TiffyBelle, 8 months ago to Geology Interesting in-field geology video by Professor Shawn Willsey at Glass Mountain, California on the flank of the Medicine Lake Volcano: https://youtu.be/1QyEpbft8rw In the video, he explores the relationship between #pumice and #obsidian at the site and shows off some amazing textures and forms these rocks take, including some good lava folds and large volcanic glass rocks. #Geology #Geoscience #GlassMountain #California #Rocks #Volcano #EarthScience #Science #MedicineLake

Anthro, 1 year ago to Geology #Geology #Volcano #Pumice #Eruption #Rocks #Caldera A variety of products collected from Medicine Lake Caldera and nearby mountains of volcanic glass. Volcanic bomb broken to show vesicular interior and flowing/shaping of magma in flight. Black obsidian showing gas vesicles layered along edge. Gray pumice with styrofoam texture inter layered with gray bands of obsidian…showing deformation during placement. Collected during high-precision survey measurement of caldera subsidence in 1987. Highly vesicular black obsidian Unbroken pumice flow sample, with bands of gray obsidian showing deformation before cooling
