To me it highlights the risk of winter river travel.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-84834447287032231042015-12-11T14:21:10.120-09:002015-12-11T14:21:10.120-09:00I've been watching the Nenana Ice Classic cam ...I've been watching the Nenana Ice Classic cam daily, as well. What I've noticed from observing Alaskan rivers for many years is that once a substantial open hole survives the initial ice formation on a river, it is likely to take a long time to freeze over, even in below zero temperatures. The holes get a vertical ice edge, often quite thick, and slowly fill in horizontally as water freezes to the edge. <br /><br />I'm sure the Tanana River has been classified as "frozen" for weeks now, but perhaps with more open holes than usual due to the relatively brevity of the cold snap in November.
