BELKNAP SHIELD VOLCANO - 1 The lava flow we visited on the way to Santiam pass is part
of the Belknap shield volcano, which lies on the axis of the Oregon high Cascade peaks
between the North Sister and Three-Finger Jack volcanos. Our bus could not go to Belknap,
but I was able to after the conference in a rental car. These views are taken from, and
near, the Dee Wright volcano observatory atop McKenzie pass. |
The Belknap shield volcano, viewed from the road at the top of McKenzie pass. Montage of three images; credit. To the left of the image is the long shallow slope of the shield, heading off the the basalt lava flow we visited along the road to Sanitam pass (Rich's flow). The steeper slopes that crown Belknap are of a cinder cone; another cinder cone is just below and right (east) of the crown (see next image). All the rock here is basalt. What is the hill slope angle of the Belknap shield volcano, and how does it compare with other basalt shield volcanos? |
