While beginning to photograph interesting ice patterns left by the dropping tide, I realized there were two men in hi-viz down there stringing some devices along the shore. They look like they may be sensors of some sort, but I can't see them lasting very long. They also look like they could be explosive charges. They were going around here some years ago with similar sensors and a ground shaking machine to see about fracking. Not sure how that went, but I've seen no new wells in town. I wonder if they could have anything to do with the bubbles I've been seeing or those strange icy blobs floating around earlier? #sonydschx400v #sonydsc #sonycybershot #SonyCameras #kenairiver #kenairiverbank #kenairiverlowtide #whataretheydoing #kenai #kenaialaska (at Kenai, Alaska) https://www.instagram.com/p/CWm6gbBrd53/?utm_medium=tumblr
