Avalanche Control
TFR Descriptions

Temporary Flight Restrictions Coordinated with Alaska DOT

Update Friday February 14, 2014


When necessary for avalanche control, the State of Alaska, Department of Transportation (DOT) will call Anchorage ARTCC Watch Desk (907) 269-1103 and request that TFRs be placed around areas of live firing for avalanche control. At times, they will only have an hour or two, for notification purposes, prior to firing. Listed below are the areas of control and altitudes that they will be requesting. The State of Alaska DOT employees will use the Pass name and Block numbers to refer to each individual TFR. The FAA will issue each NOTAM using the coordinates specified below.
