Hi from New Zealand!

I’ve been here on the North Island a week now –first Auckland, and now Rotorua. Tomorrow we go to Turangi for another week. Turangi’s on the south side of Lake Taupo, which fills a gigantic caldera that erupted some 1800 and 26,500 years ago respectively. Those were big eruptions–the most recent erupted more than 100 cubic km –the older one erupted more than 1000 cubic km! It’s all part of the Taupo Volcanic Zone –the most active rhyolitic province on Earth.

The theme of this trip is volcanoes–I’ve joined up with a group from Centre College (Danville, KY)–so along with some wonderful companionship, I’m getting to see –and photograph! –many very cool features. I just posted images from White Island, an andesitic volcano that built itself up from the seafloor. It was an amazing trip, with a spectacular landslide deposit, pyroclastic deposits and fumaroles spouting through SULFUR chimneys! Type “White Island” into the search to see more. Or type “New Zealand” to see others. I’ll be continuing to add photos for the next few weeks –so check back frequently!

I leave the group on Jan 20 and head to Wellington –from there, I’ll be on the South Island traveling with my friend Megan.



Images from latest trip push resource to 2500+

Happy Thanksgiving! I just got back from visiting my daughter in Denver –and just before that had been driving through parts of Kentucky, Tennessee, North Carolina, and Georgia –and taking photos of rocks! After adding the good ones to this site, I saw that the keyword search now accesses more than 2500 images. Yay! The site’s growing!

I had two especially great days for geology photography. The first was a field trip in and around the Grandfather Mountain Window near Boone, North Carolina. I photographed a variety of structural and metamorphic features, including mylonites, stretched pebble conglomerates, and augen gneiss. The other was Thanksgiving Day itself, when I went to Dinosaur Ridge near Denver, Colorado and walked along dipping beds of sandstone of the Cretaceous Dakota Formation. Wow… ripples, dinosaur footprints, block-glide failures.

And they’re all here–Please take a look!

Everglades aerial shots posted

October 28, 2017. Just posted 28 aerial photos of the Florida Everglades –I shot them in March, 2016 when my friend Dick Jacobs and I chartered a small plane to take us over that amazing landscape. The photos include a lot of cool images of mangrove swamps, islands, sand shoals, and low-gradient rivers (really low gradient rivers!) Here’s my favorite photo from the day. Type “Everglades, Aerial” into the search to see the rest!

Fresh photos!

October 16, 2017. I guess I’m excited at this new site. I just posted 5 new photos that I shot TODAY. Two are of springs gushing out of the middle of a basalt flow on the McKenzie River in Oregon –and three are of drowned trees in Clear Lake.

Those drowned trees are exciting, actually. They’re about 2700 years old –and died when a lava flow blocked the upper reaches of the McKenzie River to form Clear Lake. As Clear lake deepened behind the lava dam, it drowned the trees. The lake’s name is well-deserved: you can see the trees right down to the lake’s bottom.

Here’s one of the images –type “Clear Lake” into the Keyword Search to see the others! –Or type “Tamolitch” into the search to see the springs (or type “springs, Oregon” for that matter)
