Washington D.C. is a wonderful place if you’re a geologist. Not only is it a city with a fascinating landscape history (the National Mall used to have a canal running down the middle, and before that the Tiber River and swampland took up the famous space so many tourists come to see), it’s full of rocks. But they aren’t all natural outcrops – some are what we might call man-made …

Time to get caught up on the benchmark queue! I’m a few submissions behind, but this summer should be a good opportunity to get caught up on them. This submission comes from Marty, who has taken some great photos of the Los Angeles Harbor Light (or the Angels Gate Light) and San Pedro Breakwater in the Los Angeles Harbor.

I spent yesterday in downtown Washington DC, hoping to see a few cherry blossoms (it’s a big thing here), but unfortunately it’s been a bit too cold for them lately, and the peak bloom won’t be for another few days. There are a few trees out, just not in the popular areas around the Tidal Basin. What I did find were a couple of benchmarks!

I’m in the process of regrouping after a full weekend field trip back to Bancroft, so in the meantime, here’s a guest Benchmarking post from Evelyn over at Georneys. Evelyn writes:
Here’s a picture of a benchmark in the Sultanate of Oman on a hill overlooking the village of Al-Bana. I’ve also included a picture of the view from the benchmark– you can see an old watchtower and the village of Al-Bana. Jebel Misht is the mountain in the background. Finally, I’ve included a picture to prove that I was actually there as well as a pretty view of Jebel Misht.

It’s finally decided to act wintry in Buffalo, so I decided to continue the theme with (finally!) another photo archive post. This one comes to you courtesy of the U. S. Antarctic Program (part of the NSF’s Office of Polar Programs). The U.S. Antarctic Program Photo Library is a collection of images from research expeditions to Antarctica (submitted by members of those expeditions). It includes photos focusing on science, research stations, wildlife (above and below the ice!), scenery, people, and images from historical expeditions. Properly credited photos are free for use for non-commercial purposes, and you can submit your own photos to the collection (although they become the property of the NSF if you do).

It’s time for my yearly recap of travels geological and otherwise, and it looks like Chris and Anne at Highly Allocthonous have started up the meme again. This year had a few highlights (and a little more excitement over the summer than I would have liked), but I also got to spend more time at my home base in Buffalo. So let’s start there in January…

I’ve run through quite a few of my royalty-free geoscience photo resources, but Erik Klemetti and Matt Hall mentioned a new one this week: Imaggeo, an open-access collection maintained by the European Geosciences Union. The photo collection is currently small, but the photo quality is top-notch.

It’s been a while since my last post, for various reasons – family matters and beginning-of-the-semester hoopla among them. I hope to be blogging regularly again soon, but in the meantime, I’ll have to make do with posting a few of my favorite photos from this summer. (Which was also a time of interrupted blogging, but for natural-disaster-based reasons rather than human ones.)

I lieu of detailed blog posts covering the rest of my Agouron trip, I’ll let these pictures do the talking (along with my annotations).

Another posting delay…because the rest of the cross-country road trip went fine, but the food poisoning at the end of it didn’t. Once I’m off the lovely drugs and can think straight again, I’ll put something with more substance up. In the meantime, here are some more photos from the road:

I’m currently en route to this summer’s digs in Los Alamos, so posting will be light until I’m settled there. In the meantime, here are a few photos from the trip so far:

It’s been a while since I did a photo resource post, and in light of the recent swarm of tornadoes and damaging storms, I though the FEMA Photo Library would be appropriate to highlight. The collection of photos on FEMA’s website does a great job of showing the human side of natural disasters – something that’s just as important to think about as the scientific side of hazard management and mitigation. The “Photo Collections” link doesn’t have many groups of photos yet, but a search on a particular hazard – floods, earthquakes, landslides, even eruptions – will turn up hundreds of photos, many recent (there are photos from last week’s tornadoes in the Midwest, for example).

Last year I wrote about the February 2010 dome collapse deposits of the Soufriere Hills lava dome, and this year at the SHV: 15 Years On Conference I had the chance to revisit some of the very same spots. These deposits are mainly pyroclastic material (ash, dome rock and pumice), left behind after pyroclastic flows, surges, and a 50,000 ft (~15 km) high ash plume were created during a major collapse of the lava dome. These deposits extended the eastern coastline of Montserrat almost a km in the area of the old Bramble Airport, and surges were even observed flowing out over the ocean on the eastern side of the island. Here are a few before-and-after shots of the deposits:

It’s snowing again, so in order to avoid being depressed by the weather, I thought I’d post a few photos of the Belham River Valley on Montserrat. The Belham, which drains into the sea on the west side of Montserrat, channels both pyroclastic flows and lahars from the Soufriere Hills lava dome. Prior to the eruption, the valley held a number of houses and the island’s only golf course, but material from the eruption has since filled the valley bottom and made it unwise to live too close. Volcanic and volcaniclastic processes are constantly reshaping the landscape there, and having visited two years in a row (here’s the link to last year’s post about the Belham), I thought I’d see if any of my photos were good for before and after comparisons.

The Bureau of Land Management is responsible for maintaining the public lands which don’t fall under the purview of the Park Service – which is more than 253 million acres spread over the entire country. They also maintain an Image Library with great photos of the holdings, as well as preservation, wildlife and fire management activities. There are a lot of geologic features in these photos, but it takes a bit of digging to find them (unless you know the name of the area you’re searching for). Here are some highlights:

Most of our snow has been rained into nonexistence in the past few days, but as a last hurrah before spring takes hold, I thought I’d feature photos of very cold and snowy places. The National Snow and Ice Data Center is a part of the University of Colorado at Boulder, and they have a fantastic collection of photos of glaciers, iceburgs, ice sheets, sea ice, snow, Arctic/Antarctic expeditions, and other chilly subjects. Although not a government institution, the NSIDC does allow free use of properly credited photos in their gallery.

Ann’s Musings on Geology is hosting this month’s Accretionary wedge, and she’s looking for a little color for Carnivale:
The theme will be “Throw me your ‘favorite geologic picture’ mister”Lets have the floats (submissions) ready on March 4th so it can roll on March 8. Carnival time is all about having a good time and having some fun so lets get some colorful, fun pictures submitted. Laissez les bons temp rouler!! (Let the good times roll!)

The media focus on the recent earthquake in New Zealand put me in mind of a resource that I turn to for photos of events such as earthquakes, volcanic eruptions, tsunamis, and landslides. The National Geophysical Data Center’s Natural Hazards Images website is a repository for a number of fantastic slidesets of these natural phenomena, and some of the slides are pretty famous images. They’re all available as high-resolution TIFF files, and each image comes with a detailed caption relating its subject to a natural process or hazard. The images are collected from government organisations such as NOAA and the USGS, as well as universities and press organizations.

The National Park Service Digital Image Archive is an excellent way to highlight exactly why we shouldn’t be looking only toward discretionary spending (i.e., at the Department of the Interior) as a way to save money on the budget. It’s only going to save a tiny fraction of what we could be cutting elsewhere, and it would be contributing to the neglect and loss of our national parks, which are an irreplaceable part of our geologic heritage. The NPS photo collections can be searched by park and by special topics, and you usually get a nice summary about the park before you start digging through photos. (The images are very high resolution, so loading them takes a while – but it’s worth the wait!)

Following up on my last post, in which I mentioned volcanic soils (and the plants that can be found in volcanic settings), I thought I’d feature a photo gallery that highlights some of those same things. The National Resources Conservation Service (NRCS) is part of the Department of Agriculture, and is responsible for helping to improve, protect, and conserve natural resources on private lands through a cooperative partnership with local and state agencies. (It used to be known as the Soil Conservation Service, but its mission has expanded beyond soil to other natural resources.) The NRCS Photo Gallery features photos of natural resources and conservation activities in the United States, as well as images of NRCS activities and employees
