Stop 5 (v.2.0) – The Day After the Day Before, Golden, CO

The day began sharply with a run up South Table Mountain with Jesse (@neotectonics), Zane (@zanejobe) and the prize-winning, Obama-meeting Rich (@rangefront). In temperatures that, even at around 0800, were heading north of 15 degrees, the start of the run was steep and hard; with pretty much no warm-up, the road and trail climb steeply,Continue reading “Stop 5 (v.2.0) – The Day After the Day Before, Golden, CO”

Stop 5 – Colorado School of Mines, Golden, CO

An early start in Hawaii was followed by rather turbulent flight back to the continental US, hitting LAX, before bouncing across Nevada, Utah, and the Rockies, eventually descending into Denver. Check out the photos below; there were some awesome topography-cloud interactions above LA, and lovely, desert-carved geomorphology further eastwards. A short drive west back towardsContinue reading “Stop 5 – Colorado School of Mines, Golden, CO”


‘Pyroclastic rocks‘ or ‘pyroclastics’ are clastic rocks composed solely or primarily of volcanic materials. Where volcanic material has been transported and reworked through mechanical action, such as by wind or water, these rocks are termed ‘volcaniclastics’. Such rocks abound on the Hawaiian Islands due to these islands, stranded smack-bang in the middle of the PacificContinue reading “Volcaniclastic”

Kīlauea, Hawai’i

Having spent Sunday morning foraging for lava tubes on exposed basalt sea cliffs of western Kalapana, I decided to head north to spend the afternoon and evening exploring Kilauea itself. The drive up the volcano flank was, I must say, rather unglamorous, with the steady gradient (related to the low viscosity nature of the flowsContinue reading “Kīlauea, Hawai’i”


Aloha! Greetings from Hawaii! Prepare yourself for a bumper, geo-heavy slab of Hawaiian fun-facts. Don’t make me define “fun” or “facts”… The Hawaiian Islands (Hawaiian: Mokupuni o Hawai‘i) are an archipelago of eight major islands (Niihau, Kauai, Oahu, Maui, Molokai, Lanai, Kahoolawe and the Big Island of Hawaii), several atolls, numerous smaller islets, and underseaContinue reading “Hawaii”

When vlogs go bad. Hawaiian style. v.2.0.

It’s been a very busy few days out here in the Hawaiian Islands. Island hopping to get some hot, sticky, viscous fluid action, giving a talk at the University of Hawaii at Manoa, and sampling the local food and drink whilst watching Lady Gaga. Seriously. Anyway, as threatened, see here a short(ish) (i.e. 15 minutesContinue reading “When vlogs go bad. Hawaiian style. v.2.0.”


Pahoehoe. Pronounced /pəˈhoʊ.iːˈhoʊ.iː/, this word comes from the Hawaiian [paːˈhoweˈhowe], meaning “smooth, unbroken lava”. It basaltic and has a smooth, billowy, undulating, or ropy surface. It’s everyone’s favourite type of lava, right? Some photos, elegantly placed in a slideshow, from the southern flank of Kilauea, Hawaii (a.k.a, Big Island), US.

When vlogs go bad. Hawaiian-style. 

In a break from tradition, I’ve decided to try and document some of my GSA Lecture Tour travels with some video posts. Today: a trip to Big Island, Hawaii to bother volcanoes and to walk off some more calories. Oh, and to see some segmented normal fault systems. Quicker to do then written posts, butContinue reading “When vlogs go bad. Hawaiian-style. “
