We survived the Polar Vortex, most importantly, Grizzer at the age of nearly 17, survived the Polar Vortex with rural Ely breaking a record of -50.2 below zero.  We were a bit warmer up on the hill at the Center with -37 being our coldest.   The use  of the Wolf Care Center, a 70 degree building for morning feedings and extra food resources made the days more tolerable.  Now that the weather is moderating, we are able to feed more carcasses that will stay thawed for more than an hour when sitting in the snowbanks of the enclosure.   Grizzer can easily defend his food from Denali, but if not, staff have back up dinners prepared.
