Ice Bubbles

I went to a local wildlife nature area to look for ice bubbles and ice formations. One side of the lake was frozen but looked like it was thawing out but I still found some ice bubbles. Some I shot as single images, others I shot as multi-shot panoramas.  I shot quite a few so here are a few of the single shots from my morning out. All were shot with a 300mm lens with a 1.4x teleconverter @ f/11 to f/16.
