    Indeed you are correct sir. This panorama is looking WSW rather than ESE. That'll teach me to upload these things late at night, haha. According to the USGS, they have indeed classified Kohala as extinct. Most samples collected place the last eruption at around 120,000 years ago (while some samples collected in Waipio Valley place some sort of activity around 60,000 years ago.) In either case, the risk of eruption is such that they have classified the land around Kohala as either an 8 or 9 in terms of risk classification. (BTW - hows the new Epic Pro? I can't wait till they release it for sale!)

    Bradford, Judging from your geolocation marker, you may be physically close to the summit of the Dormant Kohala volcano (about 6 miles), but you're still 3,000 feet in elevation from the summit, and a long hike (not drive) into native forest, most unlike the pasture land around you. Even O`ahu has erupted within the last 50,000 years, and the Ko`olau volcano (eastern O`ahu) is about 2.5 million years old, and Kohala is about 450,000 years old. There was also an eruption on the south flank of Haleakala, Maui, in the late 1700's. Haleakala is about 750,000 years old. For Kohala, it's only a matter of time. Also, from your location, you can only look to the west to see the ocean.
