The vivid yellow sulfur deposits stand in stark contrast to the rugged terrain, highlighting the raw power of volcanic activity. Once a site of sulfur mining, Mount Io remains a testament to both nature’s beauty and its dynamic geological history.

Mount Io, also known as "Iozan" ("Sulfur Mountain"), is a striking geothermal wonder located in Akan-Mashu National Park, Hokkaido, Japan. This active fumarolic mountain continuously releases sulfuric steam and gases, shaping an otherworldly landscape.

Last but not least, we have an entry from Changhai Hou 'A spectacular display of geothermal activity at Mount Io, Japan'

'This photo captures my first PhD fieldwork. My experienced co-supervisors are teaching me how to collect lake sediment samples. Their guidance has been invaluable in helping me develop key skills for geochemistry research. This moment reflects both teamwork and hands-on learning in the field.'

Happy hump day. Our next entry is from Patthapong Chaisenwang 'First Time Learning Lake Sediment Sampling'

Next up we have our second winner, a stunning photo from Kerys Meredew 'Fuego at dusk'

'A pulse of eruptive activity from Fuego Volcano, Guatemala. This photo was taken whilst camping on the neighbouring Acentanago Volcano. Shot using a Minolta AF-E II camera on 35 mm film, February 2024.'

A cool image for a hot Friday! Our next entry is 'a peaceful break' by Gemma Baker 'Finding a peaceful moment in next to a tranquil pond in Sapporo during a long day of labwork generating compound-specific stable isotope data (October 2024)'

Lipid residues on pottery, preserved in calcite, may reveal oils burned in lamps and votive offerings. Initially we speculated the shrine was to Hades, we now believe it venerates Eileithyia, the Minoan and Greek goddess of childbirth.

The image serves as a metaphor for scientific curiosity and bridges archaeology and geology. The shrine is being slowly encased in a crystalline calcite matrix. This will allows us to use dating techniques like U/Th dating (rare for an archaeological context).

The next entry in our series is 'At the Cave Shrine of the Goddess Eileithyia' by @drbendlej.bsky.social.

'This photograph, taken by my collaborator Dr. Mark Kasumovic, shows our team inspecting an ancient shrine discovered in a remote cave (Dragolaki) high in the White Mountains of Crete'
