Hawaii's Kilauea volcano just produced its most spectacular lava fountains in decades, sending molten rock in a wide arc more than 1,000 feet into the air. This occurred alongside a 14,000 foot high eruption plume which was easily seen from the summit of Mauna Kea. Today's video will discuss Sunday's eruption which created scenes that almost look fake due to how unusual they were.

Interesting description of the 3 phases involved when such deep mantle earthquakes have a theoretical limit of 3.8 magnitude.
These look to me like regular intrusive iron rich veins. Boulder is about 1m across, and sandstone/mudstone, area is volcanic.
I am not a geologist.. any ideas?

high arctic desert. Yes there's water, but no real vegetation.
