Taken at sunrise, near the Sparks Lake Campground, on a cold clear morning at 34f/1c degree morning in August. I find it hard to believe that some people were still sleeping in their tents and not seeing this. A fantastic morning.
The South Sister (left) is a dormant volcano, while Broken Top (right) is an extinct volcano. Behind me is Mt Bachelor, another dormant volcano. From this view, the Middle and North Sisters are hidden behind the South Sister.
The central Oregon Cascades are rich with volcanic history. With volcanoes; Mt. Jefferson, Three Fingered Jack, Black Butte, Mt. Washington, Blue Lake Crater, Belknap, North Sister, Middle Sister, South Sister, Broken Top, Mt Bachelor, and more. There are countless cinder codes (basically small “volanoes” that exist on the vents of the larger ones). There are even two of the extremely rare Tuya subglacial volanoes, Hayrick Butte (near a cinder cone named Hoodoo Butte with a ski resort on it) and the nearby Hogg Rock across Hwy–20. These form when a volcano erupts under a glacial ice sheet which results in a flat top and vertical walls. Every time I think of this, I wonder how thick that ice sheet had to be to “compress and cool” the magma to make those flat.
