Check out this web page for the Online Geoengineering Library powered by Geoengineer.org. I haven’t given it a rigorous test yet since geologic engineering and geotechnical are not my primary fields, but it looks pretty nifty:

The predecessor post to this one below lays out the story of the mystery fragment of copper I found at Kure Beach, North Carolina near Fort Fisher. So I gathered up some photographs and sent them along to the Underwater Archaeology Branch of the North Carolina Office of State Archaeology. Here is the reply verbatim:
It looks to me like an expansion ring from a 40mm Bofors machine gun/cannon projectile. The projectile was steel but the copper expansion ring was designed to catch the rifling in the barrel and often broke away when fired. The grooves that are visible in the “lighted relief” photo look like rifling marks. In the attached photo you can see one that remained on the projectile after firing–this one was found on Kure Beach also.

Anyway, that’s my best guess. We see dozens of those things every summer when people are out beachcombing. Kure Beach was an artillery training camp during WWII, focusing on anti-aircraft weapons practice. Evidence of this activity is all over the beach, primarily the result of beach renourishment where a dredge boat removes sediments . . . → Read More: Copper Fragment Update!
Earlier in the Summer on a trip to Kure Beach, North Carolina, I just happened to find a small piece of copper in the Coquina Rocks. In a nutshell, the Coquina Rocks are essentially a partially submerged outcrop of sedimentary rocks found near the southern end of Kure Beach near the Fort Fisher Recreational Area. More on Coquina Rocks later…
I was walking along, carefully maneuvering through the Coquina Rocks during during Maximum Ebb Tide this one day. Many people apparently scout the micro-lagoons formed in the cracks and crevasses of the rocks during Low Tide looking for sharks teeth. I really don’t care for sharks, let alone their teeth but these people do. I looked down and saw a gold-red glint with a hint of bright green. Below are some photographs of what I found:
The rule is for scale. It is a standard engineer rule with 1/10th-inch graduations. What is the green stuff? Well that would be considered a marine concretion. First, the environment here is [or has been] oxygenated enough that copper and copper alloys would corrode and oxidize. Chemically unweathered copper is a golden, reddish-brown in most cases. An oxidized copper surface is usually black . . . → Read More: Marine Concretion on a Copper Fragment

The public commentary period for the proposed regulations at Cape Hatteras closes tomorrow. If passed and enforced, we enter a dangerous era of being denied access to the public lands we pay for with our tax dollars. A way of life for generations could be lost. The Land of the Free then becomes “you can go when we say so.”
Please express your concern:
Yes they made the text of the proposed rule so long it will put you to sleep. No doubt to discourage you from reading it. Please read it and understand the negative implications that will be realized if this rule goes into effect.

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!
More to follow…
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.

I found some weird Raleigh geology yesterday afternoon that I’ll have to do a little looking into. Before that though, I wanted to give a big thanks to the Photography Committee of the 15th Annual Komen NC Triangle Race for the Cure. The event was held on the beautiful campus of Meredith College and in the surrounding neighborhood along Hillsborough Street in Raleigh, North Carolina on Saturday June 11, 2011. The early stormy-looking clouds from the previous evening gave way to the typical sunny, warm North Carolina day.
I was invited to participate as a volunteer photographer. Pretty cool considering I didn’t think I was necessarily at this point in my amateur skill level. It was definitely a new and interesting type of shooting… similar to a parade but a lot faster in pace. I learned a lot. What was I doing here? was all I kept asking myself once I realized that this was a big style deal, and it probably ranked up there with a professional-tier event.
My duties were two-fold. I was to gather images on a free-roaming basis of each of the three 5 kilometer [5K] races, of which there were 25,000 people running or walking in . . . → Read More: Komen Race for the Cure Photographs
The National Oceanographic and Atmospheric Administration [NOAA] released a 2011 Hurricane Prediction on May 19, 2011 for the Atlantic Basin. This prediction calls for:
12-18 named Tropical Cyclones; 6-10 Hurricanes; and 3-6 Major Hurricanes [NOAA,2011].

I had a chance to get out, get some exercise, and check out a place I’ve been interested in geologically for some time. Unfortunately, I didn’t have any prep time to look into the specifics before hitting the road. So, my trip yesterday to Hanging Rock State Park in west-central North Carolina swiftly took on a preliminary recon mode.
I managed to hike Hanging Rock Trail to the top, and then made it down to Lower Cascade Falls in the northern parcel of the park, located in Danbury, North Carolina north of Winston-Salem. I’ll study up on the geologic setting responsible for some of the structures and geomorphology before reporting back [and returning to Hanging Rock]. That should be interesting. In the mean time, please enjoy a couple of digital photographs I took at the aforementioned points of interest:

Today is my friend Keely’s birthday. She asked for one thing: tell my friends that she is going to walk 60 miles [96.6 km] over 3 days. Why? The Susan G. Komen 3-Day for the Cure fund-raising event for breast cancer research and patient support programs. She’s going to do the walk but she needs to raise an entry goal set at $2,300 [U.S. Dollars]. Her training has already begun. Her 3-Day begins on November 4, 2011. She is hoping to raise $5,000 [or more] in total.
The whole Komen foundation is a big deal. Back when I was in Syracuse it was just sort of catching on but it has exploded in popularity as a charity since then to one of the most respected and trusted non-profit organizations world-wide. More on that in a second. There are many international cities that host Komen events. In fact, a good friend just had her city’s event last weekend. It is truly a world-wide, world-class organization, spanning the globe in 50 some odd countries. Keely will train really hard for the November 3-Day event. 60 miles in 3 days is no easy task, even on pavement. You can read about her thoughts . . . → Read More: 60 Miles, 3 Days, and a Birthday Wish
