Where the "Thunder Lizards" Once Roamed - Fishing the "Bear". You can easily say that it is a land frozen in time, a place shrouded in mystery and legend.  It is also a place of extreme contrasts as the millions of brilliant tundra flowers and the grave sites of past travellers will attest to.It is also an ancient place.  The people of Great Bear Lake - the Sahtu Dene have lived here since the beginning of time as we would perhaps understand it, and through the generations have handed down stories of Na acho - the gigantic mammals and birds that once roamed the earth.
