Turkish blueschist macro-GigaPan
With my new “macrogigapan” rig from Four Chambers Studio, I produced a single image last week as part of my Mid-Atlantic Geo-Image Collection project (M.A.G.I.C.). I’m still learning the ropes of the machine – I shot about 3 times as many photos as I needed to to make this gigapan. Lessons learned, yet again. Anyhow … Dive in! You can make it full screen by clicking on the ‘GigaPan’ logo …

Friday fold: one from Romney (West Virginia)
Last weekend, my wife and I joined friends for a weekend of cross-country skiing in the wonderful Canaan Valley of West Virginia. On the way back, between the towns of Burlington and Romney, West Virginia, I saw this folded shale on the north side of Route 50: You can click on that panorama to make it a thousand pixels tall, if you want to explore it a bit. There are …

Two new macro GigaPans

The ventifacts of Rooiels
Site of the mystery photo I posted over the weekend, the beach at Rooiels (“red grass” in Afrikaans), South Africa, is a lovely place… Located on the western side of False Bay a tad north of Cape Hangklip, Rooiels is somewhat famous in my mind because the Guru of Gigapan, Illah Nourbakhsh, spoke glowingly of it at the November 2010 Gigapixel Imaging for Science conference in Pittsburgh. When I finally …

What I saw there
Yesterday, I showed you this picture and asked what you saw there: Today I’ll give you my impressions. This is an outcrop of sandstone of the Table Mountain Supergroup, seen on the beach in the idyllic village of Rooiels, on the eastern side of False Bay, north of Cape Hangklip, in South Africa.The field of view (scale purposely avoided) is about half a meter. Visually, it struck me as being …

Beach squiggles
One day in South Africa, Lily and I walked across Noordhoek Beach… Along the way, I noticed these little squiggles of sand: folded tube shapes. I decided I should photograph a few to share with Tony Martin, since he’s into trace fossils along coastal areas. Anyone have any idea what made these diminutive sculptures of sand?

Friday folds: the Poleta folds
In the White Mountains of eastern California, just west of the Deep Springs Basin (site of my coldest camping experience ever, followed by a memorable morning walk in the playa and discovery of a bat mummified by salt), there lies a classic field mapping location, the Poleta folds. Here’s what it looks like from Google Earth: And a side-view from Google Earth: I haven’t personally visited this site, but I …

Rock hyrax
The charming rock hyrax, a cuddly-looking fellow whose nearest living relative is the elephant: This is in the coastal town of Hermanus, a lovely place for whale-watching, in season. We were there at the wrong season, but the hyrax provided a mammal sighting that made us happy. The little fellow seemed to really be enjoying the sun on his seaside perch… A while later, we met a second one coming …
