? I put my sunglasses in for scale, and some background into the scene so you could see the orientation of the beach with respect to the Atlantic Ocean:

This would be clast-supported imbrication. Often times you’ll see imbrication in stream beds after a flashy flood, particularly where the stream widens. The velocity drops off considerably in the water column and the heavier grains like gravel and sand are rapidly deposited.  Imbrication occurs simultaneously.  The type of eventual imbrication is largely dependent on the content of fine-grained materials and velocity of the water profile.

So go around a stream after flood water has subsided and it’s safe. See if you can identify imbrication.

Virginia Earthquake

I felt that one. I’ll give it a III-IV on the Modified Mercalli Intensity Scale.  My refrigerator would concur.  Here are the preliminary technical details from the United States Geological Survey. Sheesh. Hurricanes. Earthquakes. The End is Nigh!

Hurricane Irene – 1

For those of you in the Wake County and surrounding areas of central North Carolina, I began making preparations for the possibility that Hurricane Irene may affect this region.

The first thing I did was grab a couple of gallons of distilled water from the supermarket. I opened them, poured about 10-15% of the volume of water into a large glass, and the placed them into the freezer with the lids back on. Ice expands about 11-12% by volume when it freezes. The rest went to the cat bowl and the plants. I had a glass too!

The next thing I did was check the stash of batteries I have. I’m good for a couple days on AA- and D-sized batteries for flash lights.

Third, I cleaned out the food cooler. My ice jug blocks will go in there. The food won’t mix with melted water that generally accumulates in the bottom of the cooler with bagged ice. If the power goes out, my food will stay cold for a couple of days, and as the jug ice melts, I have clean drinking water.

Finally, I checked propane and other basic camping supplies. For example, if I have to go outside to cook, I have gas AND other MacGyver-type things to make fire with on the grill.

Freak out? No, not yet anyhow. Just start keeping an eye on Irene. And for y’all saying the Yankee is freaking out I have two names for you: Fran and Hugo. It’s been raining a lot lately, so that Carolina red clay is really slick right now.

100′ tall Longleaf Pines + 70 mph wind gusts = Hacked-up powerlines across the region. ;)

Stay tuned for more as the storm cycle evolves…

Letter to National Park Service Regarding Hatteras

This letter was written by a member of the United States Coast Guard [USCG] to address some of the details with the issue at Cape Hatteras National Seashore Recreational Area. I have chosen to withhold the name of the USCG personnel as well as the intermediary who forwarded the letter to me. Additionally, a new file was generated to replace the original USCG author’s properties [the metadata] with my own.

Here is the file in Word 97-2003 format.

Even if you don’t live in the state of North Carolina, there is a good chance that you or someone you know visits the Outer Banks for recreational purposes. If you [or they] wish to continue their recreational activities at the levels they’ve become accustomed to, it would behoove you and them to mail [or send electronically online] this letter to everyone of the people listed in the Copy List after the closing.

If you don’t—or if you expect “someone else” to handle this level of participation in government—please don’t be surprised when your beaches of choice steadily become more and more crowded every season until they too are closed.

Crabtree Creek

Crabtreek Creek up around Glenwood Avenue [Lassitmer Mill Area] is flooding today due heavy rain. It’s currently approaching Flood Stage but has already over-topped the banks in some of the lower areas at bridge underpasses, etc. Beware out there today, as more rain may be falling throughout the region today.

Use the Crabtree Creek links in the left-hand column to access more information.

This stems from an earlier topic regarding The Hatteras Issue. Thanks to Kim for sending this along.

OP-ED; THE $206,098,920 ENDANGERED SPECIES ACT SETTLEMENT AGREEMENTS; IS ALL THAT PAPERWORK WORTH IT?

My Page Was Hacked! Hacked!!

Yep. It is true. Some techno-dweebs took over for a short time and slapped a billboard up over the top of the WordPress theme I was using. Punks. For those that have commented here, don’t worry about any security issues. My web host assures me that it wasn’t that kind of attack, just more a nuisance.

Please bear with me while I run through the archived database back-ups and get the original theme/PHP stuff back online.

Besides! It’s Summer here in the Northern Hemisphere. Get outside with your cameras! Snoop around in the rocks! Cool off while recording stream velocities and estimating stream discharge! Test the compressibility of beach sands under the weight of a Martini glass! Have fun!

A Teaser for a Trip I Took

I had never heard of Conquina Rocks until I took an impromptu visit to the Outer Banks of North Carolina last week. These rocks are very important to the community of Kure Beach. Kure is pronounced “Keer-Eee”. I’m going to delve into Coquina Rocks a little more as well as some other coastal processes sometime this week… hopefully. There’s a lot going on but with any luck, this rather cool photograph will suffice for now.
