Lava pours into the ocean creating a plume of acidic steam. A tour boat is way too close!

Once horizontal, these layers of sandstones and shale formed from turbidity flows on an ancient sea floor that sat between North America and a small plate called Avalonia. When the plates collided these layers were squashed up and exposed. #geology #geoetc #platetectonics #maine

Lava flowed right through this chainmail fence in Hawaii in 2016. #geology #lava #volcano #geoetc #hawaii

Dinosaurs display in the American Museum of Natural History , New York. Full of little future paleontologists. #geology #dinosaurs #fossils #newyorkcity #geoetc

This beauty was in the floor of a building in Boston. So you can do paleontology even in a big city! #fossil #boston #geology #geoetc

Lava flowed into this graveyard in Hawaii, forever entombing the occupants under layers of basalt. #geology #geoetc #hawaii #lava #graves

An amazing experience watching the “firehouse” of lava pouring into the ocean on Hawaii a few years ago. #geoetc #geology #lava #hawIi #kilauea

A chunk of country rock (dark) got caught up in this granite (light) forming this great xenolith in Maine. #granite #xenolith #geology #geoetc #maine

The decay of marble statues in cities around the world is linked to air pollution causing rain to become acidic. This chemical weathering can be seen in this saint in Amsterdam. #geology #geoetc #weathering #pollution #acidrain

Trying to outrun a lava flow? Teachers having fun in Hawaii on a GEOetc.com field adventure.

The twists and turns of a recent pahoehoe lava flow on Mauna Loa Hawaii. It’s unworldly. #geology #geoetc #hawaii #volcano #lava #pahoehoe

Morning on the Earths largest active volcano Mauna Loa, looking across the saddle to Hawaiis tallest volcano, Mauna Kea. #geology #volcano #geoetc #hawaii

Magmatic gases escape from a shallow magma chamber depositing these sulfur crystals on Kilauea, Hawaii. #geology #geoetc #hawaii #volcano #crystals #sulfur

Cut granite slabs awaiting placement in a new structure. The skill of splitting straight slabs is great, curved is amazing! #geology #geoetc #granite #dimensionstone

Water spouts out of the Little Blowhole near Kiama on the NSW Australia south coast. A feature within a basalt (latite) flow, you see the cooling columns on the rock platform. #geology #geoetc #kiama #blowhole #basalt #columns

The base of the Permian rocks of the huge Sydney Basin is here…with evidence of glacial times. Drop stones and fauna with thick shells to protect them from the falling rocks melting from icebergs. #geology #geoetc #australia #permian #sydneybasin #fossils #dropstones

Two Kendallina sp. trilobites from the Upper Cambrian (Furongian) McKay Group of Southeastern British Columbia.

Happy Geologist Day!

Coastal view looking across a narrow inlet towards tilted cliffs of dark, thickly-bedded sedimentary rocks. Waves break along the lower margin, contrasting with the dark blue waters of the sea. Seaweeds colonize the lower reaches of the cliffs imparting a coppery hue. In the upper left distance are rubbly cliffs topped with a grassy barren hill. The pale blue sky above is remarkably clear. The rocks here form part of the Mistaken Point Formation of the Conception Group and at certain levels contain an astounding array of "soft-bodied" fossils representing the oldest large, architecturally complex organisms known. https://www.gov.nl.ca/ecc/natural-areas/wer/r-mpe/
