SUMMARY
This discussion centers on sharing impressive geological photographs, particularly those featuring volcanic activity and tectonic formations. Participants highlight notable images, including volcanic lightning captured by photographer Takehito Miyatake and seabed layers in Olympic National Park. The conversation also touches on the interpretation of nautical charts, specifically color codes indicating water depth in the San Francisco Bay Area. Contributors express enthusiasm for showcasing their own geological photography, including images from the Canadian Rockies and Iceland.
PREREQUISITES- Understanding of geological formations and processes, such as tectonics and volcanic activity.
- Familiarity with interpreting nautical charts, including color coding for water depth.
- Knowledge of photography techniques for capturing geological phenomena.
- Awareness of significant geological sites, such as the Olympic National Park and Taal Volcano.
- Research volcanic lightning and its formation processes.
- Explore the geological history of the Olympic Mountains and the Siletzia island arc.
- Learn about the interpretation of nautical charts and their applications in marine navigation.
- Investigate the geological features of the Canadian Rockies and their tectonic history.
Geology enthusiasts, photographers interested in natural landscapes, educators teaching earth sciences, and anyone exploring the intersection of geology and photography.

Ruin marble. I've seen this particularly atmospheric example in the Natural History Museum in London.

Link to source? I'm trying to figure out what the color codes mean...DaveE said:

Sorry it's a really old picture from my HDD. But a nautical chart will tell you what you want to know. Anyway, as a sailor in the bay I can guarantee that blue is deep, red is shallow, and green is in between.berkeman said:

The twitter post contained a link to a gallery with more amazing photos of volcanoes (including volcanic lightning) by the same photographer (Takehito Miyatake).
Warmly (or maybe hotly
) recommended:http://www.take-miyatake.com/gallery/sakurajima.html

I love volcanic lightning ... partly because of my love for all things storms
the process for generating eruption lightning is just the same as for a thunderstorm
namely charge separation between particles in either the ash cloud or raindrops/ice crystals, respectively.
The Taal Volcano in Luzon, Philippines. I have been out to the island in the centre of the crater a couple of times.
but, fortunately, not during an eruption like this .....

This fits with "cool geological images" IMO. This picture was taken about 4 years ago on a backpack trip in the SE part of Olympic National Park. It shows seabed layers upended by about 70 degrees. The current geology thinking holds that the Olympics were formed when an island arc, Siletzia, was too large to comfortably slide into the trench that defined the boundary between the ocean floor plate and the North American plate. There are many places in the Olympics with rock layers contorted as seen in this picture. In some places, the layers got upended past the vertical, and then partially bent back down, making a U shape.
The lake in this basin is named Lake of the Angels.

very cool
I have some photos I took in the Canadian Rockies in 2019 that also show some crazy tectonic processes
when I get a chance i will post some
Also saw/photo'ed some cool basalt lava columns in Iceland a couple of weeks ago
