  1. Is vugs even the right term? Could some of them be lava tubes?

  2. Can you find the bald eagle?

  3. Located near the Sir James Open Pit this exposure is now somewhat weathered, but if you look closely you can see the outlines of some spectacular pillow lavas, evidence that there lavas were extruded on the seafloor before being incorporated into the Superior Craton.

  4. This is the roadcut exposure through the same lava flow seen in another GigaPan that's currently uploading. The top of the flow is visible at the top of this view. In this old lava flow, vesicles (gas bubbles) are now filled with secondary minerals, making them amygdules. Compare the concentration of amygdules from ...

  5. The tilted surface of a Keweenawan lava flow on the east shore of Lake Superior.

  6. Main entrance of Balcoes Cave in Terceira Island

  7. Sometime around the year 500 small quantities of ash and lava erupted from St. Helens' north flank. This period ended with the emplacement of dacite domes, including Sugar Bowl around the year 800. The Sugar Bowl dome is a nearly circular protrusion of hypersthene-hornblende dacite, about 800 m in diameter, on the nort...

  8. Windy Ridge is one of the best places to get an overview of the area devastated by the 1980 eruption of Mount St. Helens. The landscape is littered with sand and gray rocks from that event. Deposits of the debris avalanche are visible to the west. These include the lower parts of The Spillover, where the debris avalanc...

  9. The Johnston Ridge Observatory sits on a bluff just 5-1/2 miles from the crater at an elevation of 4,314'/1,327m and offers grand views of Mount St. Helens and much of the 1980 blast zone. Here you can enjoy spectacular views of the lava dome, crater, pumice plain and the landslide deposit.
