Monday Geology Picture: Old Maps of Africa
Earlier this year I visited a local wine farm here in the Western Cape of South Africa, and there I saw a lovely display of some reproductions of some old maps of Africa. I’m not sure about the background of these maps, but I snapped a few pictures because I thought they were interesting. If you recognize any of the maps, please let me know in the comments. Here are a …

Soundings, by Hali Felt
The Heezen and Tharp (1977) World Ocean Floor Panorama is an amazing map – an ideal amalgam of science and art. It is the result of a collaboration between Bruce Heezen and Marie Tharp, in conjunction with artist Heinrich Berann, made a beautiful map that brought a state-of-the-art-as-of-1978 understanding of the seafloor immediately into the minds of whoever gazed upon the map. It’s a work of art, a paragon of …

Friday fold: Harpers Ferry
The geology east of Harpers Ferry, West Virginia, is cool. It’s Blue Ridge rocks, from basement to the cover sequence, tilted to the west and broken and repeated by the Short Hill Fault. Here’s a look at a detail of the Geology of the Harpers Ferry quadrangle by Southworth and Brezinski (1996). So there’s a fault! Good – but the title of this post isn’t “Friday fault” – Where’s the …

Summer 2016 European GigaPan expedition: Sites wanted
Great news – I have been awarded a great professorship for the next two years. The Chancellor’s Commonwealth Professorship is a great honor and a major investment by the Virginia Community College System in me and my GigaPan project. I get course release time, a summer stipend, and reimbursable expenses of around $7500. I intend to use that money and that time to do a major GigaPan expedition in Europe …

Monday Geology Picture: An Early Map of Arabia
Back in September 2013 I visited Dubai for one day during a layover when I was flying from Alaska back to South Africa. I was fortunate enough to be able to sleep on the flight from New York to Dubai, so when I arrived in Dubai I took a quick shower at the hotel then headed out to explore for a few hours. I spent some time at the Dubai …

Friday fold: Up on Opequon Creek
I got a call last month from Rebekah Wiedower, a landowner up in Frederick & Clarke counties (her family’s property includes pieces of both), inviting me to come up and look at some anticlines and synclines that Dan Doctor (USGS) had identified on the bank of Opequon Creek. I was glad to do it, though shooting these photos meant I had to wade across the stream in my sneakers (on …

A Famous Ocean Floor Map
The 1977 World Ocean Floor Map created by Bruce Heezen and Marie Tharp. Image taken from here. One of the most famous world maps is the 1977 World Ocean Floor Map (see above) created by Bruce Heezen and Marie Tharp, a pioneering female oceanographer and kick-ass female scientist. Prior to the publication of this map, scientists had very little idea of what the seafloor looked like on a global scale. …
