Hatcher Pass Avalanche Center

About HPAC

The mission of the Hatcher Pass Avalanche Center is to provide avalanche information and advisories to assist and educate the general public in avoiding avalanches. HPAC provides avalanche information and advisories for the Hatcher Pass area in the Talkeetna Mountains of Alaska.

Advisories are provided each Thursday and Saturday of the winter season, typically mid-Nov to mid-April. Avalanche warnings and significant weather and avalanche event updates are provided intermittently, depending on weather/avalanche events.  A public observation platform (in conjunction with the CNFAIC) is available all winter and monitored daily.

Allie Barker

Director and Avalanche Specialist

She is a current American Avalanche Association pro member, and has completed Avalanche Pro Level III, and is a Wilderness First Responder.  She has been an avalanche educator in Wyoming, Utah, Idaho, Colorado, Washington, and Alaska.  Allie loves spending time in the mountains and especially skiing.

Most recently, Allie has delved into avalanche mitigation as well as improving her backcountry snow machining skills.
