<p><span class="EXLDetailsDisplayVal">Although historic literature is replete with anecdotes about atypical and far-reaching <span class="searchword">movements</span> of <span class="searchword">caribou</span>(<i>Rangifer tarandus granti</i>) herds in Alaska, very few such events have been described since the late 1970s proliferation of radio telemetry studies in the region. In September 1992, several herds in Alaska made unusual <span class="searchword">movements</span> away from their typical year-round ranges as a result of highly unusual weather conditions that affected a broad swath of the state. We describe the <span class="searchword">movements</span> of 113 radio collared <span class="searchword">caribou</span> from the <span class="searchword">Denali </span><span class="searchword">caribou</span> <span class="searchword">herd</span> during this phenomenon and the subsequent year. The majority of <span class="searchword">caribou</span> in the <span class="searchword">Denali</span> <span class="searchword">Herd</span> left their typical range during 26—28 September 1992, traveling distances up to 221 km and remained out of the area through much of the winter. While the out migration was highly consolidated and easily noticed, the return was protracted with <span class="searchword">caribou</span> drifting back to their typical range from October 1992 to early September 1993. All radio collared <span class="searchword">caribou</span> that survived the 1992—93 winter ultimately returned to their typical year-round range.</span> </p>
