Delicately balanced on ice, trying to spread my weight so as not to break though, I gingerly prepare to shoot a 360* panorama on a partially frozen river... It is hard to tell the scale in this image, so for reference: some of those icicles are close to 15 feet long! With some of the best hexogonally faulted basalt to be found, Svartifoss was my favorite waterfall in southern Iceland.
